ことである。When the material is treated with the latter method of surface coating, a better antistatic effect is observed. In many cases,
The antistatic agents used are water-soluble, low-lying-r11 or polymeric products. As a result, this coating exhibits a high antistatic effect when it absorbs moisture, and the static friction coefficient between the surface coating layers decreases due to the water coating. This may cause damage. Therefore, an object of the present invention is to provide a thermoplastic film 1) which has a high antistatic effect and at the same time has a coefficient of static friction that prevents the bag from shifting or collapsing.
