Inside your refrigerator and pantry, plastic is everywhere. There’s plastic wrap, storage bags and bins, clamshell takeout containers, beverage bottles, and condiment tubs, of course. Plastics (synthetic polymers) are also a component of the multi-layer material that make up chip bags and encase granola bars. Tin, steel, and aluminum cans, like the type that might hold beans or a soda, are lined with plastic. Even many paper products, such as paper cups and frozen food trays, are coated in–you guessed it–plastic.
