Aluminum foil is soft, light, beautiful and easy to process. It is one of the most commonly used materials in modern packaging. Because aluminum foil is easy to form pinholes during packaging and use, which reduces its barrier performance, aluminum foil is often used as a composite material with paper, polymer or other metal sheets.
Aluminum foil composite material can greatly improve the barrier properties of packaging, improve the mechanical strength and mechanical properties of aluminum foil, which is especially suitable for the production of composite flexible packaging and packaging lining of food, medicine, cosmetics, cigarettes,etc.
At present, there are many varieties of this type of aluminum foil composite paper, and different papers can be used according to different needs. In particular, the combination of aluminum foil and paper for cigarette packaging has accounted for 40% to 50% of the consumption of aluminum foil.
The use of aluminum in the tobacco packaging industry is mainly the aluminum foil for the cigarette lining paper, the aluminized layer on the cigarette case, and the bronzing of the tipping paper.
The largest amount of aluminum in cigarette packaging is aluminum foil lining paper. The aluminum foil lining paper is a composite paper of thin paper and aluminum foil. The aluminum foil thickness is 0.006mm to 0.007mm. The general choice is 0.006 mm aluminum foil with O temper.
