what is Pvc film?
Feb 26, 2018

PVC film is made of PVC resin and other modifiers through calendering process or blow molding process. It is made up of PVC resin, plasticizer, stabilizer, filler and coloring agent.

The polyvinyl chloride film can be divided into two types, one is plasticized PVC film, the other is not plasticized PVC film, also called hard PVC film.Soft PVC is usually used for floor, ceiling and leather surface. However, soft PVC is easy to brittle because of its softening agent, so its application scope is limited. Hard PVC does not contain softener, so it has good flexibility, easy to form, not brittle, non-toxic and pollution-free, and has long preservation time. Therefore, it has great development and application value.

The PVC film production process is not complicated, the ordinary production line consists of roller press, printing machine, back coating machine and cutting machine, mainly through direct stirring roller, roller rotation and high temperature rolling production film thickness is only 0.3 mm to 0.7mm, and through the production of the printing machine at the color film printed on the front, through the back coating machine in the back of the membrane attached to a layer of back coating

PVC film is not soluble in water, alcohol and gasoline. It can swell or dissolve in ether, ketone, chlorinated aliphatic hydrocarbons and aromatics. At room temperature, it has strong hydrochloric acid, 90% sulfuric acid, 50%-60% nitric acid and less than 20% caustic soda solution.

The essence of PVC membrane is a vacuum plastic film, which is used for surface packaging of various panels. Therefore, it is also known as decorative film and adhesive film, which is applied to many industries, such as building materials, packaging, medicine and many other industries.
