What is the difference between PVC heat shrinkable film and ordinary adhesive film? Release time: 2017-06-14 　　 Ordinary adhesive film is directly attached to the surface of the board with glue at room temperature, so after one or two years, the film is easy to fall off. And the PVC film is a dedicated vacuum laminator It adheres to the surface of the board at a high temperature of 110 degrees, so it is not easy to fall off. 　　 Although PVC heat shrinkable film has excellent quality assurance, some people may say that PVC is a chemical product after all, it is not comparable to natural materials, and it cannot be ruled out Toxic and peculiar smells are also inevitably harmful to the environment. In fact, this is not the case. This is because the raw materials for the production of PVC films are specially refined, and toxic substances are completely extracted, so PVC is completely non-toxic and odorless, which is harmful to human skin. Or the respiratory system does not have any irritation. For those who are allergic to wood and paint, the use of PVC film packaging furniture or kitchen utensils is very suitable. By using PVC film as a decorative film, people can use a large number of medium dense boards , Particleboard, plywood and fiberboard, reduce the amount of wood used, thereby reducing the damage to the forest and the environment. From this perspective, PVC heat shrinkable film has made a great contribution to the protection of the ecological environment. 　　PVC heat shrinkable film is actually one A vinyl polymer material, the material is an amorphous material. In actual use, PVC materials often add stabilizers, lubricants, auxiliary processing agents, colorants, impact agents and other additives. It is non-flammable, High strength, weather resistance and excellent geometric stability. PVC has strong resistance to oxidants, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid and is not suitable Where it is in contact with aromatic hydrocarbons and chlorinated hydrocarbons. http://,PVC heat shrinkable film
