The aluminum-plated composite product has the characteristics of a plastic film and is also brighter in appearance, thus beautifying the packaging of the product; in addition, it replaces the aluminum foil composite packaging.

The use of aluminized film in packaging has the following advantages:

 (1) Aluminized film has good metallic luster and good reflectivity. Using it to package goods can play a role in beautifying goods and increasing the grade of goods.

 (2) Aluminized film can replace aluminum foil, but the amount of aluminum used is greatly reduced, which not only saves energy and materials, but also reduces the cost of product packaging relatively speaking.

(3) The aluminized layer on the surface of the aluminized film has good electrical conductivity, so it has good sealing performance. When packing powdery items, the package can be sealed, thereby greatly reducing the incidence of leakage.

It is precisely because of the advantages of the above aspects that the application of aluminized film has become more and more extensive, and it has become a popular packaging material in the flexible packaging industry. There are many types of aluminized films. At present, the most widely used aluminized films are mainly polyester aluminized film (VMPET) and CPP aluminized film (VMCPP). Polyester aluminized film (VMPET) is generally used as the middle layer of composite packaging. , Because of its beautiful appearance, it is widely used in packaging, such as milk powder, tea and other packaging bags. CPP aluminized film (VMCPP) is generally used as a heat-sealing layer for composite packaging, and is often used for packaging of ordinary small foods (such as biscuits).
