- white powder was generated more frequently because the amount of the slip agent added was too large.
- Comparative Example 2 since the amount of the slip agent was smaller than that in Comparative Example 1, the generation of white powder was suppressed. However, since the surfaces of the male member 21 and the female member 22 are tacky, the running performance of the separator 3 12 is poor, the separation speed of the separator 3 12 is slow, and the bag making efficiency is low. Has gone down.
