Why is there too much static on the surface of the PET film? -Film supplier

One characteristic of electrostatic phenomenon is adsorption. When the surface of the PET film is rubbed, or the film roll is peeled off, or the film is running at high speed, static electricity will be generated. If there is dust, paper scraps, hair, etc. near the film at this time, it may be adsorbed, which affects the quality of the product film (especially the capacitor film). When the static electricity is serious, it may also cause fires, electricians and other accidents. Known polyester The static electricity of the film is too large, which will have a bad effect on the subsequent processing and processed products. For example, the static electricity of the bonded PET film can be set at about 500v with an electrostatic tester. The measurement shows that the static electricity of the two sides of the film is also different. Reasons Analysis PET film is a polar electrical insulating material, which makes the charge generated by friction, shearing, etc. unable to pass away, and accumulates on its surface to form static electricity. The size of the static electricity of the PET film and the electrical properties of the resin body. The application of additives It is related to the film making process. Because they directly affect the structure and performance of the film surface/surface, such as the crystallinity of the surface layer, the number of polar groups and their orientation, the size of the contact area between the two films, and other factors that affect the formation of static electricity. Based on this, it can also explain why the static electricity on both sides of the film is different. Solution a. Find out the reason from the resin, additives, and process and solve it in a targeted manner; b. Use static eliminator C in the film production and post-processing of the film. , Coating a conductive layer d on the surface, using antistatic agent/resin.
