Freezer Bags vs. Storage Bags: Which One Do You Need?

Not all resealable plastic bags are created equal. Here’s how to pick the right one so your food stays fresher longer.

What are freezer bags and storage bags used for?

Reach for a freezer bag when you’re stashing something for the long haul. Freezer bags are made with thicker plastic to withstand the cold, help prevent freezer burn, and keep flavors from mixing with other items.


Reach for a storage bag when you need a quick, everyday solution. Storage bags are your go-to for packing lunches, storing leftovers in the fridge, and organizing snacks. They’re lightweight and flexible, perfect for grab-and-go.


The bottom line: Freezer bags help fight the cold, while storage bags handle the day-to-day. Keep both reusable plastic bags on hand, and you’re covered no matter what’s on the menu.

The differences between freezer bags and storage bags

  • Thickness and durability – Freezer bags bring extra-thick plastic to stand up to the cold and help resist punctures, while storage bags are built for easy, everyday use in the fridge and pantry.
  • Moisture and odor barrier – Freezer bags help lock in freshness, keeping moisture and odors from sneaking in (or out) so flavor and texture stay put.
  • Best use – Freeze meat, fish, and produce with freezer bags. Grab storage bags for snacks, sandwiches, pantry organizing, and short-term fridge stays.

What’s the difference between freezer bags and storage bags?

The main difference comes down to the material. Freezer bags are made with thicker, more durable plastic that helps resist rips and punctures while protecting against freezer burn, helping food stay fresher for longer. Storage bags use a lighter material, better suited for everyday fridge and pantry storage.

Why Freezer Bags Are Better for the Freezer

Storage bags can technically handle freezer duty, but freezer bags do it better. Their thicker, more durable material is designed to perform well in cold settings, helping to guard against freezer burn and helping to keep meat and produce fresher for longer.

Thickness and durability

Freezer bags are made with thicker plastic than storage bags, giving them extra durability to help resist punctures and wear. That added strength makes them the better choice for foods with bones or jagged edges, and for liquids.

Seal quality

Both storage and freezer bags offer sliding zipper seals in quart, half-gallon, and gallon size options. You’ll also find easy press-to-close, double-zipper seals available across both types.

Available sizes

Both freezer bags and storage bags come in quart, half-gallon, and gallon sizes, so you’re covered for most everyday needs. Storage bags round things out with a few extra options too, like snack bags, sandwich bags, and jumbo 2.5-gallon bags for whatever life throws your way.
