Sustainable Food Storage

These compostable quart-size bags hold 25 pieces made from plant-derived PLA, PBAT and cornstarch. They suit households that want leak-free freezer storage and a reusable alternative to single-use plastic. The BPI-certified material breaks down in commercial composting facilities where available.

Leak-Proof Freezer Performance

The ultra-tight slide seal keeps liquids, soups and sauces contained through freeze-thaw cycles without bursts. Sturdy thickness resists punctures from ice crystals or sharp edges while preventing freezer burn on meats, fruits and prepared meals.

Reusable Design Advantage

Each bag rinses clean for multiple uses, keeping sandwiches and snacks fresh in lunch boxes over several cycles. The grippy zipper opens and closes reliably even with cold or wet hands. No bundled accessories or software are included.

Questions about this item

How do I open and close the slide zip on these 7 x 7.4 in bags without missing the track?

Pinch the grippy tabs on the slide zip, pull apart to open, then run the slider firmly across the top until it clicks shut; the wide 7 in opening gives room to align the tracks before sealing.

How many times can each quart bag be rinsed and reused before the PLA + PBAT + cornstarch material breaks down?

The plant-based film is designed for several wash-and-reuse cycles; retire a bag once the slide zip no longer clicks securely or the walls feel thin.

What is the maximum freezer temperature these BPI-certified compostable bags can withstand without becoming brittle?

They are rated freezer-safe for standard home freezers; avoid direct contact with dry ice or temperatures below -18 °C to keep the seal flexible.
