Structure of PVC film
Sep 21, 2018

So what exactly is PVC? PVC, the full name is Polyvinylchlorid, the main ingredient is polyvinyl chloride, in addition to add other ingredients to enhance its heat resistance, toughness, ductility and so on. The top layer of this surface film is lacquer, the main ingredient in the middle is polyvinyl chloride, and the lower layer is the back-coated binder. It is one of the most popular and widely used synthetic materials in the world today. Its global use is the second highest in a variety of synthetic materials. According to statistics, only 1995 years, PVC production in Europe is about 5 million tons, and its consumption of 5.3 million tons. In Germany, the average production and consumption of PVC is 1.4 million tonnes. PVC is being produced and applied worldwide at a rate of 4%. The growth of PVC in Southeast Asia has been particularly significant, thanks to the urgent need for infrastructure in Southeast Asian countries.

In materials that can produce three-dimensional surface coatings, PVC is the most suitable material. PVC can be divided into soft PVC and hard PVC. Where hard PVC accounted for about 2/3 of the market, soft PVC accounted for 1/3. Soft PVC is generally used for floor, ceiling and leather surface, but because soft PVC contains softener (which is also the difference between soft PVC and hard PVC), easy to brittle, not easy to save, so its use range has been limited. Rigid PVC does not contain softener, so flexibility is good, easy to form, not brittle, non-toxic and non-polluting, long storage time, so it has great development and application value. Hereinafter are referred to as PVC. The essence of PVC is a vacuum blister film, used for all kinds of panel surface packaging, so also known as decorative film, with plastic film, used in building materials, packaging, medicine and many other industries.

The building materials industry accounted for the largest proportion of 60%, followed by the packaging industry, there are a number of other small-scale applications of the industry.
