anti-static bag description anti-static bag is also called electromagnetic shielding bag. In order to shield the plastic from electromagnetic waves, it is necessary to metallize the plastic and use a material called an antistatic agent. Please note that the electromagnetic wave shielding here does not mean that the electromagnetic wave can be completely shielded like a metal sheet, but only to reduce the damage of the electromagnetic wave. Antistatic agents are divided into two categories: external coating type and internal addition type according to the method of use.
External antistatic agent is to disperse the antistatic agent in solvent, adhesive or hot melt adhesive powder, and make the antistatic agent adhere to the surface of the product by brushing, spraying or dipping on the outermost surface of the plastic to make the product. It has the effect of anti-static drag, and its advantages are that the operation is more convenient and the price is lower, but the durability is poor, and the surface is easily damaged and the anti-static function is lost. The internal addition type is to add antistatic agents to the formula before plastic molding. The product has antistatic effect and has a good lasting effect.
