Aluminum foil is widely used in automobile manufacturing, textile, electronic industry, electromechanical industry, aerospace industry, packaging industry, construction industry, shipbuilding industry, etc. it is an important industrial raw material.
At present, China can consume 161300 tons of aluminum foil every year. The second is cigarette foil. The annual consumption of cigarette foil in cigarette packaging reaches 35000 tons, accounting for 60% of the total consumption of double zero foil; Third, decorative foil, which is used for heat insulation, moisture-proof and decorative materials in the construction industry. At present, China's construction and household appliance industries have formed an upsurge in the application of decorative foil; The fourth is cable foil, which uses the tightness and shielding of aluminum foil as the shield of cable. The consumption of aluminum foil of the above four varieties accounts for more than 70% of the total consumption of aluminum foil in China. Pharmaceutical foil, electronic foil, automotive foil and flexible packaging foil have also become important consumption growth points in the aluminum foil market.
In addition to cigarette packaging, the application of aluminum foil in packaging industry mainly includes: aluminum plastic composite bag, medicine aluminum foil blister packaging and chocolate packaging. Some beer bottles are also wrapped in aluminum foil.
Medical blister packaging includes medical aluminum foil, PVC plastic hard sheet, heat sealing coating and other materials. Medical aluminum foil is a sealing material sealed on plastic hard sheet. It has the advantages of corrosion resistance, impermeability, heat resistance, moisture resistance, light resistance, high temperature sterilization and so on. The thickness of medical aluminum foil is generally 0.02mm, which is composed of protective layer, ink printing layer, substrate and adhesive layer. Due to the high cost, all aluminum blister is mainly used for some expensive drug packaging.
In addition to making soft cans, aluminum plastic composite bags are also widely used in small food, fried food and so on. In addition, the aluminum-plastic composite bag can pack drug tablets or traditional Chinese medicine powders. Due to its excellent barrier properties, aluminum-plastic composites are also used in ordnance and military packaging.
