PET-AlOx-TZ is a coated, printable AlOx barrier film for heat-processed flexible packaging. It gives customers a transparent option where opaque metallized film or aluminum foil would block product visibility.

The brochure classifies PET-AlOx-TZ as retortable below 121°C for 30 minutes. Retort performance must still be validated in the finished laminate and package.

Brochure reference values: 12 μm thickness, OTR ≤ 0.8 cc/m²·day (ASTM D-3985), WVTR ≤ 1.0 g/m²·day (ASTM F-1249), light transmittance ≥ 89%, AlOx-side surface tension ≥ 52 mN/m and PET-side surface tension ≥ 42 mN/m.

• Printable transparent AlOx barrier film for retort applications.
• OTR ≤ 0.8 cc/m²·day and WVTR ≤ 1.0 g/m²·day, using the test methods listed in the brochure.
• Light transmittance ≥ 89%.
• 12 μm standard thickness; tensile strength ≥ 170 MPa in MD and TD; elongation at break ≥ 80% in MD and TD.
• Retortable below 121°C for 30 minutes.
• AlOx-side surface tension ≥ 52 mN/m; PET-side surface tension ≥ 42 mN/m.

• Retort packaging for steamed food, medicine, cosmetics and precision electronic products.
• Example structures shown in the brochure: PET-AlOx-TZ (printing) / RCPP, or printed PET / PET-AlOx-TZ / RCPP.
• A transparent barrier option when evaluating alternatives to aluminum foil, conventional metallized film, K-coated film or SiOx film.
• Final printing, lamination, barrier and retort performance should be validated in the customer's packaging structure.
