The next time you empty a plastic milk or water jug, rather than recycle it, transform it into a reusable to-go container for sandwiches, wraps, salads and snacks. You only need a few household supplies and a few minutes. Image from Creme de la Craft.
Once you clean your empty water or milk jug (and you should definitely clean them first), cut a half moon on three sides. On the side of the jug opposite the handle, cut all the way up to the top to make the lid of the container. The bottom of the jug will be the bottom of the container and the sides of the jug will fold down as flaps to cover your food. If the flaps won't fold down, cut slits in each corner of the container to make the flaps longer and more flexible.
To secure the container, you can sew a button on the top, or use string to tie a reclosable knot through slits in the top. Best of all, these containers are easy to clean. Keep in mind though, they're reclosable and sturdy, but they aren't sealed. Stick to packing food that won't leak.
