PE, or polyethylene, is a versatile plastic with many uses. It can be soft and flexible as well as tough and strong. At IKEA we use PE for things like plastic bags, freezer bags, ice packs and chopping boards. A big reason why we like this plastic is that it’s recyclable and can also be made from renewable raw materials like corn and sugar cane. Look for the symbol with a triangle and the number 2 or 4 if you want to choose plastic made from renewable raw materials.
