When it comes to packaging products with shrink wrap, there are two different ways to finish the process. One is by use of a heat gun and the other is by use of a heat tunnel. Both will get the job done. So which system should you use? I’ll explain the differences here.

The biggest and probably most fundamental difference between a heat gun and a heat tunnel is speed. A heat tunnel is significantly faster than a heat gun. Here is a brief description of the two different designs:

• Heat Tunnels – Heat tunnels typically use some sort of conveyor system that transports the product. The tunnel is heated and blows hot air around the product, causing the shrink film to contract thus completing the packaging process. Heat tunnels are not only known for their speed, but also for their ability to evenly shrink film. Heat tunnels are often located to the side of a shrink wrap machine. Many machines now include a built-in heat tunnel. This process usually takes just seconds.
• Heat Guns – Heat guns are essentially glorified hair driers, however, much hotter. They are manually held and manually operated. The operator typically blows hot air on one side of the product, flips it, and then shrinks the film on the other side. This process can take anywhere from 10-60 seconds, depending on the size of the product and the experience of the operator.

Apart from speed, price is also a differentiating factor. Heat tunnels are more of an investment where heat guns are a fraction the cost.

You really need to analyze how many products you need to package per day and where you expect your production volume to be years down the road prior to making a purchase. Heat tunnels can be used to package hundreds to thousands of products a day where heat guns are typically used for a few dozen to hundreds per day.

Both heat tunnels and heat guns will probably last you for years, so be sure your decision today doesn’t adversely affect your job later down the road.

We often get asked which shrink wrap machine is best for daily packaging of a variety of different products. This may involved CDs, soap, chocolate, software and more. I have a couple of great options.

There are two primary types of shrink wrap machines. The first type is an I-bar (straight bar) and the second is an L-bar. The machine you get will depend on your preference and the volume you are packaging.

An I-bar sealer has a single cutting bar that cuts and seals the film. Because it only cuts one side at a time, it usually requires two passes to completely encapsulate a product. Why only two passes?

Assuming you are using centerfold shrink wrap film, the folded side is already sealed leaving three open sides.

Every time an I-bar sealer is used, not only does it cut the film for your package, but it also seals one side of the film for the next package. This leaves a total of two open sides for each consecutive package.  A heat gun is typically used to shrink the film.

An L-bar sealer has two cutting and sealing bars, in the shape of an L. As previously described with the I-bar sealer, the film usually only has two open sizes, which means an L-bar sealer will completely encapsulate a packaging in one pass. Many L-bar sealers come with a heat tunnel, although a heat gun may be used.

We have two recommended I-bar and two recommended L-bar sealers for your daily packaging needs. These are as follows:

Top I-Bar Sealers

• Super Sealer – Deluxe Model with Heat Gun
• AIE I-Bar Shrink Wrap System With Gun

Top L-Bar Sealers

• Minipack Galaxy Shrink Wrap System
• Minipack Galileo Shrink Wrap System

It’s amazing how many people are now reigning in once outsourced packaging operations to in-house. Why is this? A huge part of it is because it isn’t difficult for a business to package their own products. It is also a great way to save money during a recession.

Shrink wrap machines have become smaller, easier to use and far more affordable. Minipack has been on the forefront of this revolution. Two of their most popular machines are the Minipack Galaxy and Galileo machines. You can find them here.

The Galaxy and the Galileo shrink wrap machines replaced the Mini-Plus and the Mini-Mini shrink wrap machines. The Galaxy and Galileo are essentially the same machine, but with different chamber dimensions. Both the Galaxy and Galileo are available in different setups. These have been broken down into systems. The system you use depends entirely on what you need.

Both of these machines have an integrated heat tunnel. This means that when the hood is brought down, it will cut the film around the package and shrink it in one single pass. This is very quick and very convenient. Packaging a DVD, software box, pizza or soap bar can be done in just a few seconds. You can use these to package food by using polyolefin film.

The Galaxy and Galileo are very easy to use and set up. There is no special training required. Maintenance is also easy.

Both of these machines are very efficient and emit very little odor. This is especially nice when being used in poorly ventilated rooms. These machines can use both PVC and Polyolefin film. You can learn more about the two different types of film by going here.

We have had customers ask if the heat will damage products. While there may be some heat-sensitive products you will not want to package, we have had customers send in chocolate samples for testing and haven’t had a problem with the heat melting anything.

If you are interested in the Minipack Galaxy or Galileo, send a sample into us and we will test it out on these machines. We can then send the sample back to you for your approval.

We are also able to offer live video demonstrations of these machines through the Internet. If you are interested in having one of these machines demonstrated for you, simply one of these forms:

There are two types of shrink wrap film typically used with shrink wrap machines. These are PVC and Polyolefin shrink wrap. Both are very popular, but both have several differences that you will want to be aware of before purchasing shrink wrap supplies.

You may be most familiar with PVC shrink wrap film. This is because most DVDs, CDs and software boxes are packaged with PVC film. PVC film is typically a little less expensive than Polyolefin.

PVC film is more brittle, making it easier to break open. This is nice for opening packaging, but is a disadvantage if you are shrink wrapping multiple products together. Why would that be? This is because the brittle properties of the PVC film could cause packaging of multiple items to rupture more easily than Polyolefin.

PVC film emits an odor that some people may not appreciate. It is recommended to use PVC film in a well-ventilated room. PVC film is not safe to use with food.

Polyolefin film is growing in popularity, especially because it is safe to use with food. The stretchy properties of Polyolefin film also make it ideal for group packaging of products. Polyolefin emits little to no odor.

Both types of film can be used with most shrink wrap machines, whether they be I-bar or L-bar systems. Both heat shrink guns and heat tunnels can shrink these types of film.

At ABC Office we sell both types of film in various lengths and thicknesses. Take a look at our selection of shrink wrap film here.
