Categories: Polymer; Thermoplastic; Polyester, TP; Polyethylene Terephthalate (PET); Polyethylene Terephthalate (PET), Unreinforced

Material Notes: VersaTray plastic 12822 is a polyethylene terephthalate resin designed for use as a base resin for crystallized PET (CPET) food trays and other high temperature food packaging applications. CPET food packaging made from VersaTray plastic is dual ovenable, which means it can be used in either a microwave or a conventional oven. So it gives you the most heating and cooking flexibility. You can heat, bake, warm or brown your meal in either appliance. And, CPET trays are also freezable.
