Wow! What an interesting concept! My kids pack their own lunches for school. They use stainless steel containers and reusable sandwich wraps, which are machine washable. By doing so, they don’t add to all the waste which is generated by some of their other classmates, who use lots of pre-packaged foods such as juice boxes and Lunchables.
Of course, there is always cafeteria food. Yum!
Be sure to label your kids’ reuseable containers. Over time, they have a habit of ending up in the school lost and found.
