Aluminum occupies a high-end and key position in modern packaging industry through its unparalleled barrier, light and strong characteristics and high recyclability. From the beverage cans and snack bags we come into contact with every day, to the blister packaging to ensure the safety of drugs, and then to the kitchen aluminum foil to enhance the convenience of life, aluminum packaging has been deeply integrated into all aspects of daily life, and is an outstanding example of balancing product protection, easy use and environmental protection.
1. Excellent barrier provides comprehensive protection for food. It can completely block light, oxygen, moisture and microorganisms. This is very important to protect the flavor of the product, prevent oxidation deterioration and extend the shelf life. Aluminum food packaging can also preserve fragrance and taste, effectively prevent external odor from entering and internal aroma from escaping, and maintain the original flavor of the product.
2. Aluminum foil and aluminum material are easy to be stamped, stretched, bent and compounded, and containers of various shapes can be manufactured, such as cans, spray cans, toothpaste tubes and the like. At the same time, aluminum is easy to heat seal with plastics and other materials to form a firm seal and ensure the integrity of packaging.
3. Aluminum canned drinks can be cooled quickly. More importantly, cooking and packaging can make use of the thermal conductivity of aluminum foil, so that the food in the package can be heated evenly in the process of high-temperature sterilization, thus achieving aseptic fresh-keeping and long-term preservation.
4. The aluminum surface has natural metallic luster and good printability, which can print colorful, exquisite and gorgeous patterns and improve the product grade. It can be made into various colors and effects by anodizing and other processes to enhance the aesthetics.
5. Aluminum is a very recyclable material, and its recycling process only needs to consume 5% energy for producing primary aluminum. The high recovery rate of aluminum packaging makes it an important choice for environmental protection packaging, which is favored by brands and consumers with environmental awareness.
