So what exactly is PVC? PVC (Polyvinylchlorid in full name) is made of polyvinyl chloride (PVC) with other ingredients added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is lacquer, the main component in the middle is PVC, and the bottom layer is backed with adhesive. It is a kind of synthetic material which is popular and widely used in today's world. It is the second most widely used synthetic material in the world. 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 averaged 1.4 million tons. PVC is being produced and applied worldwide at a rate of 4%. PVC growth has been particularly significant in Southeast Asia, where there is an urgent need to build infrastructure. PVC is the most suitable material for producing 3d surface film.

PVC can be divided into soft PVC and hard PVC. Hard PVC accounted for about 2/3 of the market, and soft PVC accounted for 1/3. Soft PVC is generally used for floor, ceiling and leather surface, but because soft PVC contains softener (this is also the difference between soft PVC and hard PVC), easy to become brittle, not easy to save, so its use scope is limited. Hard PVC does not contain softener, so good flexibility, easy molding, not easy to brittle, non-toxic, pollution-free, long preservation time, so it has great development and application value. Hereinafter referred to as PVC. The nature of PVC is a vacuum blister film, used for the surface packaging of all kinds of panels, so it is also known as decorative film, adhesive 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, and a number of other small applications of the industry.
