KF-772DH Clam Shell Sealer Review

Thursday, August 29th, 2013

KF-772DH Clam Shell Packaging SealerClam shell packaging is one of the most common and reliable ways to package a variety of products. Clam shell packaging itself is usually rectangular in shape, although it can be more form fitting to better accommodate the product being packaged. Clam shell sealers (found here) are used to quickly seal clam shell packaging shut. The KF-772DH (found here) is one model you may want to consider using. This is my review.

Clam shell packaging has been around for years. Years ago it was almost always fastened shut using a stapler. It was found, however, that staples would eventually runs (looking bad) and that the staples could be easily pried open and products removed. There was also the issue of staples pricking fingers when packaging was opened. These are all reasons clam shell sealers came into being.

So how exactly does a clam shell sealer work? It’s actually fairly simple. Clam shell packaging opens up like a clam (hence the name). To keep the mouth of the clam shell packaging shut, it has to be sealed. Clam shell sealers use heat, or other methods, to melt the two halves together, sealing them shut. This is often referred to as plastic welding. Usually the packaging is sealed on the front and sometimes on the sides as well.

One advantage to a clam shell sealer is that there are no supplies involved, such as staples. Also, the packaging is very difficult to tamper with. If you have ever purchased something sealed with a clam shell sealer, you have probably had to use scissors to cut the plastic in order to access the contents. While a little annoying open, it is very secure and professional.

The KF-772DH is a direct heat (aka constant heat) clam shell sealer. This means it uses heat to literally melt the clam shell packaging. It comes equipped with a switch that can be toggled from low (250F / 120C) to high (350F / 175C). This allows the KF-772DH to be easily used with packaging made from OPS, PSP, PVS and EPC plastic cases.  The sealing process really only takes a few seconds.

Here is a video demo of the KF-772DH in use:

While the sealing jaws on the KF-772DH do get very hot, the handles are insulated and cool to touch. Within the handle is a spring that returns the jaws to an open position after being used. A hook can be used to keep the handles in the closed position when the clam shell hand sealer isn’t being used. It works a lot like a handheld hole punch. It only weighs 10 ounces, so it is really easy to use repeatedly.

The weld produced by the KF-772DH is rectangular in shape. It measures in at 4mm x 10mm in size. This weld is extremely secure and from what I’ve seen it is just as secure and professional as what you would find with any other direct heat hand sealer.

While a lot has been put into this design to prevent injury, the operator should still try and keep their hands away from the jaw. I recommend you wait at least 30 minutes to ensure everything is properly cooled down before handling the serrated sealing jaws. A lot of the safety with this sealer involves some basic common sense.

I hope this review helps answer some of your questions. If you need some additional information, please feel free to give us a call at 1-800-658-8788.

Best Types of Clam Shell Sealers

Wednesday, August 14th, 2013

Direct Heat Clam Shell SealerHave you ever purchased something at a store and it was sealed in a thick plastic shell? This is what’s known as clam shell packaging. It is packaging that opens and closes like a clam with three open sides. Scissors are often used to open this kind of packaging (or a little muscle). Years ago staplers were used to seal this type of packaging, but today most people use clam shell sealers (found here). So what is a clam shell sealer and what types are available? I’ll explain more in this article.

As mentioned earlier, years ago staples where commonly used to keep clam shell packaging closed. The downside to this is that the staples would eventually begin to rust and oxidize, making the packaging look awful. There was also the safety issue. Staples can puncture skin and potentially cause a minor injury. For this reason, most people have abandoned staples as a method for closing clam shell packaging.

Clam shell sealers, often called packaging spot welders, actually cause the top and bottom half of the clam shell packaging to melt together. This is usually done in a couple of spots on the opening side of the packaging. The sides are often left alone, although they can be sealed as well if the clam shell packaging is large. Clam shell sealers also don’t require any supplies, such as staples, to operate. Clam shell sealers range in size depending on the volume of packaging. Some are fairly automated where others are handheld.

There are two main types of technology used in clam shell sealers. The model you use will depend on several factors. Here are the types you have to choose from:

Direct Heat Clam Shell Sealer – These sealers are very popular and very common because they are so affordable. These sealers use constant heat to melt the plastic together. The concept is very simple and straightforward. They use clamping jaws and look much like a set of high-tech pliers. Some of these have a variable temperature dial where others simply have a high or low setting. Direct heat sealers are designed to work with most types of packaging including those made from OPS, PSP, PVC and EPS materials.

