(2) PET transfer film
The transfer film is also called a heat transfer film. The transfer film is characterized by high tensile strength, good thermal stability, low heat shrinkage, smooth surface and good peelability, and can be used repeatedly. It is mainly used as a vacuum aluminum plating carrier. After the PET film is placed in a vacuum aluminum plating machine, the rubber film is combined with the paper, and then the PET film is peeled off, and the aluminum molecular layer is transferred to the surface of the paperboard by the adhesive action. A so-called aluminized cardboard is formed. The production process of aluminized cardboard is:
PET base film→release layer→color layer→aluminized layer→glue layer→transfer to cardboard.
Vacuum aluminum-plated cardboard is a kind of high-grade novel packaging material developed with metal-gloss cardboard. This kind of aluminum-plated cardboard has bright color, strong metallic feeling, bright and elegant printing, and can replace the large-area bronzing of printed matter, which has played a icing on the cake for the beautification of goods. Because it adopts the vacuum aluminum plating method, the surface of the cardboard is covered with only a thin layer of 0.25um~0.3um thin and bright and bright, only one-fifth of the aluminum foil layer of the aluminum foil, so that it It has a noble and beautiful metallic texture, and has environmentally friendly properties that are degradable and recyclable. It is a green packaging material. Through the formulation and process adjustment, Jiangsu Zhongda was successfully developed in 2005 and put into the market in large quantities, receiving good economic benefits.

(3) PET reflective film
PET reflective film is characterized by excellent optical properties, smooth surface, smooth surface, good thermal stability, low shrinkage and light aging resistance.
Reflective materials used in transportation facilities include lens-type retroreflective film and flat-top reflective film. They are all made of aluminized PET film as a reflective layer. After applying pressure sensitive adhesive, some glasses with a refractive index of 1.9 are used. The beads are adhered to the PET aluminized film, and then a layer of butyral surface protective layer is sprayed.
PET reflective film is applied to billboards with reflective requirements, traffic reflective signs (reflective road signs, reflective barriers, reflective number plates), reflective police uniforms, industrial safety signs, etc.

(4) Chemical coating film
Polyester film In order to improve the surface properties of the PET film, in order to improve the adaptability of printing and the bonding force of the vacuum aluminum plating layer, a corona treatment method is generally used to increase the surface tension of the film. However, the corona method has problems such as aging, and particularly in a high-temperature, high-humidity environment, the film tension after corona treatment is easily attenuated. However, the chemical coating method does not have such a problem, so it is favored by the printing industry and the aluminum plating industry. Jiangsu Zhongda has developed a series of PET chemical coating products: coating with water-soluble polymer can improve the surface tension of PET film; coating with acrylate emulsion can improve printing adaptability (water-soluble ink can be used) The coating with polyurethane aqueous solution can strengthen the bonding force between the aluminum plating layer and the PET base film, and can increase the thickness of the aluminum plating layer.
In addition, a high-resistance film, an antistatic film, and the like can be obtained by a coating method.
