The applications of aluminum foil products in the packaging industry generally include: aluminum-plastic composite bags, pharmaceutical aluminum foil blister packaging, and chocolate packaging. Some high-end beer also has aluminum foil on the bottle mouth. Medicinal blister packaging also has medicinal aluminum foil, PVC plastic rigid sheet, heat-sealing paint and other materials. Medicinal aluminum foil is a sealing material that is sealed on a plastic hard film. It is generally non-toxic, corrosion-resistant, heat-resistant, moisture-proof, light-blocking, and capable of high temperature sterilization. The thickness of medicinal aluminum foil is usually 0.02 mm, which is composed of protective layer, ink printing layer, substrate and adhesive layer. Because of the low cost, all aluminum blister is generally used for some expensive medicine packaging.
In addition to the production of soft cans, aluminum-plastic composite bags also have certain uses in fried foods. At the same time, the aluminum-plastic composite bag can pack pharmaceutical tablets. Because of its excellent barrier properties, aluminum-plastic composite materials have a certain amount in the packaging of ordnance and munitions.
In the field of industrial packaging, aluminum foil packaging is a bright spot in the current development, and it is also a rapid growth point in the aluminum foil industry. Industrial aluminum foil bags are also called composite aluminum foil bags, which have good characteristics such as anti-static, anti-oxidation, and vacuuming. Under the premise of the rapid development of electronic products in recent years, aluminum foil bags are indispensable electronic packaging bags in the electronics industry, especially the production and production of highly sensitive electronic components.
