A great alternative to traditional, single-use plastic bags. Simply wash and reuse. These bags are made from food-grade PEVA, a sustainable material known to be better for the environment. Great for packing lunch, freezing leftovers, or marinating BBQ meats. The full length zipper along the top creates an airtight seal, so full flavor and taste stays intact longer. They roll up nicely too, taking up less room than a container. They store easily in a fridge, freezer, or lunch bag. While perfect for providing leak-proof food storage, they are also suitable for other uses: goodie bags for the kid or a travel bag to take with you while on vacation.
