Alumina Series
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.

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.
