Quick answer

Reusable vacuum bags are worth it for leftovers, cheese, marinating, sous vide and short-term fridge storage. For long-term freezer storage of meat and fish, single-use heat-sealed bags are still more reliable. You can also safely reuse ordinary heat-seal bags that held dry goods, fruit or vegetables.

Two kinds of “reusable”

1. Reusable valve (zipper) bags

These have a zip closure and a one-way valve. You remove air with a handheld pump or, for some brands, an accessory hose. Examples include Zwilling Fresh & Save bags, FoodSaver zipper bags and Vesta reusable pouches. See best vacuum zipper bags.

2. Reused heat-seal bags

Regular embossed bags can be reused if you made them long enough: cut off the old seal, wash and dry the bag, and reseal. Each reuse costs about an inch.

Can reusable bags save you money?

Yes, if you use them for repeated, short-term jobs — weekly leftovers, cheese, marinating and meal prep. They cost more up front than single-use bags, so savings build up over many uses. Combine them with our other bag-saving tips.

Pros

  • Less plastic waste
  • Lower cost over many uses
  • Quick for leftovers and marinating
  • Many are sous vide-rated

Cons

  • Zipper seals can slowly leak in the freezer
  • Need a compatible pump or valve
  • Must be cleaned carefully after raw foods

Cleaning and safety

  • Wash with hot, soapy water (or on the top rack of the dishwasher if the manufacturer says it’s dishwasher-safe), turn inside out and dry completely.
  • Don’t reuse heat-seal bags that held raw meat, fish, eggs or greasy foods — they’re very hard to clean thoroughly.
  • Bags used for long sous vide cooks can weaken; check for cloudiness, cracks or thinning before reuse.
  • Keep the valve and zipper track free of food.

Frequently asked questions


Can you put reusable vacuum bags in the freezer?

Many are freezer-safe, but zipper seals are less reliable than heat seals over months. Use them for shorter freezer storage and check the manufacturer’s guidance.


Can you use reusable bags for sous vide?

Many reusable bags are rated for sous vide (for example, Zwilling Fresh & Save bags up to about 92°C). Check the temperature rating first.
