I am now making a new type of reusable sandwich wrap. Using PUL fabric as a waterproof layer, sandwiches are kept fresh when wrapped up in these new reusable wraps. They are fastened with velcro and can fit sandwiches and snacks of all sizes. The PUL wipes clean after each use or the wraps can be thrown in the wash when they get really dirty. Still another way to deduce your ecological footprint.
