PET-AlOx-T adds a protective top coating to a transparent AlOx-coated BOPET base. It is intended for customers who need a printable barrier web for lamination.

The brochure lists this grade as printable. It should not be described as pasteurizable or retortable; heat-processing requirements must be validated separately.

Brochure reference values: 12 μm thickness, OTR ≤ 0.5 cc/m²·day (ASTM D-3985), WVTR ≤ 1.5 g/m²·day (ASTM F-1249), light transmittance ≥ 89%, AlOx-side surface tension ≥ 45 mN/m and PET-side surface tension ≥ 42 mN/m.

• Top-coated transparent AlOx film with printable surface performance.
• OTR ≤ 0.5 cc/m²·day and WVTR ≤ 1.5 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.
• AlOx-side surface tension ≥ 45 mN/m; PET-side surface tension ≥ 42 mN/m.
• Designed for microwave-heating applications and metal detection, subject to validation of the complete package structure.

• Printable barrier laminates for dried foods, medicine, cosmetics and electronic products.
• Example structure shown in the brochure: PET-AlOx-T (printing) / CPP or PE.
• A transparent barrier option when evaluating alternatives to K-coated films, BOPA, EVOH, co-extruded films, SiOx, aluminum foil or conventional metallized film.
• Final printing, lamination, barrier and heat-processing performance should be validated in the customer's packaging structure.
