What is the use of PVC film in work and life?

The top layer of the surface film of PVC is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is the back coating adhesive. It is a well-loved, popular and widely used synthetic material in the world today. Its global usage is the second highest among all synthetic materials. According to statistics, in 1995 alone, the production of PVC in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, PVC production and consumption average 1.4 million tons. PVC is being produced and applied worldwide at a growth rate of 4%. In recent years, the growth of PVC in Southeast Asia has been particularly significant, thanks to the urgent need for infrastructure construction in Southeast Asian countries. Among the materials that can produce three-dimensional surface films, PVC is the most suitable material. PVC is a polyvinyl chloride plastic with bright color, corrosion resistance, firmness and durability. Due to the addition of some toxic auxiliary materials such as plasticizers and anti-aging agents in the manufacturing process, its products generally do not store food and medicine. PVC can be divided into soft PVC and hard PVC. 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 the surface of floors, ceilings and leather, 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 store, so its scope of use is limited. Hard PVC does not contain softeners, so it has good flexibility, easy to form, not easy to be brittle, non-toxic and pollution-free, and has a long storage time, so it has great development and application value. Hereinafter referred to as PVC. The essence of PVC is a vacuum blister film, which is used for the surface packaging of various panels, so it is also called decorative film and 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, accounting for 60%, followed by the packaging industry, and several other small-scale application industries.