The KF-772DH (found here) is a great example of a direct heat clam shell sealer. It has two heated jaws that can be used to tight spot weld plastic in a 4mm x 10mm spot. This particular unit is a dual temperature model with the high temperature at 350 F and the low at 250 F. It looks a lot like a pair of pliers and it is extremely easy to maneuver. The handles are insulated, keeping them nice and cool during use.

Here’s a video demo of the KF-772DH in action:

OnPak Ultrasonic Clam Shell SealerUltrasonic Clam Shell Sealer – If you’re concerned about safety, or you want to speed up packaging operations, you may want to consider an ultrasonic clam shell sealer. These sealers use ultrasonic vibration technology to melt and weld the plastic together rather than direct heat. As a result, there is no need to worry about being burned. These sealers are also extremely quick to use and operate. These sealers also remain remarkably clean and efficient with continued use. These sealers will work with PSP, OPS, HIPS, PPF, PP and A-PET. Some will even work with PVC clam shell packaging (verify this before purchasing a machine).

The OnPak Ultrasonic clam shell sealer (found here) is a great example of an ultrasonic unit that has PVC sealing capabilities. It works a lot like a small handheld stapler and produces a seal that measures in at 3mm x 6mm. Because it is ultrasonic, no warm up time is required.

Here’s a video demo of the OnPak in action:

Using a handheld clam shell sealer is a great way for you to affordably package your own products. The process is very simple and very little training is required to operate one of these machines. This can allow you to package products from the convenience of your own home or a desk / table. Most of these machines weigh very little. In my experience, the direct heat sealers weigh a little more than the ultrasonic sealers.

We have decades of experience handling and dealing with packaging products and supplies.

Three Affordable Options for Packaging Your Own Cds or Dvds

Monday, July 29th, 2013

CD & DVD Shrink Wrap Packaging MachinesHave you ever thought about packaging your own CDs, DVDs, Blu-Rays or video game cases, but never really knew where to start? It isn’t really that hard and most packaging processes take just a few seconds. There are many different options out there with some of them being affordable enough to do in your own home. This is primarily done using a process called shrink wrap (found here). Machine options range from entry-level units to high-end machines.

Shrink wrapping is actually a very simple process. A product is placed in some sort of film pocket or sleeve, the open ends are sealed shut and heat is run over the plastic. Shrink wrap film is made from a thermoplastic material, so when heat is run over it the film begins to contract. This process is what creates a clear stretched film over CDs, DVDs and Blu-rays that you buy in the store.

As mentioned earlier, machines for shrink wrapping media material come in a variety of sizes. Some are designed for packaging a few dozen to a few hundred a day, where some of the larger systems are designed to package thousands to tens of thousands a day. I would like to point out some of the most affordable machines in an effort to help you get the most for your money.

Sealer Sales SWK-8-04 Heat Sealer (found here) – These kits consist of thermoplastic shrink bags (500 total), a heat sealer (used for sealing the open ends) and a high-end heat gun that is used for shrinking down the film. These kits are available for less than $100 and can be used for home or small business packaging needs.

AIE I-Bar Sealers (found here) – These machines are very versatile and can be used for packaging CDs, DVDs, Blu-rays and other stuff as well. These machines use what’s known in the packaging industry as centerfold film. Basically it is a long sheet of film that has been folded in half and rolled up. Because the film is folded in half, a pocket is formed. The width of the film is determined by the roll, but the length can be set by the operator.

Once the product is inserted into the centerfold film, the open ends are sealed shut using the I-bar. The film can then be quickly shrunk down using the included heat gun. This particular machine includes a 500-foot roll of centerfold film.

Here is a video of an AIE I-bar sealer in use:

Truline TP-48ST Shrink Wrap System (found here) – If you need to increase your packaging speed, you may want to consider using a shrink wrap system. These machines are designed to package several hundred to thousand products a day. The TP-48ST is an L-bar sealer, which means it seals all open sides on a centerfold roll of film in a single pass. It also includes an integrated heat tunnel that seals and shrinks the film in a single pass. This model can be used with a standard wall outlet, which means no special power requirements are needed.

