Bopp aluminum coating is a high-temperature treatment process that melts aluminum into a gas state.
1. Production mode
Bopp aluminum coating is a high-temperature treatment process that melts aluminum into a gas state. After passing through the vacuum evaporation chamber where the plastic film is located, aluminum molecules naturally settle on the plastic film, producing a metallic aluminum luster. Strictly speaking, its main material is still plastic, which has the toughness of plastic and the characteristics of metal. It is a highly practical packaging product.
Aluminum foil is a hot stamping material made by directly rolling aluminum into thin sheets. Due to the soft texture of aluminum itself, it is pressed into thin plates during processing, coated with sodium silicate, and printed. It can also be used as a packaging material.
2. The cost of production
In aluminum plated film, plastic is mainly used, which has a fast production speed and high output, while aluminum foil requires a large amount of aluminum. Due to the high price of aluminum material, the production cost of aluminum plated film is lower, so its popularity is higher.
3. Durability
Due to the high content of aluminum element in aluminum foil, it is easy to oxidize in the air, resulting in darkening of color and decreased glossiness. The surface aluminum of bopp aluminum plating film is treated at high temperature, making it less prone to oxidation and corrosion. In terms of durability, it has more advantages.
