Aluminium-oxide (AlOx) coated PET — metallized-level barrier without the metal. See-through so buyers watch the product, metal-detector compatible so lines keep scanning, microwave and 121°C retort ready.
Aluminium-oxide coating delivers OTR down to ≤ 0.5 cc/m²·day while staying optically clear (LT ≥ 88%) — replaces aluminium foil, VMPET, EVOH, and SiOx where the brand wants a see-through pack.
AlOx is non-metallic, so filled packs pass in-line metal detection — the one thing an aluminium-metallized film physically cannot do on a food line.
ES-T01 and ES-T03 withstand 121°C / 30 min retort; the whole family is microwaveable. Ready-meals, coffee, and pharma pouches you can heat in the pack.
Enables lighter, more recyclable structures with less foil. Complies with FDA, EU, REACH, RoHS and GB 4806.7 food-contact standards.
