Applications of High Barrier Aluminum Foil in Flexible Packaging
Pharmaceutical Blister & Cold-Forming (Alu-Alu):
Recommended: 8021-O / 8079-O (40–50 μm). High tensile strength and deep-draw ductility for zero-leak moisture/light/oxygen barrier.
Retort Pouches & Aseptic Packaging (Liquid & Meat):
Recommended: 8079-O / 1235-O. Laminated with PET/NY/CPP for autoclave sterilization .
Electronic Vacuum & Anti-Static Bags:
Recommended: 8011-O / 1235-O. Shielding components from electrostatic discharge and moisture ingress.
FAQ
Q1:What wettability grade is guaranteed for lamination foil?
A:We guarantee Grade A wettability achieved through controlled annealing cycles. This ensures optimum adhesion with solvent-based, solvent-less, or extrusion-coated polyurethanes.
Q2:How do you guarantee barrier integrity against moisture and oxygen?
A:Pure aluminum foil is an absolute barrier down to microscopic levels. For foil gauges above 20 μm, it is virtually pinhole-free.
