[0002] Aluminum-plated pre-coated film is a composite material that is pre-coated with an extremely thin aluminum layer on the surface of a plastic film through a vacuum aluminum plating process to enhance its barrier properties, improve the decorative effect and give the material a metallic luster. When encapsulating electronic components, the aluminum-plated pre-coated film can be used as an inner layer material to play a role in moisture-proof and anti-static. The heat reflection properties of the aluminum-plated film can be used to make a heat dissipation pad or heat sink to help electronic equipment dissipate heat. In the case of electromagnetic interference shielding, the aluminum-plated pre-coated film can be used as a shielding layer to protect sensitive electronic components from interference.

[0003] The aluminum plating process of pre-coated film usually adopts the direct plating method, that is, the pre-coated film substrate is loaded into a vacuum evaporator, and the air is extracted by a vacuum pump to achieve a vacuum state. Then the crucible is heated to melt the high-purity aluminum wire at a high temperature of 1200℃~1400℃ and evaporate into gaseous aluminum; these gaseous aluminum particles are then deposited on the surface of the moving film substrate, and after cooling and reduction, a continuous and bright metal aluminum layer is formed.
