Key features & specs

How it compares

Compared to traditional Ziploc freezer bags, Matter's gallon bags are equally durable but slightly less flexible — they hold their shape well. They outperform many other compostable gallon bags (like those from Unni and BioBag) in freezer toughness, with fewer reports of tearing at low temperatures.

How to use it

1. Fill each bag no more than three-quarters full to allow for food expansion during freezing.
2. Squeeze out excess air before sealing to prevent freezer burn.
3. Flatten bags for uniform stacking and quicker thawing.
4. Label with a dry-erase marker directly on the bag or use a reusable tag.
5. When ready to dispose, place in a commercial compost bin — these will not break down in home compost.
6. Rinse lightly before composting to remove food residue if needed.
