| PET-ALOX | Good mechanical properties Better barrier properties (moisture and gases) |
Widely used for high-barrier transparent packaging, as well as transparent high-barrier packaging for food and pharmaceutical products; can be pasteurized (three-layer structure). For the intermediate layer of the structure, when printing with PA, it is recommended that the composite structure be: PET/aluminum oxide/PA/PE. |
| Good composite adhesion and mechanical properties High barrier properties (moisture and gases) |
Widely used in high-barrier transparent packaging, as well as transparent high-barrier packaging for food and pharmaceutical products (used in three-layer structures, specifically the middle layer). For interlayer and PA printing, the recommended composite structure is: PEI-alumina-Z/PA/PE. Typically, after three-layer compounding, the barrier properties are enhanced. Oxygen resistance to moisture <0.5. |

Precautions: Caution:
1. The film must not have excessive elongation, and during co-extrusion, the temperature must not be too high, nor should the extruded coating thickness be too thick; otherwise, it could lead to cracking of the vapor-deposited aluminum layer.
2. The contents of the packaging must not be overly acidic, otherwise they may corrode the aluminum oxide.
3. The alumina layer should be kept from contacting the roller surface (especially hard rollers with grooves), and selecting an appropriate adhesive is beneficial for enhancing the bonding strength.
4. The above information is for reference only; actual verification shall prevail in specific applications.
