Protective coating Transparent high barrier PET AlOx film (PET-AlOx-T)
Product description
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
