Aluminum foil packaging bags have broad application prospects

Aluminum foil, commonly known as “tin foil”, is an aluminum rolled material extruded by a rolling press with aluminum ingots. The thickness is between 0.001mm and 0.2mm. Aluminum foil is hard, tin-flavo and will remain in food. In addition, the melting point of tinfoil is low, which is not suitable for grilling or baking food, which limits its application in food packaging. [Aluminum foil packaging bag] Aluminum foil is most commonly used in the field of food packaging. It is a soft metal film, which has the advantages of moisture resistance, corrosion resistance, airtightness, light shading, fragrance preservation, non-toxic and tasteless, and can keep food fresh for a long time. Extends the shelf life of butter by two to three months compa to tin foil. The thickness of aluminum foil in general food packaging bags is only 6.5μm (microns), and the thin aluminum layer has the functions of waterproofing, maintaining food freshness, preventing bacteria and preventing external pollution , so it is favo by food packagers. The production history of aluminum foil can be traced back to the beginning of the twentieth century. Before 1900, people could produce small batches of aluminum foil through the laborious and laborious hammering process. In the past 100 years, scientists have continuously improved production technology and equipment, making aluminum foil more and more Thin and thin, the output has also been greatly increased, which has broadened the application field of aluminum foil, from the early chocolate and butter packaging paper to the current development of beverage packaging, bottle caps, cigarette boxes, aluminum foil hydrogen balloons, etc. In addition to food, another application field that cannot be igno is pharmaceutical packaging, which is mainly reflected in blister packaging, which is currently the most important packaging method for Western medicine capsules. Blister packaging has the advantages of moisture-proof, easy to carry, safe and hygienic, and can effectively protect medicines that are sensitive to the environment. According to the Boston Consulting Group, the annual demand for aluminum foil in China’s packaging industry reached 350,000 tons in 2011, and the consumption is expected to exceed 900,000 tons in 2020. Among them, the demand for medical foil is the most obvious. As traditional Chinese medicine tablets, powders, capsules and pills move from paper bags and plastic bags to aluminum-plastic blister packaging, and China is gradually entering an aging society, the aluminum foil market for pharmaceutical packaging will be broader. food bags, food packaging bags
