PVC Heat Shrink Film Material Characteristics

PVC heat shrink film material has non-flammability, high strength, weather resistance and excellent geometric stability.PVC has strong resistance to oxidizing agents, 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 for contact with aromatic and chlorinated hydrocarbons. Ordinary adhesive film is directly pasted on the surface of the sheet with glue at room temperature, so after one or two years, the film is easy to fall off. On the other hand, PVC shrink film is attached to the surface of the sheet by applying a special vacuum film press at a high temperature of 110 degrees, so it is not easy to fall off.

Although PVC heat shrink film has excellent quality assurance, but some people may say, PVC is ultimately a chemical product, it is no better than the material, excluding toxicity and odor, but also inevitably harm the environment. This is not the case, this is because the general production of PVC shrink film raw materials are specially refined, toxic substances are refined, so PVC is odorless, no stimulation of the human skin or respiratory system, for those who are allergic to wood and paint, the use of PVC heat shrink film packaging of furniture or kitchen utensils is very suitable.

By using PVC shrink film as decorative film, people can use a large number of medium density board, particle board, plywood and fiberboard, reducing the amount of wood used, thus reducing the damage to the forest and even the environment. From this point of view, PVC heat shrink film makes a great contribution to the protection of the ecological environment.
