Key Product Types
1. Household Aluminum Foil
This is the most common type. It comes in soft temper (O). The thickness ranges from 0.01 mm to 0.02 mm. It works well for food wrapping, baking, and storage. The foil tears easily and conforms to food shapes.
2. Pharmaceutical Grade Foil
Pharmaceutical aluminum foil uses H18 temper. Thickness typically falls between 0.016 mm and 0.05 mm. This foil must meet strict cleanliness standards. It blocks moisture, oxygen, and light. Common uses include blister packs for tablets and capsules.
3. Container Foil (H24 Temper)
Container-grade 8011 aluminum foil uses H24 temper. Thickness ranges from 0.03 mm to 0.1 mm. This type withstands deep drawing processes. It forms rigid food containers and trays. The material resists cracking during forming operations.
4. Lidding Foil
Lidding foil seals yogurt cups, juice bottles, and pharmaceutical containers. It comes in H16 or H18 temper. Thickness varies from 0.02 mm to 0.04 mm. The surface accepts heat-seal lacquers for secure closure.
5. Laminate Base Foil
This type serves as the barrier layer in multi-layer packaging. It uses O or H22 temper. Thickness ranges from 0.006 mm to 0.02 mm. The foil bonds well with plastic films and paper.
