The material structure of packaging aluminum foil

Many people think that packaging aluminum foil is not a packaging bag made of aluminum foil? Then the price of aluminum foil is fine, why buy special aluminum foil for packaging and spend a higher price? In fact, this involves a material structure problem of packaging aluminum foil. In addition to the packaging aluminum foils made of pure metal, there are other types of structures made of aluminum foil for packaging materials combined with other materials. Therefore, in contrast, these materials can be specifically applied to the packaging of a certain product, and this complex process will also make some packaging foils more expensive.

Then let's take a look at the packaging aluminum foil of the composite structure. Some aluminum foil bags are composed of aluminum foil material and CPEI and NY film material. The outer layer is NY film, and NY is polyamide and nylon. Such an outer layer has high mechanical strength, high softening point, heat resistance, low friction coefficient, not easy to wear, and good electrical insulation. The inner layer of the aluminum foil bag is CPE film, and CPE is chlorinated polyethylene, which is obtained by chlorination of high-density polyethylene. The advantages of packaging aluminum foil inner layer CPE include chemical stability, aging resistance, flame resistance, cold resistance, weather resistance, free coloring, chemical resistance, ozone resistance and electrical insulation, as well as good compatibility and processability. And the middle layer, of course, is aluminum foil. AL refers to aluminum alloy. Aluminum is non-magnetic, has good reflective properties, can reflect visible light, has good ductility, and can also reflect ultraviolet rays. The packaging aluminum foil is usually an aluminum film coil. In this way, aluminum foil bags can be widely used in anti-static, moisture-proof and vacuum packaging of industrial electronic components, optical optoelectronic products, hardware, food, etc.
