Rolls, Pre-Cut Bags or Zip Bags? Picking Vacuum Sealer Bags That Actually Fit

First, Which Machine Do You Have?

This is where most bag mix-ups start. Anova, which makes both kinds of sealers, explains that bags for suction (edge) sealers have a built-in texture that channels the air out, while chamber pouches are “completely clear and smooth.” And the key rule: “chamber sealer pouches are not compatible with edge sealers.” The other way around usually works: Anova says textured bags can go in a chamber sealer. Your machine’s manual has the final word.

Not sure what a chamber sealer is? Here’s how a chamber vacuum sealer works, in five steps.

Rolls or Pre-Cut Bags?

Rolls are the flexible choice. You cut exactly the length you need, so one long roll handles a single burger patty and a whole rack of ribs. If your sealer has a built-in cutter and roll storage, rolls are hardly any extra work.

Pre-cut bags are the quick choice. One side is open, three are sealed, so you fill, seal and you’re done. They’re handy for standard portions like a quart of berries or a gallon of chicken thighs, but you can’t make them longer.

My take: if you seal different things every week, start with rolls. If you always seal the same portions, pre-cut bags save a step.

How to Make a Bag From a Roll

1. Measure. Cut enough roll for the food, plus 3 extra inches. That’s FoodSaver’s instruction.
2. Seal one end first. Put one open end across the seal bar and seal it. Now you have a bag with one open side.
3. Fill it. Leave at least 3 inches of empty bag between the food and the open end. FoodSaver’s manual says this gives the bag room “to cinch tightly against the food.”
4. Keep the edge clean and dry. FoodSaver’s manual lists moisture or food along the seal as one reason a bag won’t seal; the fix is to wipe the inside top of the bag and seal again. My tip: fold the top of the bag back like a cuff while you fill it, so juice and crumbs stay away from the seal.
5. Vacuum and seal. Then label it with the food and the date.

What Size Do You Need?

• Width: the bag has to fit your seal bar. Among the sealers we looked at, the Nesco takes bags up to 11.8” wide, the FoodSaver comes with an 11” roll, the heavy-duty Weston seals bags up to 15” across, and the Avid Armor chamber sealer takes pouches up to 11” x 10”.
• 8” or 11”? My rule of thumb: narrow rolls for single portions and smaller cuts, wide rolls for bigger cuts, whole chickens and flat-frozen soup.
• Extra-wide bags need a sealer with a wide bar. Measure your machine before you buy them.

Reusable Vacuum Bags

Small pump systems use their own zip bags with a valve. The Zwilling Fresh & Save bags, for example, are listed as reusable, freezer safe and dishwasher safe, and microwave safe only without the vacuum seal. They’re nice for leftovers, cheese and meal prep, but they don’t work in a regular heat sealer.

Can You Reuse Heat-Sealed Bags?

Safety first: throw away bags that held raw meat, fish, eggs, unpasteurized cheese or greasy food. Never reuse those, even after washing. For all other bags, follow the bag maker’s instructions.

Some bags can be reused, and the makers draw the line clearly. FoodSaver, answering a customer question, says bags that held fruits, vegetables, breads and dry goods can be washed by hand (“Dry completely”) and reused, but bags that held “raw meats, fish, eggs or un-pasteurized cheese should be discarded after use”, and so should bags with greasy or oily food. Its FM2100 manual adds a handy trick: leave at least one extra inch of bag for each time you plan to reuse it, because every new seal costs a strip.

Being washable doesn’t make every bag reusable, so if your bag maker says single use, keep it single use. For smooth chamber pouches, Anova says the same in short: if the pouch held something dry and non-messy, slice off the sealed edge, wipe it out and use it again.

Microwave, Boiling and Sous Vide

This depends on the bag, not the sealer. The Amazon listing of the rolls we link to says they can be used in “freezers, refrigerators, microwaves, and boiling,” but not every bag is. That listing doesn’t mention sous vide, so for sous vide pick bags that say they’re made for it. Clemson Cooperative Extension’s advice applies here: “Follow the directions that come with the vacuum packages carefully.” If the bag or its packaging doesn’t say it’s made for cooking, don’t cook in it.
