The bacterial packaging material is a packaging system that uses a special paperboard as a base material, and is a paper package composed of polyethylene, paper, aluminum foil, and the like. It is a high-tech food preservation method. It means that the packaged liquid food is sterilized for a short period of time before being packaged, and then under aseptic conditions, that is, when the packaged goods, packaged goods, and packaging aids are all sterile. Next, fill and seal a packaging technology in a sterile environment.
The capacity is generally around 180-2000m1. There are two types of applications: refrigerated packaging and ambient temperature packaging. The refrigerated packaging includes milk roof packs, bricks, pillows and juice roof packs. Normal temperature packaging includes sterile bricks, sterile pillows, and hot-filled roof packs. The paper-aluminum composite aseptic packaging materials commonly found on the market today consist of four types of raw materials: cardboard, polyethylene, aluminum foil and ink. Cardboard does not directly contact the contents of the package, but it is an important part of the package, accounting for about 75% of the entire package weight. The main role is to strengthen the stiffness and hardness of the package after molding. Polyethylene, aseptically packaged in polyethylene, weighs approximately 20% of the entire package. Its main function is to block liquid leakage and microbial attack. The weight of aluminum foil in the aseptic packaging of aluminum foil only accounts for about 5% of the entire package. The main role is to protect the light and block the ventilation, to keep the contents from being oxidized, reduce nutrient losses, and keep the taste fresh. Ink inks have a negligible weight in aseptic packaging but are very important for hygiene and safety. At present, the printing and printing inks for dairy products and beverages on the market are mainly solvent inks and water-based inks.
Sterile paper packaging materials are widely used in the processing of liquid dairy products, vegetable protein beverages, fruit juice beverages, alcohol products, and drinking water. Sterile packaging materials can include milk, juices and beverages, alcohol, water, and tomato products. Soups, sweets, nutritious foods and other products.
Aseptic packaging technology not only has a good development space in the dairy industry, but also has made great progress in other industries. The technical equipment of a large number of large-scale backbone enterprises in the beverage industry in China has approached or reached the international advanced level. In the future, the beverage industry will have a great demand for packaging equipment, especially tea fillings and juice-free beverage filling equipment. Now more than 90% of the aseptic packaging material market in China is still occupied by Tetra Pak and Combibloc.
Aseptic packaging materials are bright and fresh due to their advantages, and have a good development trend in China. There are also two main reasons for this. The first one is that China’s milk production is mainly in the north, and the consumption of milk in the south is larger than that in the north. The normal temperature packaging of milk is particularly urgent. Second, as the standard of living of the people improves, the demand for fruit juice drinks and tea drinks increases year by year. As a result, the demand for aseptically packaged foods continues to increase. In addition to multinational companies in the processing of aseptic composite materials, the output and quality of domestic aseptic composite packaging materials will greatly increase in the coming years. In the future, it is possible to enter domestic famous dairy groups such as Yili, Mengniu and Guangming, thereby breaking the country’s The monopoly of the enterprise. The development prospect of aseptic packaging is very good. At present, it urgently needs the support of the relevant national departments and policies. Sterile packaging products compete in the low-end market and give away the domestic high-end aseptic packaging market to multinational companies.
