The Best Reusable Food Storage Bags: 6 Compared (and One to Skip)

RBE top pick

Stasher Half Gallon Bag

Check price on Amazon See why it wins Compare all

Stasher publishes the most complete spec sheet here, from platinum silicone and a leak-free seal to capacity, tare weight and a 425°F oven rating. Zip Top's stand-up bags are the easiest to fill and to clean in a dishwasher, which makes them the better choice for daily lunches.

Reusable food bags replace zip-top plastic bags for leftovers, lunches and the freezer, and the good ones last for years. The big split is material: platinum silicone handles heat, from the microwave to the oven, while plastic and fabric bags are lighter and cheaper but must stay away from heat. After that, the seal, the capacity and how you clean them decide which one you keep reaching for. We compared six popular bags.

How we judged the field

Five things decide whether a reusable food bag earns a place in the drawer. Material comes first, because it sets the heat limits: platinum silicone goes from freezer to oven, while PEVA plastic must stay cool. The seal decides whether you trust it with soup or marinade. Capacity and shape decide what fits and whether the bag stands up while you fill it. Cleaning decides whether you will actually reuse it. And the clarity of the listing matters, because a brand that names its silicone grade and seal design is easier to trust.

The field splits into silicone bags, which cost more and handle heat, and PEVA bags, which are light and cheap. We picked three silicone bags, one popular PEVA bag, a thick reusable plastic zip bag and a zippered fabric snack bag, and compared them only on what each brand publishes. W&P’s page was behind a password gate, so the Porter’s details could not be confirmed.

The Stasher Half Gallon Bag is the pick because Stasher tells you exactly what you are buying. It is food-grade platinum silicone with no BPA, BPS, lead, latex or phthalates, closed by a patented Pinch-Loc seal that Stasher calls leak-free. The spec sheet lists a 64 fl oz (1893 mL) capacity, dimensions of 8.5 x 10.25 x 1.5 inches and a tare weight of 4.2 oz. It is dishwasher, microwave, freezer and oven safe up to 425°F, and Stasher markets it for sous vide, holding two strip steaks. Returns are free within 30 days. The cautions are real but small. Stasher describes the seal as leak-free rather than airtight, and some owners report air working back in. Strong foods can leave temporary stains or smells, and Stasher asks you not to turn bags inside out, which makes hand washing the corners harder. For freezing, leftovers and cooking, it is the bag to buy.

The Zip Top Bag 3-Set is the buy for lunches and snacks. The bags are 100% platinum silicone, free of BPA, lead, PVC and phthalates, and the design is the selling point: they stand up, stay open while you fill them, and zip shut. Zip Top says the open, rounded interior actually gets clean in the dishwasher, which is the most common complaint about flat silicone bags. They are freezer, microwave and dishwasher safe. The gaps are in the listing. The set’s product page publishes no capacities or dimensions, there is no oven rating, and Zip Top makes no leakproof claim for the zip closure. The single Sandwich Bag is not currently sold on its own, so you buy a set. For packing lunches every day, where easy filling and easy washing matter more than cooking in the bag, it is the better choice.

The (re)zip Reusable Gallon Bag is the bag for the freezer and the pantry. It is made of PEVA, a plastic that (re)zip says is food-safe, BPA-free, lead-free and phthalate-free, and it is light, at 2 oz for a bag that holds 16 cups (128 fl oz). The double-lock closure is described as leakproof and airtight, and the bag is freezer safe, which makes it good for soups, marinades and bulk flour. The limits are all about heat. (re)zip says the bags are not meant for high heat and cannot go in the microwave, and dishwasher water must not exceed 102°F, so it recommends hand washing with a non-abrasive sponge. It also notes that some dish soaps can stiffen the seal, which a thin coat of olive oil fixes. If you freeze more than you reheat, it is a cheap, light and effective option.

The Smelly Proof Reusable Quart Bags are the closest thing here to a disposable zip bag that lasts. They are made in the USA from 3 mil clear film, or 4 mil black and 5 mil heavy duty versions, closed by a green TRILOK triple-track zipper that carries a lifetime warranty. Smelly Proof calls them freezer safe and dishwasher safe, and rates them for sous vide as long as the water stays at or under 190°F. They come in packs from 5 to 100, in flat, stand and fill, heavy duty and child resistant styles. The gap is the material. The page lists what the bags are free of, including BPA, phthalates, latex and PEVA, and says the materials are FDA approved and Type 7 recyclable, but never names the plastic. There is no microwave use, no boiling, and capacity is given only as 8.75 by 9.5 inch inside dimensions. For lunches, dry goods and moderate sous vide, they are a cheap upgrade from single-use bags.

