In recent years, with the improvement of people’s living standards and the continuous entry of world-famous food companies into the Chinese market, China’s beverage industry has shown a vigorous development momentum. Among them, the consumption of high-quality and high-nutrition beverages is increasing day by day, almost every year. The speed increases above %. At the same time, beverage packaging has also become an important growth point in the packaging application field. So what kind of packaging should beverage packaging manufacturers choose?

At present, the common beverage packaging on the market is mainly divided into metal cans, composite plastic and paper packaging. There is no big difference between canned and aluminum foil PE flexible packaging for the quality and shelf life of the beverage. Filling it with inert gas such as nitrogen or carbon dioxide can extend the shelf life of the product.
 
1. Canned
The body of canned beverages is generally made of aluminum alloy sheet, which is canned by double crimping technology and nitrogen filling technology. Canned can become the most common form of high-end milk powder, mainly because of its excellent performance. Metal cans have strong barrier properties, can effectively block water, oil, light, etc., have good compression and tensile properties, are easy to transport and store, and can seal well and are not prone to insects. Moreover, metal packaging is easy to recycle, which can reduce environmental pollution. This is a way to respond to the call of the country under the general environment of the ban on plastics. However, the high cost of canned milk powder will increase the financial pressure of enterprises.

2. Composite plastic beverage packaging
The material of composite plastic beverage packaging is generally PET or biaxially oriented polypropylene film, which is manufactured by an extrusion process. The composite plastic packaging is light in weight, good in mechanical properties, stable in chemical properties, and the sealing performance meets the requirements, and it has suitable barrier properties and impermeability. However, during the sealing process of plastic composite film packaging, due to the characteristics of the beverage itself, or poor production technology, powder will be trapped at the horizontal seal.
 
3. Boxed
Boxed beverage packaging is mainly made of single-sided light food packaging paper, and boxed beverages are relatively rare at present. The box is an environmentally friendly material, degradable, recyclable, low in price, easy to process and print, but due to the nature of the carton itself, its barrier properties and water resistance are relatively poor, low wet strength, and short shelf life.
