Mengniu Pure Milk is mainly packaged in two forms, Tetra Pak and SIG. Among them, the Tetra Pak packaging is a unique composite material technology, which consists of paper, plastic and aluminum, forming the square brick design we commonly see. This type of packaging has a higher volume efficiency compared to plastic and glass bottles, facilitating stacking, transportation and storage in the logistics process, and is a common form of packaging for liquid products such as milk.

The composite material of the Tetra Pak package consists of three parts: firstly, the cardboard, which acts as the main support material and ensures the strength of the package while avoiding unnecessary weight gain. This cardboard comes mainly from wood, which, as a renewable resource, has a positive impact on the environment. Secondly, the polyethylene coating is a plastic used to seal the packaging to protect the milk from external moisture. Finally, the aluminum foil layer provides protection by preventing the milk from coming into contact with oxygen, preventing the odor from dissipating, and allowing the product to be stored for a long time without refrigeration.

Overall, Mengniu Pure Milk's Tetra Pak packaging design not only focuses on practicality, but also takes into account environmental protection and convenience, which is one of the key features of its products.
