What is the material of aluminum foil sealing film?

‌The material of aluminum foil sealing film is mainly aluminum foil. ‌

Aluminum foil sealing film is a packaging material with aluminum foil as the main base material and processed by special technology. It has excellent barrier properties, good light-shielding properties and excellent corrosion resistance, and can effectively prevent external factors such as oxygen, water vapor, and light from invading the packaged items. Aluminum foil has excellent light-shielding properties, which can block more than 99% of ultraviolet rays and visible light, and reduce the chemical changes of packaged items due to light. At the same time, aluminum foil has good corrosion resistance, can resist the erosion of chemical substances such as acids and alkalis, and protect packaged items from external pollution. In addition, aluminum foil sealing film also has the characteristics of waterproof, dustproof, moisture-proof, and corrosion-resistant, with high tensile strength and long service life. Therefore, it is widely used in daily packaging in food, medicine, electronics, electromechanical, hardware and other industries. ‌

The composition of aluminum foil sealing film also includes other materials, such as heat sealing layer, weak adhesive layer, cardboard elastomer, etc. The combination of these materials makes the aluminum foil sealing film have sealing performance, variability and anti-counterfeiting effect, preventing the volatilization and pollution of the contents of the product, and no odor. This composite material is more commonly used in packaging container sealing, simple operation, and a wide range of applications. It can be used in beverage bottle sealing, glass bottle sealing and many other occasions.