The Bumkins Reusable Snack Bag is a different kind of reusable bag: a zippered fabric pouch rather than a sealed food bag. Each bag in the two pack is 7 by 7 inches, made of single-ply polyester with an embedded PU coating, which Bumkins says is the same waterproof fabric as its SuperBib and leaves no space between layers for crumbs or mould. You clean it in the washing machine or on the top rack of the dishwasher and let it air dry, and Bumkins lists third party testing against US CPSC rules for lead, phthalates, BPA, BPS and cadmium. The limits are stated plainly. The fabric is waterproof but the zipper is not, so Bumkins says the bags are not completely leakproof, and there is no guidance on heat, the microwave or the freezer. That rules out soup, marinade and leftovers. For a sandwich, a bagel or crackers in a school lunch, where washing in the laundry beats scrubbing corners, it does the job well.

The Porter Reusable Bag from W&P is a silicone bag that matches other W&P Porter containers, but we could not confirm enough about it to recommend it over the others. W&P’s product page was behind a password gate when we checked, so we could not verify its silicone grade, seal design, heat limits, sizes or washing instructions. Stasher and Zip Top both state platinum silicone and publish their care and heat guidance, and a bag that does not let you check those details is hard to trust with food. For the same job, the Stasher tells you more.

Who should buy which

• Freezing, reheating and sous vide: the Stasher Half Gallon Bag. Platinum silicone with a published 64 fl oz capacity and an oven rating up to 425°F.
• Daily lunches and snacks: the Zip Top Bag 3-Set. Stand-up platinum silicone bags that stay open to fill and come clean in the dishwasher.
• Big freezer and pantry batches: the (re)zip Reusable Gallon Bag. A 2 oz PEVA bag that holds 16 cups with a leakproof double-lock closure, kept away from heat.
• Replacing disposable zip bags cheaply: the Smelly Proof Reusable Quart Bags. Thick, made in the USA bags with a lifetime zipper warranty, if an unnamed plastic is acceptable.
• Dry snacks in a school lunch: the Bumkins Reusable Snack Bag, Large 2 Pack. Fabric pouches that go in the washing machine, for food that cannot leak.

Stasher Half Gallon Bag vs Zip Top Bag 3-Set: which should you buy?

The Stasher Half Gallon and the Zip Top Bag 3-Set are both platinum silicone and both dishwasher safe, but they are shaped for different jobs. The Stasher is a flat bag with a leak-free Pinch-Loc seal, a published 64 fl oz capacity and an oven rating up to 425°F, so it works for freezing, reheating and sous vide. The Zip Top bags stand up and stay open, zip shut, and have an open interior that is easier to clean, but Zip Top publishes no capacities and no oven rating.

Choose Stasher if your bags go in the freezer, the microwave or the oven, or if you want to know exactly how much they hold. Choose Zip Top if you pack lunches and snacks every day and want bags you can fill with one hand and clean in the dishwasher without scrubbing corners.

What to look for

• Named silicone grade: Platinum silicone is the higher grade; “premium silicone” without a grade tells you less.
• Heat limits: Silicone bags often go to 425°F in the oven; PEVA bags cannot go in the microwave at all.
• Seal design: Look for a described closure and a leakproof claim if you store liquids.
• Published capacity: A stated volume, such as 64 fl oz or 16 cups, makes it easy to choose the right size.
• Cleanability: Open, rounded interiors clean better in a dishwasher than tight flat corners.
• Free-from list: Check for BPA, lead and phthalates, and for PVC in plastic bags.

Our final take

For most kitchens, the Stasher Half Gallon Bag is the reusable food bag to buy. It is platinum silicone with a leak-free seal, a published capacity and a 425°F oven rating, so one bag covers freezing, reheating and cooking. For lunches and snacks, the Zip Top Bag 3-Set is easier to fill and to clean. The (re)zip Gallon Bag is a light, inexpensive choice for the freezer and pantry, as long as it stays away from heat. Skip the Porter Reusable Bag: without a confirmed silicone grade or a described seal, it tells you less than the alternatives.
