Best Vacuum Sealer Bags for Sous Vide Cooking
Sous vide cooking puts vacuum sealer bags through a tougher test than freezer storage alone: the bag has to hold a tight seal while it sits in a hot water bath for hours, without leaching anything into the food or breaking down at temperature. Not every vacuum sealer bag is built for that — so before you seal your next sous vide bath, it's worth knowing what actually makes a bag sous vide safe.
What Makes a Vacuum Sealer Bag Safe for Sous Vide
A few things matter more for sous vide than for ordinary vacuum storage:
- Heat resistance: the bag needs to hold up to sustained water-bath temperatures without softening, warping, or releasing anything into the food.
- BPA-free material: especially important any time food sits in a heated bag for an extended cook.
- A strong seal: a weak seal is more likely to fail under the water pressure of a long sous vide bath than during a quick freezer seal.
- Puncture resistance: bags need to survive bones, sharp edges, and hours of submersion without a pinhole leak.
Our Pint, Quart, and Gallon embossed vacuum sealer bags are made of USDA-approved, BPA-free nylon/polyethylene and are listed as suitable for boiling as well as freezing — the combination sous vide cooking calls for.
Chamber vs. Embossed Bags for Sous Vide
Which bag style you need for sous vide comes down to your machine, the same way it does for any vacuum sealing job. If you're running a home suction-style sealer (FoodSaver and similar machines), you need embossed or channeled bags — the textured surface is what lets the machine pull air out through its nozzle. Chamber vacuum sealers use smooth bags instead, since the entire bag sits inside an airtight chamber during the vacuum cycle. If you're not sure which category your machine falls into, our Chamber vs. Embossed Vacuum Sealer Bags guide breaks down the difference in more detail.
For most home cooks doing sous vide, that means an embossed bag sized to your cut of meat, vegetables, or portion — our Pint, Quart, and Gallon sizes cover the range from single servings to larger batch cooks.
Choosing the Right Bag Size for Sous Vide
Sous vide works best when food sits in a single layer with minimal air pockets, so sizing the bag to the food (rather than sizing up "just in case") gives you faster, more even heat transfer:
- Pint (6" x 10"): good for single steaks, chicken breasts, or individual portions.
- Quart (8" x 12"): fits larger cuts, a few portions bagged together, or vegetables.
- Gallon (11" x 16"): best for batch cooking, larger roasts, or multiple portions at once.

Tips for Sealing Bags Before a Sous Vide Bath
- Leave enough empty bag above the food to get a clean, wrinkle-free seal — a seal that runs through food debris or liquid is more likely to fail in the water bath.
- Pat wet or marinated food dry where you can, since excess liquid can interfere with getting a full seal.
- Use the water displacement method if you're sealing without a machine that has a liquid-safe cycle: lower the bag slowly into water, letting the pressure push air out before sealing near the waterline.
- Check the seal line before it goes in the bath — a weak or incomplete seal is easier to catch and reseal now than after hours in the water.

FAQ
Can I use any vacuum sealer bag for sous vide?
No — the bag needs to be rated for boiling/heat exposure and made of a food-safe, BPA-free material. Check the product listing before using a bag for an extended water-bath cook.
Do I need special bags for sous vide, or will regular vacuum sealer bags work?
Bags that are already rated for both boiling and freezing, like our embossed Pint, Quart, and Gallon bags, are suitable for sous vide — you don't need a separate "sous vide only" product as long as the bag is heat-rated.
What size bag should I use for sous vide?
Size the bag to the food rather than sizing up — a closer fit means less trapped air and more even cooking. See our bag sizing guide for details.
