Put the re-purpose  part of reuse, recycle, re-purpose to use with this simple homemade bag closer that will seal up the bag and keep your food fresh longer.

Smaller mouthed bottles are great for thin wrappers, like bread bags. Larger mouthed bottles work well for thicker bags. Plus, this works in both the refrigerator and freezer.

This trick doesn't work with every kind bag but it's good for most basic sealing and storage needs. It can also be used on bags that store things besides food.

Remember, the part of the bottle you don't re-purpose can usually be recycled, which is even better.
