Aluminum foil in aluminum foil laminates is not only soft in texture, good in ductility, easy to process, but also lightweight and beautiful, easy to recycle, beneficial to environmental protection, and is one of the more commonly used materials in modern packaging. In addition, aluminum foil has high magnetic permeability, good magnetic absorption ability and electromagnetic wave shielding ability, and good heat resistance, so it is also commonly used in packaging of electronic equipment and semiconductor articles.
Because aluminum foil is easy to form pinholes during packaging and use to reduce its barrier performance, aluminum foil is often used as aluminum foil laminates with paper, polymer, or other metal sheets.
Practice has proved that aluminum foil laminates materials can greatly improve the barrier properties of packaging, improve the mechanical strength and mechanical properties of aluminum foil, and are particularly suitable for composite flexible packaging and packaging lining. They are widely used in the packaging of food, medicine, cosmetics, cigarettes and other commodities.
Aluminum foil laminates paper
Use the moisture, rust, gas barrier and corrosion resistance of aluminum foil to make it laminated with paper to become aluminum foil laminates paper, or use thermoplastic film as an adhesive to composite aluminum foil and paper together to form a multilayer composite paper. This composite paper combines the high barrier properties of aluminum foil with the folding resistance and impact resistance of paper, and becomes a high-performance packaging material. Most of the composite components in the material are non-toxic and odorless materials, which will not cause pollution to the contents and the human body, and it is easy to meet the hygiene and safety standards of packaging; at the same time, because the resin in it can be decomposed when heated to high temperature, the paper and aluminum foil are separated , Thus greatly improving the recycling of materials, reducing the waste of materials and the load on the environment.
Aluminum foil laminates soft film
Although aluminum foil is soft and foldable, it has low mechanical strength and poor sealing properties. By combining aluminum foil with high-strength, heat-sealable plastic films, you can obtain Aluminum foil laminates flexible packaging materials with excellent barrier properties, mechanical properties, and heat-sealing properties. , Widely used in food packaging, cooking bags, chemical and industrial product packaging and military supplies packaging.
Aluminum foil blister packaging material
The aluminum foil blister packaging material of medical and health products is also called blister packaging, referred to as “PTP” (Pressthronghpackaging). It is made of barrier plastic blisters and aluminum foil glued together. The blister packaging of medicines has good protection performance, fast production speed, low cost, small storage space, light weight and low energy consumption for transportation; it provides patients with a dose of medicine packaging, which is convenient and economical; There are written instructions printed on the aluminum foil, and the dispenser can avoid the occurrence of wrong medicines and mixed medicines in the distribution of various tablets.
