(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.

(5) PET antistatic film
The world today has entered the information age. Electromagnetic waves of various frequencies and wavelengths fill the entire earth space. These electromagnetic waves will cause different degrees of interference to unshielded sensitive electronic components, circuit boards, communication equipment, etc., resulting in data distortion. Communication is disordered. The static electricity generated by electromagnetic induction and friction on various sensitive components, instrumentation, certain chemical products, etc., such as high voltage discharge due to static accumulation of packaging film, the consequences will be destructive, so the development of antistatic PET packaging film is also very important. The antistatic film is characterized in that an antistatic agent is added to the PET film to form a very thin conductive layer on the surface of the film, and a continuous phase is formed to improve the surface electrical conductivity and cause the generated electric charge to leak as soon as possible. Generally, the surface specific resistance of the antistatic film is ≤109~11 ohms.

(6) PET heat sealing film
Ordinary PET is a crystalline polymer. When the PET film is stretched and oriented, it will produce a large degree of crystallization. If it is heat-sealed, shrinkage deformation will occur, so the ordinary PET film does not have heat-sealing properties. When PET film is used as a commodity packaging, in order to solve the problem of heat sealing, a method of compounding a BOPET film with a PE film or a CPP film is generally adopted, thereby limiting the application of the BOPET film to a certain extent.
In order to solve the heat sealing problem, a three-layer co-extruded heat-sealed PET film, a heat-sealed PET film, has been developed by modifying a PET resin and using an A/B/C three-layer die. Since one side is heat sealable, it can be directly heat sealed and is very convenient to use. The heat-sealed PET film can be widely used in various commercial packaging and card-protecting films
