Extrusion lamination is one of the most common manufacturing routes, where molten LDPE is extruded onto aluminum foil and bonded under controlled nip pressure and cooling. Adhesive lamination is also used in multi-layer systems when specific bond performance, chemical resistance, or low-odor requirements are needed.

One of its key advantages is good strength-to-weight performance. Compared with commercially pure aluminum, 3004 provides higher strength while maintaining sufficient ductility for honeycomb-core processing.

The main application is pharmaceutical PTP blister packaging for tablets, capsules, and other solid dosage forms. The aluminum foil acts as a protective barrier, helping shield sensitive products from moisture, oxygen, and light during storage and transportation.

8011 aluminum alloy offers a useful balance of strength, ductility, corrosion resistance, and surface quality. In the H18 temper, the foil has a hard condition that provides higher strength and dimensional stability, making it suitable for high-speed coating, printing, slitting, and blister packaging processes.
