PURPOSE:To make a slide sheet transparent and to keep the low frictional property and the antistatic property for a long period by providing an antistatic layer on a porous film made of a super molecular weight polyethylene and allowing an antistatic material to penetrate minute holes and applying a pressure on a specific temperature condition. CONSTITUTION:The antistatic layer is provided on at least one face of the super molecular weight polyethylene porous film having minute holes and is penetrated with the antistatic material. The porous film is pressurized at a temperature higher than the melting point of the super molecular weight polyethylene to minimize diameters of minute holes, thereby making the film transparent. Since the antistatic material exists not only on the surface but also in the porous film and a pressure is applied on a specific temperature condition in this manner, a transparent slide sheet which keeps the low frictional property and the antistatic property for a long period is obtained. |
