Tetra Packaging
Aseptic brick is a packaging system that uses special cardboard for food as the base material, and is a paper package made of polyethylene, paper, aluminum foil, etc. It is a high-tech food preservation method, which means that the packaged liquid food is sterilized for a short time before packaging, and then under aseptic conditions, that is, the packaging, the packaged material, and the packaging aids are all sterile. Next, a packaging technology for filling and sealing in a sterile environment.

Capacity

Generally it is about 180-2000m1. There are two types of applications: refrigerated packaging and room temperature packaging. The common aseptic bricks on the market mainly have 4 kinds of raw materials: cardboard, polyethylene, aluminum foil and ink.

Cardboard

It does not directly touch 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 function is to strengthen the stiffness and hardness of the packaging after molding.

Polyethylene

Food grade polyethylene in aseptic packaging accounts for about 20% of the entire packaging, and its main function is to prevent liquid leakage and microbial invasion.

Aluminum foil

The weight of aluminum foil in aseptic packaging only accounts for about 5% of the entire package. The main function is to protect from light and block ventilation, keep the contents from being oxidized, reduce nutrient loss, and keep the taste fresh.

Ink

The weight of ink in aseptic packaging is minimal, but it is very important for hygiene and safety. The inks for packaging and printing of dairy and beverages on the market are mainly solvent inks and water-based inks.


Application field

Aseptic bricks are widely used in the processing of liquid dairy products, vegetable protein beverages, fruit juice beverages, alcohol products and drinking water. Aseptic packaging materials can include milk, juice and beverages, wine, water, tomato products, soups, etc. , Sweets, nutritious food and other products.


Development

Aseptic brick packaging materials not only have a good room for development in the dairy industry, but also have considerable development in other industries. The technical equipment of a large number of large-scale backbone enterprises in my country's beverage industry has approached or reached the international advanced level. In the future, the beverage industry will have a great demand for packaging equipment, especially filling equipment for non-gas beverages such as tea and juice. More than 90% of the domestic aseptic packaging material market is still occupied by Tetra Pak and Combibloc.

Summary

Aseptic brick packaging materials have a good development trend in my country due to their advantages. There are two main reasons for this. The first is that my country's milk production is mainly in the north, while the milk consumption in the south is larger than that in the north, and the room temperature packaging of milk is particularly urgent. Second, with the improvement of people's living standards, the demand for juice drinks and tea drinks has increased year by year. Therefore, the demand for aseptic packaged food is increasing. In the next few years, the output and quality of domestic aseptic composite packaging materials will be greatly improved. In the future, it is possible to enter famous domestic dairy groups such as Yili, Mengniu, and Guangming, thereby breaking the monopoly of multinational companies. The development prospects of aseptic packaging are very good, and the policy support of relevant national departments is urgently needed. Aseptic packaging products compete viciously in the low-end market and give up the domestic high-end aseptic packaging market to multinational companies.
