Since it is slippery, it is difficult to pick up, and further, the release paper tends to be cut off at the time of production, which tends to reduce workability. On the other hand, if the thickness of the release paper exceeds 150 m, it will be difficult to cut the release paper, and it will be difficult to cut the raw sheet at the time of manufacturing, and the working efficiency will tend to decrease.

That is, since the sheet pack has a relatively complicated shape, it is difficult to peel off the release paper and stick it to the skin such as the face if the cut portion does not exist as described above. There was also a problem in terms of hygiene, as it was easy for seizures to occur and it was necessary to directly touch the pack agent layer.

This makes it possible to achieve both of the generally contradictory characteristics of the difficulty of peeling off at the time and the improvement of the performance of removing aged skin cells.
