Vacuum Sealer Bags

Airtight bags for long freezing and sous-vide

Textured bags made for a vacuum sealer that lock out air for long-term freezing and sous-vide cooking. The channels let the machine pull a full vacuum and seal tight. Leave extra room at the top for a clean weld, and label before sealing.

Vacuum sealer bags are specially textured plastic pouches designed to work with a vacuum-sealing machine, which sucks out the air and heat-welds the open end shut. The embossed channels on one side are the secret — they keep air pathways open so the machine can pull a full vacuum even where the bag would otherwise pinch closed. By removing virtually all air, they push freezer life from months to a year-plus and create the airtight, water-safe pouch that sous-vide cooking requires.

Types & varieties

Embossed bags

Textured channels for clamp-style (external) vacuum sealers — the home standard.

Chamber bags

Smooth, cheaper bags for commercial chamber sealers (won't work in a clamp sealer).

Roll stock

A continuous roll you cut to any length, sealing one end yourself — cheapest per use.

Getting a clean seal

Leave several inches of empty bag above the food so the machine has a clean, dry strip to weld. Wipe any moisture, fat, or crumbs from the seal zone — they prevent a solid weld and let air creep back in. For wet or saucy foods, freeze them first or use the machine's moist setting so liquid isn't pulled into the seal.

Pre-freeze wet foods so liquid doesn't get sucked in

Sous-vide and freezing

For sous-vide, vacuum bags hold food tight against the water for even cooking and won't leak at low temperatures; confirm the bag is rated for the temperature you're using. For the freezer, the full vacuum is what beats freezer burn for the long haul. Label before sealing — you can't write on a sealed pouch easily.

Tips & pitfalls

Leave plenty of empty bag above the food so the sealer gets a clean weld.
Keep the seal area dry and free of fat — moisture ruins the weld.
Match the bag type to your machine: embossed for clamp sealers, smooth for chamber sealers.
Pre-freeze soups and sauces before sealing so liquid isn't pulled into the seal bar.
Label and date before sealing; writing on a finished pouch is awkward.

Good to know

Material: Multi-layer plastic, embossed/channeled on one side
Formats: Pre-cut bags or a continuous roll you cut to length
Heat safe to: Food-grade and sous-vide-rated (commonly to ~90 C); check the brand
Freezer life: Extends storage to a year or more vs. months
Reusable?: Sometimes — wash and re-seal non-meat bags, losing length each time
Price range: Moderate (rolls are economical)
