Small Pvd Coating Machine
It is suitable for manufacturing hot stamping film, laser film, gold and silver paperboard which need coating and laminating.
PET film is a relatively comprehensive packaging film. It has good transparency and luster; it has good air tightness and aroma retention; it has moderate moisture resistance, and its moisture permeability decreases at low temperatures. PET film has excellent mechanical properties, its toughness is the best among all thermoplastics, tensile strength and impact strength are much higher than general film; and it has good strength and dimensional stability, suitable for secondary processing such as printing and paper bags. . The PET film also has excellent heat resistance, cold resistance, and good chemical resistance and oil resistance. However, it is not resistant to strong alkali; it is easy to carry static electricity, and there is no proper antistatic method. Therefore, attention should be paid when packaging powdery articles.
(1) PET high gloss film
In addition to the excellent physical and mechanical properties of ordinary polyester films, the film also has excellent optical properties such as good transparency, low haze and high gloss. It is mainly used for high-grade vacuum aluminum plating products. The film is mirror-coated after aluminum plating, which has good packaging decoration effect; it can also be used for laser laser anti-counterfeit base film. The high-bright BOPET film has a large market capacity, high added value and obvious 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.
