Soft Aluminum Foil For Pharmaceutical
Aluminum foil has a wide range of uses. The thickness of medical aluminum foil is between 0.006-0.02 for compounding, coating, and printing. The aluminum foil and other raw materials have better moisture resistance than other raw materials. At the same time, aluminum foil has good heat insulation performance. The most important thing is aluminum. Poisonous, non-adsorbing, it can minimize the growth of bacteria.
Flexible packaging aluminum foil is a bag container made of flexible composite packaging materials. The emergence of aluminum foil for flexible packaging has greatly improved the mechanization and automation level of the food and beverage industry, and has accelerated the modernization and socialization of people's dietary life. In developed countries, aluminum foil for flexible packaging has become one of the main packaging forms for food and beverages, replacing canned and bottled packaging within a certain range. In recent years, China's flexible packaging market has also developed rapidly, and different processes such as dry compounding, hot-melting compounding, and extrusion compounding can be used according to the different uses of flexible packaging. Flexible packaging aluminum foil not only has the effect of moisture-proof and fresh-keeping, but also can print various patterns and characters. With the improvement of people's living standards, flexible packaging aluminum foil still has a lot of room for development.
Soft Aluminum Foil For Pharmaceutical is currently more commonly used aluminum-plastic composite film, such as cellophane and aluminum foil and polyethylene composite (PT/AL/PE), polyester and aluminum foil and polyethylene composite (PET/AL/PE), namely aluminum foil It is laminated or extruded with plastic film and is composed of a base layer, a printing layer, a high barrier layer, and a sealing layer. The base layer is outside, the heat sealing layer is inside, and the high barrier layer and printing layer are in the middle. The base material is required to have excellent mechanical properties, good gloss printability, good transparency, high barrier properties, safety, non-toxicity, and no heat sealability. Typical materials are polyester (PET), cellophane (PT) and cellophane coated with PVDC. The high barrier layer should have good gas barrier performance and moisture resistance, no bacteria and microorganisms, good mechanical properties, a certain degree of elongation, cold and heat resistance, safe and non-toxic. Its typical material is soft aluminum foil. However, this soft aluminum foil is opaque, does not rust itself, and has strong shading properties. If a transparent strip-shaped packaging film is required, PVDC should be used as the high barrier layer material. PVDC is used as a high barrier layer material, and its biggest feature is its excellent barrier performance to gas and water vapor. The sealing layer is the inner layer of the strip-shaped packaging film, which has excellent heat-sealability, chemical stability, safety and hygiene, and generally uses low-density polyethylene materials
