Cold Form Foil 60 µm PVC 25 µm OPA 50 µm Alu foil 6-8 GSM HSL Key Properties
Excellent Barrier Performance
Due to the 50 µm thick aluminum foil layer, the barrier performance is significantly enhanced compared to the typical thickness (usually 45 µm or lower). It effectively prevents moisture, oxygen, and light penetration, protecting the pharmaceutical products inside from external environmental influences.
High Mechanical Strength
The PVC and OPA layers in the multi-layer structure provide excellent tear resistance and puncture strength, making the material resistant to damage during transportation and storage.
Heat Sealing Performance
The heat seal coating (HSL) ensures that the material bonds securely with other packaging materials, forming a reliable seal to prevent leakage or contamination.
Cold Form Foil 60 µm PVC 25 µm OPA 50 µm Alu foil 6-8 GSM HSL Applications
