One of the key points of anti-static films is the prevention, because many electronics goods such as electronic components, computer cases, air conditioning display panels, computer fans, etc. need to be protected from static electricity and then prevent dust from going inside the goods or damaging the appearance hereof. At this time, the anti-static film is particularly required to have an anti-static function. Then what is the anti-static principle of anti-static film.
When the antistatic film is produced, an additive called anti-static agent is mainly added to the base material or glue, and it has the anti-static function. At present, most protective films on the market use pe or pet as the raw material. Before film blowing, a certain proportion of anti-static agent is added into the raw materials, and mixed evenly, plasticized by screw and blown into shape. Since the anti-static agent is uniformly dispersed in the film through water induction, and the anti-static agent is a low molecular weight surfactant, which has the characteristics of hydrophilic moisture absorption, and simply migrates from the film inside to the surface of the finished product to be hydrophilic, forming a water molecule layer, thereby achieving the function of discharging static electricity.
