Sandwich paper is a type of food-safe paper designed to wrap sandwiches, keeping them fresh and preventing mess. It’s typically grease-resistant and can come in various sizes and colors. To fold sandwich paper, place the sandwich in the center, fold the bottom up over the sandwich, then fold the sides in, and finally fold the top down. https://waxpapers.net/what-is-sandwich-paper-how-to-fold-sandwich-paper/
