  • the film floats. , It occurs only in the number of pairs that is much closer to the bottom side than in the comparative example.
  • Example 4 in which the slit length is as long as 10 mm, a dip is observed in the last set of the 159th set, but it can be said that it is extremely unlikely to occur. In particular, despite the low pull-out resistance of the tissue paper, it is less likely to cause a drop.
