|Thin film materials using laser holographic film is mainly PVC, PET, QPP, BOPP and other plastic film, a variety of laser holographic laser holographic film, transparent glazing film, laser holographic bronzing film, the color of gold, silver, red, blue, green, black, etc., are widely used in printing and packaging industry, as can be all kinds of adhesive paper, carton packaging, clothing label, laser holographic glass materials; adhesive can be used for interior decoration, advertisement decoration or lettering.
The laser holographic BOPP film can be widely applied to cigarette, wine, beverage and food packaging after compound treatment, giving the packaging anti-counterfeiting function and improving the packaging level.
The rheological property of PET is better in the melting state, and the effect of pressure on the viscosity is larger than that of the temperature. Therefore, the flow of the melt is changed mainly from the pressure. 1, the treatment of plastics is due to the PET macromolecule containing lipid base, which has a certain hydrophilicity. The pellets are sensitive to water at high temperature. When the moisture content exceeds the limit, the molecular weight of PET decreases, and the products are colored and crisp. Therefore, it is necessary to dry the material before processing, and the drying temperature is 150, 4 hours, generally 170, 3-4 hours. The air - ejection method is used to test whether the material is completely dry. Generally, the proportion of the recycled material should not exceed 25%, and the recycled material should be completely dried.
2, PET is chosen for injection molding machine. Because of its short time after melting point and high melting point, it is necessary to choose injection system with more temperature control section and less friction heat when plasticizing, and the actual weight of products (water cut material) should not be less than 2/3 of machine injection volume. Based on these requirements, in recent years, Ramada has developed a small and medium-sized series of PET special plasticizing systems. The clamping force is selected by more than 6300t/m2.