Here s a video of the TP-48ST in use:

These are three solid options that I recommend you consider when packaging CDs, DVDs, Blu-rays or video game cases. The seal is extremely durable, provides tamper proof packaging and is very professional. The results from any of these machines will look just as professional as anything you’ll see in your local retail store.

We have been selling shrink wrap machines and supplies since 1980, so we have a lot of experience behind us to help you find the right machine for the job. If you have any questions, please feel free to give us a call at 1-800-658-8788. We would love to help you out.

How Do Induction Cap Sealers Work?

Monday, July 22nd, 2013

Induction Cap Sealers / Foil Lid Sealing MachinesWe recently added a couple new induction cap sealers to our site (found here). While I was familiar with what they did, I didn’t really understand how the technology worked. These sealers are the machines that place the protective foil seal to the top of bottles. This includes such products as food, cosmetics and much more. After having thoroughly researched this, I would like to share with you exactly how these machines work.

Induction cap sealers are used with just about every consumable product you use. These sealers produce a tamper proof seal that helps preserve freshness, prevent leaks, provide tamper evidence, helps with pilferage protection and extend shelf life. You may have seen a sign on the top of these seals that says something to the effect, “Do not use if seal is broken”. The technology used to apply these seals is remarkably clever and efficient.

Induction Foil Bottle SealThe seal they apply to the opening of a glass or plastic container is usually made out of a foil barrier, although other materials can be used. The foil consists of a few layers of laminated products and uses a sealing resin or a polymer to produce the seal. This results in a very sturdy and durable seal that won’t break or fall off.

It’s amazing how much these seals are used in products we handle every day. Just this week I changed the oil on my car and the quart bottles each had a foil seal. The yogurt I ate this morning had a foil seal. I even opened up a new bottle of ketchup this week and it too had an induction sealed foil cap.

So how does this technology work? It is remarkably simple and there are no moving parts during any part of the sealing process. The first step involved is to insert a seal into the lid of the product being sealed. This can be manually done or automatic, depending on the packaging system being used. Once the lid is screwed on (manually or automatic), the bottle is run under an induction sealer.

The induction sealer uses electrical current run through induction coils to produce a strong electromagnetic field. This field causes the foil to heat up, which in turn causes the membrane (using sealing resin or polymer) to seal to the top of the bottle. The process is extremely fast, usually only taking a few seconds. Because an electrometric is used, you should only use this type of sealing process with plastic or glass containers. Do not use this with metal containers.

Example of Induction Foil Cap Seal on BottleInduction cap sealers range in size from tabletop units to full blown automatic production-level machines. At ABC Office we offer semi-automated. We currently offer two models, but expect this to increase. Here are the two models currently offered on our site:

  • AF-500W Induction Cap Sealer (found here) – This particular model is designed to be used with containers that have a diameter opening ranging from 15mm up to 120mm. The height of the sealer can be adjusted to accommodate the bottle being sealed. Simply place your bottle on the platform, press the foot pedal and in just a few seconds the process is complete.
  • CS-501 Induction Cap Sealer (found here) – This induction sealer is very similar to the AF-500W, but is more robust. Instead of a 500-watt power supply, this one has an 1100 watt power supply. It also includes the addition of a cap sealer, which will automatically screw on the cap and inductively seal the membrane to the container’s opening.

Our induction bottle cap sealers are designed to seal the foil membrane without any scorching and zero leaks. They can even apply a seal to the lid of small amounts of liquid or powder are on the rim of the bottle. These sealers are tough, designed to be used on a daily basis. They also have a small footprint and don’t require any special training to use.

If you still have questions about induction cap sealers, please don’t hesitate to give us a call at 1-800-658-8788. We would love to help you out.

Clear Stand Up Zip Lock Pouches Now Available

Friday, July 12th, 2013

Clear Stand Up Ziplock Pouches & BagsIf you’ve been to the grocery store and have purchase a bag of beef jerky, trail mix, dehydrated fruit or nuts, you have probably noticed that many of the packages now include a ziplock style opening on the top that makes the bag easy to open and close. This is an excellent addition to packaging, helps keep things fresh and eliminates the need to use a twist tie. At ABC Office we have just added those very same stand up zip lock pouches (found here) to package your own food products.

