Dairy products

dairy products: refers to the use of milk or goat milk and its processed products as the main raw material, with or without the addition of appropriate amounts of vitamins, minerals and other auxiliary materials, the use of laws, regulations and standards required by the conditions, processed into a variety of food, also called cream products.

In recent years, with the sustained and stable economic development and the improvement of living standards, China's dairy industry has entered a period of rapid development and has rapidly grown into one of the industries with better prospects in food. As a member of dairy products, milk powder has been increasing at a rate of more than 25% every year in recent years. In line with this, milk powder packaging has also become an important growth point in the field of packaging applications.

At present, there are mainly two forms of metal cans and plastic flexible bags. Metal cans have good sealing performance and long shelf life, but their production and transportation costs are relatively high. The market price of canned milk powder of the same quality is generally more than 30% higher than that of bagged milk powder. With the intensification of competition, metal can packaging has the possibility of being gradually replaced by lightweight plastic packaging.

As one of the main ways of milk powder packaging, plastic flexible packaging bags mainly have the following four structures.

Structure 1:/PET AL/NY/PE; AI 2: AL/PE; AI 3:PET/VMPET/PE; AI 4:BOPP/VMPET/PE
