Aluminium foil sheet, which is used in the manufacture of screw cap systems for bottles and other containers, is one of the main products in the aluminium packaging market. Aluminium property of being impermeable to gases and light, as well as the fact that it can be easily formed and decorated, make it a material of choice for closure applications.
Aluminium property of being impermeable to gases and light, excellent deep-drawing capabilities and lacquer adhesion, Aluminum foil sheet be widely used in :
1. the caps for long neck wine bottles, extremely deep drawn and decorated closures, plus a range of pilfer proof caps for beverage bottles, soft drink, juice, isotonic beverage, energy beverage, and other products,
2. For heat sealing with PVC,PVC/PVDC or alu alu foil to pack medical such as capsules,pills or tablets.

Advantages
Aluminum foil is popularity as a packaging material is due to its excellent impermeability to water vapor and gases. It also extends shelf life, uses less storage space, and generates less waste than many other packaging materials.
Aluminum foil is tasteless, odorless, nontoxic, and hygienic. A special advantage of annealed foil is that it is substantially sterile because of the temperature of annealing. Because it is an efficient reflector and low emitter of radiant heat, aluminum foil is employed for packaging where the thermal insulating properties imparted by these characteristics are advantageous.
