PET-AlOx-DTZ is a coated transparent barrier film for demanding retort packaging. It is intended for customers who need strong oxygen and moisture protection while keeping the product visible.

The brochure classifies PET-AlOx-DTZ as printable and 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 ≤ 0.5 cc/m²·day (ASTM D-3985), WVTR ≤ 0.5 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 film for high-barrier retort packaging.
• OTR ≤ 0.5 cc/m²·day and WVTR ≤ 0.5 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.

• High-barrier retort packaging for steamed food, medicine, cosmetics and precision electronic products.
• Transparent packaging where product visibility is required together with oxygen and moisture protection.
• A barrier option when customers are 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.
