The thickness of aluminum foil used for beverage packaging and food packaging bags is only 6.5 microns. This thin layer of aluminum repels water, preserves umami, protects against harmful microorganisms and resists stains. It has the characteristics of opaque, silver-white, anti-gloss, good barrier, high and low temperature resistance, oil resistance, heat sealing, shading, fragrance, no peculiar smell, soft and so on.
Aluminized packaging film is formed by coating a layer of metal aluminum on the surface of plastic film using a special process. It can be compounded with a variety of packaging materials with different functions, including: PET aluminized composite film, CPP aluminized composite film, etc. .
Advantages: The composite aluminized packaging film has good performance, good barrier properties, gas barrier, oxygen barrier, and light protection. It can be used on automatic packaging machines in the form of roll film, and can also be produced into packaging bags of different styles and printed with exquisite patterns.
Aluminized packaging bags are also called aluminum-plastic packaging bags. Aluminum foil packaging bags, as the name suggests, are packaging bags containing aluminum foil (pure aluminum) in the internal structure. In terms of performance of aluminum foil bags, the heat dissipation effect is better than that of aluminum-plated bags, pure aluminum bags are completely shading, and aluminum-plated bags have shading effects.

In terms of material, pure aluminum bags are pure aluminum with high purity and belong to soft materials; aluminum-plated bags are mixed with composite materials and belong to brittle materials. In terms of use, pure aluminum bags are more suitable for vacuuming, such as cooked food, meat and other products, while aluminum-plated bags are suitable for tea, powder, etc. In terms of cost, the unit price of pure aluminum bags is higher than that of aluminum-plated bags.
