Soft Air “Pillow Pack” Option for Minipack Chamber Vacuum Sealers

Minipack MVS 45X Chamber Vacuum SealerWe recently had a customer approach us who was interested in packaging his own pizzas for long term storage using a vacuum sealer. He appreciated the preservation nature of vacuum sealing, but didn’t want his pizzas to be totally crushed by having 99.9% of the air removed. He was in need of a solution to this problem. Luckily Minipack has had these types of inquiries before. They are able to equip their chamber vacuum sealers (found here) with a soft air option via an inert gas kit. Let me explain.

One of the reasons vacuum sealers are able to increase the lifespan of food is because the life giving oxygen air that feeds bacteria is removed. Oxygen makes up about 20% of the air that we breath. Minipack chamber sealers are capable of removing 99.9% of all air in the packaging. This also protects against freezer burn and other elements.

The inert gas kit allows for soft air packaging. Soft air packaging basically involves injecting nitrogen into the package after the oxygen has been removed. This method prevents the vacuum packaging from being drawn down tight around the product. This packaging method is commonly used for packaging potato chips and other delicate food products that would otherwise be destroyed. One reason this is referred to as a pillow pack is because of the pillow-like nature of these bags (such as potato chips).

Minipack chamber sealers can be outfitted with an inert gas flush kit. This is done in the factory, so be sure you order this feature up front when buying a machine for pillow pack purposes. The kit essentially consists of a gas flush nozzle that is set near where the sealing bar is located. This nozzle is inserted in the open end of the pouch where oxygen is removed and nitrogen is inserted.

Minipack chamber vacuum sealers can be built with a manual soft air option along with the gas flush kit. The soft air option helps prevent sharp objects from puncturing the pouch. It is adjustable to accommodate a variety of products and allows for softer bag placement around the product. As mentioned earlier in the article, this is especially nice for a “special look” for retail sales or for delicate product packaging.

There are a few things you will need for the inert gas kit that will not come with the Minipack vacuum sealer. This includes:

  • The Nitrogen Tank
  • The Regulator
  • Necessary Hosing
  • Proper Connections & Fittings

In order to get the nitrogen tank fitted to your vacuum sealer, you will probably want to contact a gas tank company or welding company in your local area. They should be able to help get your vacuum sealer properly set up. If you are unable to locate someone in your local area, we are certainly more than happy to help. Contact us at 1-800-658-8788 for help finding a company that can outfit you with a nitrogen tank and necessary fittings.

We recently helped a customer with their purchase of an MVS 45X (found here) that was outfitted with an inert gas kit and manual soft air option. The nitrogen tank, regulator, hosing and fittings ended up costing less than $300 with labor (including a 5 foot tank), so it really isn’t too bad for commercial packaging purposes. This was through a company called National Welders out of South Carolina.
