Unlike many suction, edge and external vacuum sealers, a chamber vacuum sealer houses the pouch and product within its chamber.

What Is A Chamber Vacuum Sealer?

Initially the pressure around us and inside the chamber are exactly identical (14.7 psi at sea level). Vacuum is created inside the chamber which in turn creates an airtight seal. Depending on the vacuum pump quality, up to 99.8% of the air is then removed from the chamber and vacuum pouch. Once all the air is extracted from the chamber, the vacuum pump shuts off and the bag is sealed.


Up to this point it will appear as though no air has been removed from the vacuum pouch. The pressure inside the pouch is equal to the pressure in the chamber. After the bag is fully sealed off, a valve will open to reintroduce air back in. The process will continue until pressure is equal to the environment outside the chamber. During these few seconds is when the bag will tighten up around the product. Finally, the vacuum sealed look will be observed in this final process.

Why Wouldn’t I Just Go With An Edge, Suction, Or External Vacuum Sealer?

Three very simple reasons why you should stay with a chamber vacuum.


1) Initial cost of an external may be lower, but chamber vacuum pouches are 3-5 times cheaper than the textured bags and roll.


2) Secondly, life span and longevity of a chamber vacuum sealer far exceeds the cheaper suction, edge and external vacuum sealers.


3) Lastly, your packaged goods will stay fresh much longer due to a chamber sealers ability to remove more air. Most chamber vacuum sealers will remove at least 99% of air, compare that to only 80% for even a good quality external vacuum sealer. Throw away those oxygen absorbers because there won’t be any oxygen left to absorb when using a high quality chamber vacuum sealer.
