BOPP is biaxially oriented polypropylene and PET is polyester. Self-wound BOPP is generally used to provide label protection for the ink and substrate and enhance the look with a gloss or matte appearance. Self-wound PET is generally used for a more challenging label application which calls for more durability, abrasion resistance, higher heat resistance, UV stability or where a stronger overlaminate is needed. The PET also enhances the look with a gloss or matte appearance.
