Characteristics And Applications Of PET Film

In addition to the excellent physical rigidity of ordinary polyester film, PET high-burning film also has excellent optical properties, such as good transparency, low haze and high radiance. It is used for high-pressure vacuum aluminum plating products. The film is mirror-coated with aluminum and has good packaging and decoration results. It can also be used for laser laser anti-counterfeit base film. The high-burning BOPET film has a large market capacity, high added value and obvious economic benefits.


PET transfer film is also called heat transfer film. This transfer film is characterized by high tensile strength, good thermal stability, low heat shrinkage rate, smooth and clean appearance, good peelability, and can be reused many times. It is used as a vacuum aluminum plating carrier. After the PET film is placed in a vacuum aluminum aluminizing machine, the rubber is coated with paper, and then the PET film is peeled off. The aluminum molecular layer is transferred to the appearance of the cardboard. Formed a so-called aluminized cardboard. The production process of the aluminized cardboard is: the PET base film release layer color layer aluminized layer coating layer is transferred to the cardboard. Vacuum aluminum-plated cardboard is a kind of advanced fresh packaging material that has been grown with metal-ray cardboard. This kind of aluminum-plated cardboard has a bright color and strong metallic sense. The KONE elevator accessories are bright and elegant, which can replace the large-area bronzing of printed matter, which has played a icing on the cake for the beautification of goods. Because it accepts the essentials of vacuum aluminum plating, the appearance of the cardboard is only surrounded by a thin layer of 0.25um~0.3um thin and precise aluminum, which is only one-fifth of the aluminum foil layer of aluminum foil, so that it It has a noble and elegant metal PET film, and it has degradable and environmentally friendly properties. It is a green packaging material.


The characteristic of PET reflective film is that the film has excellent optical properties, the appearance is smooth, smooth, good thermal stability, small shrinkage rate and light aging resistance. The reflective materials used in the traffic method include a lens-type retroreflective film and a quiet top-type reflective film. They are all made of an aluminized PET film as a reflective layer, and a glass with a refractive index of 1.9 after being coated with a pressure sensitive adhesive. The beads are adhered to the PET aluminized film, and then a layer of butadiene external protective layer is sprayed. PET reflective film is applied to billboards with reflective requirements, traffic reflective signs (reflective road signs, reflective cut-off belts, reflective number plates), reflective police uniforms, industrial tranquility signs, etc. Chemical coating film In order to improve the appearance of PET film, in order to improve the compliance of printing and the combined force of vacuum aluminum coating, the corona treatment penalty is usually accepted to improve the appearance 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, chemical coating rules do not have such problems, so they are favored by the printing industry and the aluminum plating industry.
