An outstanding focus of anti-static protective film is on anti-static, because many electronic products, such as electronic components, computer chassis, air conditioner display panel, computer fan, etc., need to prevent static electricity, and then cause dust to enter the interior of the product or damage the appearance of the product. At this time, the anti-static protective film needs to have an anti-static function, so what is the anti-static principle of the anti-static protective film.

When the anti-static film is produced, an antistatic additive called antistatic agent is added to the base material or glue, and then it has the anti-static function. At present, most of the protective films on the market use PE or pet as the raw materials. Before the film blowing, a certain amount of antistatic agent is added to the raw materials, and then it is mixed evenly and molded by screw plasticizing film blowing, because the antistatic agent is uniformly distributed in the film through the induction of water, In addition, the antistatic agent is an external active agent with low molecular weight, which is hydrophilic and hygroscopic. It simply migrates from the inside of the membrane to the surface of the finished product, forming a water molecular layer, so it can discharge static electricity.
