Sandwich bags, along with a multitude of other types of plastic bags such as grocery bags, cereal bags that don’t tear like paper, bread bags, dry cleaning bags and other food storage bags, are categorized as “film” or “plastic film”. Film is usually either Plastic #2 or #4 made of polyethylene, the same plastic that makes milk jugs and margarine tubs are made from. Film, in itself, is recyclable, but the recycling center must have the means to provide such a service.