These new stand up pouches work very similarly to other bag sealer bags. It essentially ships as a flat bag with an open top. When expanded, the bag is then able to stand up thanks to a gusset bottom. Nuts, cookies, candies and other food items can then be placed in the after which the bag can be sealed shut using a heat sealer (found here). The entire process is extremely simple and best of all it can be done by just about anyone. A sealed zip lock is included on the bag, providing access to the contents by the consumer.

Right now we offer ten different sizes of bags. This includes five OPP / CPP bags and then five PET / CPP (Y Version) bags that are freezer safe. The mil thickness of the plastic used gets thicker as the bag gets bigger. Mil thickness ranges anywhere from 4 mil to 13 mil thick, again depending on the size of the bag. Our smallest bag measures in at 4” x 6” x 2.5” and our largest bag measures in at 7” x 12” x 4” (Height x Width x Gusset). These bags are the perfect sizes for snacks.

The plastic used in these bags is FDA approved for use with food and is manufactured in a multilayer barrier design to help ensure durability. These bags will stand straight up when placed on a shelf. These bags are completely clear, making the contents easy to see. These stand up pouches can be used for packaging your own food at home for food storage purposes or for retail sale at a farmer’s market, grocery store and much more.

Stand Up Zip Lock Pouches from Sealer SalesMost of the bag sealers, impulse sealers and direct heat sealers we offer online are compatible with these bags as they react to direct thermal sealing. Our heat sealers come in different sealing widths, depending on your personal preference and how much durability you would like at the top of the bag. You can use these with hand sealers or foot sealers.

While these bags come in quantities of 250 or 500 pieces per box, we can get these to you in much higher quantities, often at a bulk discount. If you have questions, or need additional information or pricing, feel free to give us a call at 1-800-658-8788. We would love to help you out and help you find the appropriate packaging material for your storage or retail needs.

Have you used these bags or do you have experience with them? Feel free to post your experience as a comment. I would love to hear from you. Thanks for reading and have a great day!

Continuous Band Sealers – Everything You Need to Know

Friday, June 14th, 2013

Continuous Band SealersIf you are sealing bags on a daily basis and your volume is going up into the hundreds or even thousands per day, you may want to upgrade from your hand sealer and consider using a continuous band sealer (found here). These machines are designed to quickly seal a variety of thermoplastic bags shut at a high rate of speed. Many can seal anywhere from 20-30 bags per minute. These machines are used for packaging such products as liquids, powders, food, medical devices, parts and much more. This article will cover the different types of continuous band sealers available.

Continuous band sealers could almost be called automated bag sealers, because that is what they do. They take a bag and seal it with very little manual involvement. The operator of the machine takes the bag and inserts it into the machine where it then takes it and seals the bag shut. The bag is carried along a rubber conveyor until the process is done. Many of these sealers will seal up to 40 feet of bag per minute, which is extremely fast.

So what do these machines do? They seal the top of an open plastic bag shut for storage, packaging and retail purposes. This is done by using direct heat to melt the bag shut in a straight linear pattern. The width of the seal varies, depending on the machine. Most of the band sealers we offer produce an 8mm thick seal, however, some go as high as 15mm thick. The thicker the seal, the stronger the hold. You have probably seen examples of packaging sealed with a band sealer in the grocery store. Pretty much any bagged product you use has been sealed this way.

Most of the bags used with these machines are made using thermoplastic material that reacts with heat. This includes PP, PE, Laminates, stand up pouches, gusseted bags, moisture barrier bags and more. Continuous band sealers are available in several configurations, depending on the size of the bag you need to seal, the weight of the material being packaged, what you are packaging and much more. Here are a few things you may want to know when shopping around for a machine:

Horizontal or Vertical – Band sealers typically come in a horizontal or vertical configuration. This means they can seal a bag laying down or standing up. The design you get depends a lot on what you are sealing. Most people go with a horizontal design unless they are packaging something that could spill. If the bag contains powders, liquids, small pieces and other spillable items, you will want a vertical sealer.

