This film not only has the excellent physical and mechanical properties of ordinary polyester film, but also has excellent optical properties, such as good transparency, low haze, and high glossiness. It is mainly used for high-end vacuum aluminized products, and the film has a mirror like surface after aluminizing, which has a good packaging and decoration effect; It can also be used for laser anti-counterfeiting base films, etc.
Transfer film, also known as heat transfer film, is characterized by high tensile strength, good thermal stability, low thermal shrinkage rate, smooth and smooth surface, good peel resistance, and can be repeatedly used. It is mainly used as a carrier for vacuum aluminum plating, which is to place the PET film on the vacuum aluminum plating machine for aluminum plating, glue it onto the paper, and then peel off the PET film. The aluminum molecular layer is transferred to the surface of the cardboard through adhesive action, forming the so-called aluminum plated cardboard. The production process of aluminum coated cardboard is as follows:

Vacuum aluminized cardboard is a type of metal glossy cardboard that has been developed in recent years as a high-end and novel packaging material. This type of aluminum plated cardboard has a bright color, strong metallic feel, and a bright and elegant printed product. It can replace the large-scale gilding of printed products, playing a icing on the cake role in beautifying the product. Due to its use of vacuum aluminum plating method, it only covers a thin and tightly bright aluminum layer of 0.25-0.3um on the surface of the cardboard, which is only one fifth of the aluminum foil layer of the laminated aluminum cardboard. This not only gives it a noble and beautiful metal texture, but also has biodegradable and recyclable environmental properties, making it a green packaging material. Jiangsu Zhongda successfully developed and put it on the market in large quantities in 2005 through formula and process adjustments, receiving good economic benefits.
