Sourdough Bread Bag for Storage and Freezing

Waterproof TPU-lined bread bag. Keeps sourdough fresh longer and goes straight in the freezer. The smart alternative to disposable zip-lock bags.

If you bake in batches, freeze loaves, or want maximum freshness from your sourdough, this is the bag for it. The waterproof TPU lining seals in moisture completely — no drying, no freezer burn, no stale crust. Unlike a breathable canvas bag, this one locks everything in, which makes it ideal for longer storage and freezing.

Built from durable polyester with a sturdy carry handle and zipper closure. Fully washable and built for daily long-term reuse — a practical, eco-friendly replacement for the disposable zip-lock bags most people use for bread storage. The TPU lining is food-safe, BPA free, phthalate free, and heavy metal free.

Canvas vs TPU bag: the TPU bag is best for freezing and longer storage where you want a complete moisture seal. For everyday home storage where breathability matters, see our Canvas Bread Bag instead.

Care & Maintenance

Glass items (starter jar, jar lid): Dishwasher safe.

Silicone items (spatula, bowl scraper): Dishwasher safe. If silicone absorbs strong odours over time, soak briefly in diluted white vinegar to neutralise.

Wooden and bamboo items (whisk, bamboo scoop): Hand wash only — do not soak or put in the dishwasher. Dry immediately after washing. Condition occasionally with food-safe fractionated coconut oil to prevent drying and cracking.

Stainless steel only items: Dishwasher safe. Dry promptly to avoid water spots.

Canvas and fabric items (bread bags, cloth liners): Machine washable, cold or warm cycle. Air dry only — do not tumble dry.
