Huhtamaki introduces new self-venting film with multiple PP (polypropylene) and CPET (Crystalline polyethylene terephthalate) tray options for the Steam Chef line for ready meal packaging. With no flaps or piercing required, the self-venting easy peelable lidding film enables cooking with the steam pressure regulating technology. From freezer or fridge to microwave, Steam Chef allows vapor to release without rupturing the films.
