The AlOx coated PET film is coated with a transparent aluminum oxide layer on the surface of the BOPET film substrate by physical vapor deposition. It has good thermal stability, high temperature resistance, high strength and stable chemical properties.
Compared with co-extruded film, coated film and common metallized film, transparent AlOx metallized film is more environmental friendly, and has better barrier performance and printing performance. It provides better transparency visibility and printability, and is suitable for food packaging, medical products, medical materials, electronic products and other products that require higher barrier properties.
The product models are classified as follows:
PET-AlOx-020 : Normal AlOx PET Film
PET-AlOx-010 : High Barrier AlOx PET Film
PET-AlOx-T : Protective coating AlOx PET Film
PET-AlOx-TZ : Retortable AlOx PET Film
PET-AlOx-D01 : Ultra High Barrier AlOx PET Film
PET-AlOx-DTZ : Ultra High Barrier Retortable AlOx PET Film

◆ Widely used in Packaging barrier for food such as meat, cooked food, biscuits, candy, dried fruit, tea, coffee, chocolate, dehydrated food, seafood, flavors, etc. and electronics, daily chemicals, military products, pharmaceuticals, etc.;
◆ Replace the K (PVDC) coated film to greatly improve the barrier properties of the product and reduce the environmental pollution caused by PVDC. It can be boiled and steaming cooked. It has better visibility and no yellowing;
◆ Replacement of BOPA, EVOH and co-extruded film,. It can greatly reduce the cost, greatly improve the barrier performance of the product, and with better adaptability;
◆ In place of SiOx, it can greatly reduce the cost. It has softer hand feeling, better transparency, better processing performance and better environmental recycling treatment;
◆ Replacing the use of aluminum foil, the composite strength is higher, the cost is lower, it can be see-through, microwave heating, and can be detected by metal;
◆ It can replace the common metallized film, has better barrier property and higher composite strength. It can be seen through perspective, can be heated by microwave, and can be detected by metal.
