Introduction to PVC film

- Jan 02, 2019-

PVC film, the full name is Polyvinylchlorid film. The main component is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness and ductility. The uppermost layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the lowermost layer is a back-coated adhesive.

It is a well-loved, popular and widely used synthetic material in the world today. The global use 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. Hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3. Soft PVC is generally used for the surface of floors, ceilings and leather, but 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 scope of use has been limited. Hard PVC does not contain softener, so it has good flexibility, easy to form, is not brittle, non-toxic and non-polluting, and has a long storage time, so it has great development and application value. Hereinafter referred to as PVC.

use

The essence of PVC is a vacuum plastic film, which is used for surface packaging of various types of panels. Therefore, it is also called decorative film and adhesive film, and is used in many industries such as building materials, packaging, medicine and so on. The building materials industry accounts for the largest proportion, at 60%, followed by the packaging industry, as well as several other small-scale applications.

Compared

The ordinary adhesive film is directly applied to the surface of the plate with glue at normal temperature, so after one or two years, the film is easily peeled off. The PVC film is applied to the surface of the sheet 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 comparable to natural materials, it can not eliminate 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 film in Germany are specially refined and the toxic substances are completely extracted. Therefore, PVC is completely non-toxic and tasteless, and has no stimulation to human skin or respiratory system. For those who are allergic to wood and paint, furniture or kitchen utensils wrapped in PVC film are very suitable. By using a PVC film as a decorative film, it is possible to use a medium-density board, a particle board, a plywood, and a fiber board in a large amount to reduce the amount of wood used.
