PVC film, full name is Polyvinylchlorid film. The main ingredient is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness and ductility. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is a back coating adhesive.
It is a synthetic material that is loved, popular and widely used in the world today. The global usage of PVC film ranks second among various synthetic materials. Among the materials that can produce three-dimensional surface films, PVC is the most suitable material.
classification:
PVC film can be divided into PVC soft film and PVC hard film. Among them, hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3. Soft PVC is generally used for flooring, ceiling, leather surface and various types of adhesive tapes. However, because soft PVC contains softener (this is also the difference between soft PVC and hard PVC), it is easy to become brittle and difficult to store, so its use range Limitations. Hard PVC does not contain softener, so it has good flexibility, easy to form, not easy to brittle, non-toxic and non-polluting, and long storage time, so it has great development and application value.
use:
The essence of PVC is a vacuum blister film, which is used for the surface packaging of various panels and the base layer of various adhesive tapes. Therefore, it is also known as decorative film and adhesive film. Among them, the building materials industry accounts for the largest proportion, 60%, followed by the packaging industry, as well as several other small-scale applications.
Differences between PVC film and ordinary adhesive film:
The ordinary adhesive film is directly pasted on the surface of the board with glue at normal temperature, so after one or two years, the adhesive film will easily fall off. The PVC film is pressed on the surface of the board at a high temperature of 110 degrees by a dedicated vacuum laminator, so it is not easy to fall off. Although PVC film has excellent quality assurance, some people may say that PVC is a chemical product after all. It is not as good as natural materials, it cannot exclude toxicity and odor, and it will inevitably cause harm to the environment. This is not the case. This is because the raw materials for the production of PVC films in Germany are specially refined and toxic substances are completely refined. Therefore, PVC is completely non-toxic and tasteless, and has no irritation to human skin or respiratory system. For people who are allergic to wood and paint, furniture or kitchenware that uses PVC film packaging is very suitable. By using PVC film as a decorative film, people can use a large number of medium-density board, particleboard, plywood and fiberboard, reducing the amount of wood used.
