PVC film, the main component is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive.

It is a synthetic material that is 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 floors, ceilings and leather surfaces, but because soft PVC contains softeners (this is also the difference between soft PVC and hard PVC), it is easy to become brittle and difficult to preserve, so its scope of use is limited. Hard PVC does not contain softeners, so it has good flexibility, is easy to form, is not brittle, is non-toxic and pollution-free, and has a long shelf life, so it has great development and application value. hereinafter referred to as PVC.

Purpose

PVC is essentially a vacuum blister film, which is used for the surface packaging of various panels, so it is also called decorative film, adhesive film, and is used in many industries such as building materials, packaging, and medicine. Among them, the building materials industry accounts for the largest proportion, which is 60%, followed by the packaging industry, and there are several other industries with small-scale applications.

Comparison

The difference between PVC film and ordinary adhesive film

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. PVC film is attached to the surface of the board at a high temperature of 110 degrees using a special vacuum laminating machine, 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 eliminate toxicity and odor, and it is inevitable to cause harm to the environment. This is not the case. This is because the raw materials used to produce PVC film in Germany are specially refined, and the toxic substances are completely extracted. Therefore, PVC is completely non-toxic and tasteless, and has no irritation to human skin or respiratory system. For those who are allergic to wood and paint, furniture or kitchenware packaged in PVC film is very suitable. By using PVC film as a decorative film, people can use medium-density boards, particle boards, plywood and fiberboards in large quantities, reducing the amount of wood used.
