Application
AlOx PET coating gives the transparent ALOx films a high barrier property. Transparent AlOx films are suitable for food, medicine, cosmetics, precision instruments, and other packaging. ALOx barrier films are microwavable and provide a long food shelf life. According to the function of the coating type, it can achieve water-boiling, retort, high barrier, and microwave heating. It can be replaced high barrier structures like K (PVDC) coating, BOPA, EVOH, and extrusion film.
