Yes, please re-use your empty bags!
Given the nature of our product, the bags are pretty easy to wipe clean once you have finished with the product inside. We store our pre-cut fruit in these bags in the freezer, ready to add to smoothies or add to pancakes. As they stand up right, but are still flexible enough to be strategically placed in even a full freezer.
We also use them to store lettuce and herbs from our veggie garden in the fridge, to pack a snack for when on the road and to store sourdough!
They can be used for non-food purposes also, such as keeping your kids colouring pencils in, storing those loose nuts and bolts from furniture in the garage.
The possibilities really are endless.
