Aluminum foil, which has been fully annealed and softened after rolling, is soft and has excellent sealing and barrier properties. In modern society packaging, almost all products that require strict opacity and high barrier properties are made of aluminum foil composite materials. Package. For example, the rectangular box packaging of the milk we drink daily is a sterile package made of aluminum foil composite material; such as a cigarette box, in addition to the shiny outer shell made of aluminum foil composite material, there is also an aluminum foil paper inside to keep The aroma of tobacco; food packaging such as chicken essence and sucking ice is also a soft package made of aluminum foil composite materials... Let's sort out some of the common aluminum foil packaging and aluminum foil composite packaging in our lives.
Aluminum-plastic composite cans are not only suitable for holding machine oil, but are also high-quality packaging materials for frozen foods, crisp foods, etc. Composite of aluminum foil, plastic film, and kraft cardboard, it is non-toxic, odorless, pollution-free, and can be recycled and reused.
Aluminum-plastic composite film is widely used in food, chemicals, military supplies packaging and other fields. The milk and aseptic packaging mentioned earlier are made of aluminum foil and high-strength, heat-sealable plastic film. It has barrier, mechanical and heat sealing properties.
Aluminum-plastic composite hose is mainly used for packaging of paste-like and exposed products. It has the advantages of good insulation, not easy to break, clean and beautiful, etc. A set of data shows that more than 90% of toothpastes in developed countries such as Europe, the United States, and Japan are packaged in aluminum-plastic composite tubes. However, the rate of adoption of this packaging in my country is still very low, and there is still a lot of room for development.
Wine packaging. Many people know about wine, but many people don't know which part of the wine bottle is aluminum foil. Well, by the way, the aluminum foil on the wine bottle is the thin, wrinkled wine seal that wraps around the neck and mouth of the bottle. Because aluminum foil has good ductility, tensile properties and is easy to print, in recent years, with the requirements of beer hygiene standards, aluminum foil wine seals have gradually been widely used in bottleneck and bottle mouth sealing packaging of beer, fruit wine and high-grade soy sauce.
Medicine foil. This is very common. I'm sure you have had a cold. Even if you haven't had a cold, your family members have probably had a cold. Then you must have seen that board of hard plastic pills. If you want to take out the pills, you have to take them out. Tear off the foil. Well, having said that, don't blame me if you still don't understand. Generally speaking, pharmaceutical packaging aluminum foil mainly includes easy-open bottle caps for liquids and injections and medicinal PTP aluminum foil (sealing material sealed on plastic hard sheets). It is non-toxic, corrosion-resistant, impermeable, heat-resistant, moisture-proof, It has the advantages of light blocking and high temperature sterilization. Moreover, PTP aluminum foil is moisture-proof, easy to carry, safe and hygienic, and is widely used in the international pharmaceutical industry. In recent years, on the one hand, due to the rapid development of the pharmaceutical market, the application proportion of PTP aluminum foil in pharmaceutical packaging has been constantly mentioned, and the pharmaceutical foil market has also developed rapidly. It is expected that the compound growth rate of pharmaceutical foil will remain above 20%.
