In life, we can often see the protective film, talking about the protective film in everyone's brain has been familiar, then these protective film in our usual use of the process, he is what kind of characteristics, according to the classification they can be divided into several types?
     PET protective film can be divided according to the use of die-cutting, electronic products, hardware products, automobiles and other products that need to be protected by the surface during the production process or storage process and transportation process, which can prevent the product from dust or other external pollution.

     From the material of the protective film, we can be divided into polyethylene, polyester, polypropylene and other materials, customers can customize the width, thickness and viscosity of the protective film according to the needs of their own products when purchasing the protective film, so as to reduce the manufacturing cost of the enterprise to a lower level, and the production efficiency of the enterprise to a higher purpose.
     According to the glue system, we can be divided into polyurethane, acrylic, organic silicone, acrylic. PET protective film is mostly based on organic silicone and acrylic glue.

     According to the market can be divided into the traditional protective film market, touch screen protective film market and high-end protective film market, the traditional protective film market most of the protective film used in the precision is not very high products, such as acrylic plate, peel or plastic, after continuous transformation and upgrading PET protective film gradually used in the mobile phone screen market. It has strict accuracy requirements regardless of thickness or viscosity, otherwise it will cause serious losses to the enterprise. The high-tech market has also begun to gradually use PET protective film for protection, which requires very high requirements and very high quality, such as the use of PET protective film on graphene heat sinks and nanomaterials, so enterprises must constantly improve their production quality while continuing to develop, in order to better fight with other enterprises.