Here is an example of a horizontal band sealer in action:

Here is an example of a vertical band sealer in action:

Tilting Head – Some of the vertical band sealers we offer have a tilting head to help assist with packaging liquids. Some of these sealers have a head that will tilt up to 30 degrees to assist with the sealing process.

Conveyor – Many band sealers offer the option of adjusting the height and depth of the conveyor. This is designed to accommodate the bag size. If the adjustments aren’t correct, it can make bag sealing more complicated.

Printing – Several band sealers offer the option of printing text and numbers along the seal. This may include the date, serial numbers and much more. There are several different methods of printing, depending on the machine. Here are the four most common:

  • Dry Ink Coding: This method prints black text or numbers along the band.
  • Color Ribbon Printing: Color ribbon printing provides a stronger adhesion print than dry ink coding and works best for humid environments.
  • Embossing Attachment: This method allows text to be embossed with heat along the band. This method does not use any ink.
  • Hot Ink Coding: Uses a hot ink method to print text and numbers along the sealing band.

This is a video of dry ink coding in action:

 

Most of the continuous band sealers we offer are made using stainless steel for food packaging purposes. Designs range from tabletop to floor models that include a stand and casters. Typically the larger the machine, the more throughput it allows.

Most of these sealers allow the operator to adjust the temperature, speed, fan control and much more. The control panels on these machines keep the settings all in a single location and the bulk majority of them are incredibly easy to set up and don’t require any special training to use.

You can find our entire selection of continuous band sealers here. Please feel free to give us a call at 1-800-658-8788 with any questions. We would love to help you out.

Preferred Pack TZ-888 Banding Machine Review

Tuesday, May 14th, 2013

Preferred Pack TZ-888 Banding MachineIf you have the need to bundle paper, business cards, brochures, money, paper towels and other products together, you should consider using a banding machine. Banding machines can use either plastic or paper bands to quickly bundle items together. This is excellent for storage, retail, shipping and other purposes. One of the most affordable and durable banding machines we currently offer is the Preferred Pack TZ-888 (found here). This particular banding machine is available in two different versions, depending on the size of the items you are trying to package. This is my review.

Many people get strapping machines and banding machines mixed up. They are actually two totally different machines. Strapping machines are use hard plastic strips to keep boxes closed during shipping. Banding machines use wide strips of paper or plastic to bundle multiple items together. While similar, they are two very different machines used for very different purposes.

I recently handled a product in the wild that had been bundled. Have you ever seen a stack of paper towels that need to be put into a dispenser? These towels are often bundled together using a banding machine. You have to tear the paper band off in order to use the paper towels. Other products that are bundled, as mentioned earlier, includes literature, business cards, pamphlets, brochures and much more. The size of banding machine you get depends entirely on what you are bundling together.

I highly recommend, when shopping for a banding machine, to be sure the machine can accommodate your biggest item and that it can handle your future banding needs as well. These machines are versatile and can be adjusted to accommodate a variety of items, but they all cap out at a maximum size. The TZ-888 can bundle packages from 0.25″ H x 1.5″ W up to 5.5″H x 9.5″W. The larger TZ-888A can bundle packages from 0.25″H x 1.5″W up to 6.7″H x 10.5″W. Both of these machines use tape rolls up to 500 feet white that are made from paper (white / brown) or plastic (clear).

Bands can be applied in a variety of positions, based on what you are bundling and where you need the most security. Here is a video of the TZ-888 in action:

Get the Flash Player to see this content.

Both of these banding machines are compact and both can be used on just about any desk or surface. They both plug into any standard wall outlet. Both have an operational speed of about 20-25 bundles per minute. Speed is really limited by the experience of the operator and the size of the package being bundled.

So how do these machines work? It is very simple. There are three different ways to run it. You can switch it to automatic mode where it will bundle when something triggers the photo sensor. You can also press a button to bundle or press an included foot pedal. This machine will wrap the band around the product, tighten it, cut it and seal the open ends shut. The process is fast, accurate and remarkably secure.

The build quality on the TZ-888 and TZ-888A (with arches) is tough and excellent for daily use. If you need something even bigger, we also offer the TZ-889 and TZ-889A banding machines (found here).

Please feel free to give us a call at 1-800-658-8788 with any questions. We would love to help you out. You can find our entire selection of banding machines here.

