We can find that PET protective film can often be seen in daily life, whether it is from mobile phones or tablets or other electronic products and other products, we can see the existence of protective film, why PET protective film can be used in such a wide range? Therefore, this paper analyzes the relevant characteristics of PET protective film:

       PET antistatic screen protective film: now has entered the information age, electronic products have begun to increase, automation equipment also has more stringent precision requirements, the use of PET antistatic screen protective film has become more and more, many electronic products in the production process need to receive good quality protection. In the production process, the static electricity generated by electromagnetic induction and friction will cause damage to electronic products. In order to reduce the damage of products in the production, most products need to use PET mesh protective film. It can form a relatively thin conductive layer on the surface of the protective film, improve the surface conductive property, and guide the static electricity through the conductive layer. Allow the resulting load to leak quickly.

      PET shrinkable film: PET shrinkable film is a new type of packaging material, because the PET substrate is non-toxic, odorless, convenient recycling and other advantages, the use of PET shrinkable film can achieve the role of protecting the environment, in many developed countries PET shrinkable film has replaced PVC shrinkable film.
