The Resource for Chamber Vacuum Sealing and Flat Pouches

There's a lot of confusion online between channel bags and flat vacuum pouches — and between the machines that use them. ChamberSealers.com exists to clear that up, especially for people who are moving from a home sealer to a commercial setup for the first time.

What This Site Covers

Chamber sealers are a fundamentally different category of machine from the external vacuum sealers you see at warehouse stores. They use smooth, flat pouches — no embossed ribs, no channels — because the entire chamber is evacuated rather than pulling air through the bag itself.

This site covers how chamber sealers work, what kinds of flat pouches and vacuum bags are used with them, the difference between chamber and external sealers, and how to source the right pouches for your operation.

The Flat Pouch Difference

When someone searching for vacuum bags finds their way to a channel bag product and buys it for a chamber sealer, it's a frustrating mistake. Channel bags work fine in external sealers — but a chamber machine doesn't need them, and using smooth flat pouches is both cheaper and more reliable.

The reverse is also true: if you try to use flat pouches in a consumer-grade external sealer, you'll get a poor seal or no seal at all. The machine can't pull air through a smooth surface.

Knowing which bag goes with which machine is the whole ballgame. That's what this site is about.

Pouches and Equipment

ChamberSealers.com is connected to BCU Plastics Packaging Supplies, a US-based supplier of vacuum pouches, barrier bags, and packaging equipment. If you need flat chamber pouches — in any size, mil thickness, or material spec — they're a good first call.