TP-48ST “All In One” Shrink Wrap Machine Review

Friday, May 10th, 2013

Truline All-in-One TP-48ST Shrink Wrap MachineIf you were a big fan of the Minipack Galaxy, the Minipack Mini or other compact Minipack shrink wrap machines, you may be finding it hard to find an affordable replacement. If you’re stuck in this boat, I would like to recommend that you consider the Truline TP-48ST (aka PP-48ST and 48-ST) found here. We have been offering this machine for a few years now and have found it to be an affordable and comparable replacement. Here are a few reasons why.

There are a lot of reasons why I really like this machine. Here are just a few:

  • Power Supply – Many people want a shrink wrap machine that they can simply plug into a wall and use. They don’t want to have to call in the electrician or have to deal with special power requirements. The TP-48ST can be plugged into a standard wall outlet. This means it can be used almost anywhere a wall outlet is available. This is a huge plus. As of this article, Minipack doesn’t offer any shrink wrap machines with a 110-120 volt power supply.
  • Chamber Size – The TP-48ST has a 12″L x 18.5.”W x 6″H sealing chamber. This is ample room for packaging small boxes, CDs, DVDs, chocolates and other products. This is a nice well-rounded size for most people. If you need a bigger chamber, you may want to consider the Truline TP-76ST (found here).
  • Heat Tunnel – I-bar sealers and many shrink wrap systems use an independent heat tunnel or heat gun. The TP-48ST uses an integrated heat tunnel. This helps save on space and is extremely convenient for single step operation. Simply place your product in the film, pull down the hood and the TP-48ST will seal the product and shrink the film down in a single pass. A clear hood lets you see what is going on during the packaging and sealing process. It also includes a magnetic lock that keeps the hood down during the sealing and shrinking process.
  • Controls – The controls are right in front of the machine and are pretty straightforward. They are located on the front of the machine and can be used to adjust the heat, tunnel time, sealing time and more. The results are very professional.
  • Film Compatibility – The TP-48ST can be used with both PVC and Polyolefin film. Polyolefin film, sometimes called poly film, can be used with food. Both types of film are very professional and can be used to package a wide range of products. The TP-48ST is designed to be used with centerfold shrink film and even includes a film dispenser, a film perforator and a film opener.

This machine is available from Truline as the TP-48ST and Excel Packaging as the PP-48ST. They are the same machine just with a different label slapped on them. This machine is also sometimes referred to simply as the 48-ST.

Here is a video demo of the TP-48ST in use:

Get the Flash Player to see this content.

Besides the fact that this machine comes equipped with a lot of nice features, it is also really compact. For what it is and considering what it does, it really doesn’t take up a lot of space. It also sits on casters, making it really easy to move around. Two of the casters can be locked into place, keeping the machine stationary.

If you’re on a budget, and need something that produces reliable and professional results, this is definitely the machine to consider. You can find the TP-48ST here and our entire selection of shrink wrap systems here.

Best Way to Shrink Wrap Paper for Archival Storage

Monday, May 6th, 2013

Shrink Wrap Machines for Paper Archival PurposesDoes your business deal with stacks of papers, contracts, invoices or other paperwork and are looking for an effective way to package and archive this material? One of the most popular tools used to do just that is shrink wrap (found here). ABC Office has been selling shrink wrap machines for decades, with several models recommended for doing just this. I would like to answer a few common questions and offer a few machine recommendations.

Over time, businesses and organizations begin to accumulate paperwork such as invoices, contracts and other material. While it is a good idea to keep some of this paperwork accessible, eventually it becomes cumbersome and takes up too much space in a filing cabinet. Because most businesses don’t need paperwork going back more than a few years, many opt to archive older documents. Even here at ABC Office we eventually have to remove old invoices from our filing cabinets and archive them.

Shrink wrap has quickly become one of the most popular tools for archiving documents. This is because shrink wrap helps bundle and hold paperwork tightly together (thanks to the shrinking properties of the film). The plastic barrier created by shrink wrap also helps keep the paperwork protected, helping provide a barrier against insects, animals, moisture, dust and much more. We have customers that often use shrink wrap to bundle invoices and contracts alphabetically by year. They’ll take all of the invoices that are sorted by the letter “A” and shrink wrap those together. Customers will then take this paper and write on it with a marker or slap a label on it. These stacks of paper can then later be opened (if needed) and re-wrapped with shrink wrap film.

There are several factors to consider when buying a machine and film. I would like to answer a few common questions.

  • How much paperwork are you archiving? If you are only packaging a few hundred documents a day, a machine like an I-bar sealer (found here) may be adequate. If you are packaging a lot of paperwork per day, perhaps in the thousands of sheets per day, I recommend you use a shrink wrap system (found here) that includes an integrated heat tunnel. Keep in mind that an I-bar sealer uses a heat gun, which does require the operator to manually shrink all four sides. If you are dealing with a cumbersome stack of paper, you may need something more robust than just a heat gun (especially when shrinking the bottom of the stack).
  • How large are the documents you are packaging? The size of the stack of paper you are packaging will be one of the biggest determining factors in which machine you purchase. You need to take into account the length, width and height of the stack you need to package. I recommend once you have established the width in height, that you add a few inches on top of that to ensure there is ample room. When it comes to establishing the sealing width you need, I recommend you add the width of the stack plus the height of the stack and add four inches to that number (Width + Height + 4″).
  • What type of film should you use? I would say this also depends on the size of the paper (length & width) and the height of the stack. If you are only packaging letter-size paper no more than a ream thick, you are probably going to be fine using 75 gauge PVC film. If the stack is thick, or the size of the paper sheet is large, you may want to use polyolefin film. Poly film has more flexibility to it (much like stretch wrap) and won’t break or tear nearly as easily as PVC film. You can find both our PVC and our Polyolefin film here.

At ABC Office we use the Compack 5800 (found here) to package our old letter size invoices. It is ideal for medium to higher-volume use. Again, the machine you use will depend on the job you need to do. Just be sure to take into consideration how much your volume may increase over the years. Please feel free to contact us at 1-800-658-8788 with any shrink wrap or document archival questions.

Preferred Pack PP615-402 Gravity Drop SealerHave you ever wondered how food, such as tortillas, is packaged in those bags you see at the grocery store? Much of it is done by using a gravity drop sealer (found here). These same sealers are also used to package T-shirts, towels, books and much more. If you are in the market for a drop sealer, or if you are just curious how they work, I would like to introduce you to two new models we just added to our site. These are the Preferred Pack PP615-402 (found here) and the PP620-405 (found here). I would like to cover exactly what these machines do and include a video.

Gravity drop conveyors are special packaging machines that use gravity to help package products in a bag. In a nutshell, a product is placed in a bag, then sealed and finally dropped into a catch tray or bin. This process is repeated over and over as products are packaged throughout the day.

The new Preferred Pack drop sealers we just added take this process a step further by automating much of it. Our drop sealers include the addition of a bag opener, to help facilitate the packaging process. The bag sealer takes a bag from the top of a stack and opens it using forced air. A product is then inserted into this bag where it is slid down a gravity slide. Special holding pins help prevent the bag from sliding the rest of the way down. A sealing jaw then seals the bag shut and cuts off excess plastic. These machines then use a burst of air to clear off the excess plastic, after which the holding pins are released, allowing the bag to continue its journey into a catch tray.

Here is a video demo of one of these new drop sealers in action with tortillas:

As you can see the process has been streamlined and is remarkably easy to do. This is a must have tool if you are packaging a lot of food (or non-food) items on a daily basis. The packaging is extremely professional and the end results (including the seal) hold up well with handling.

We currently offer two different versions of this drop sealer on our site. These include:

  • Preferred Pack PP615-402 (found here) – This version of the drop sealer includes the bag opener and includes a sealer that can be used with bags up to 15″ wide. It can be operated at a speed of up to 25 bags per minute. It can be used with a bag up to 10 mil thick.
  • Preferred Pack PP620-405 (found here) – This version of the drop sealer also includes a bag opener and features the ability to seal bags up to 20″ wide. Like the smaller model, this can also be used to package about 25 bags a minute. This model can also be used with packaging bags of up to 10 mil thick.

Both of these gravity drop sealers feature a warranty that guarantees they will be free from defects in materials and workmanship for two years.
