くという問題があった。A conventional adhesive label is:
Since a non-disintegrable material such as a transparent synthetic resin film such as polyethylene terephthalate or polypropylene is used as a sheet for lamination, it is difficult to reuse the material, and most of the materials have been incinerated. In addition, when this is to be disintegrated and regenerated, it is necessary to separate the non-disintegrable portion from the adherend such as a paper material. Furthermore, if the non-disintegrable portion is mixed into an adherend such as a paper material, there is a problem in that the recycling operation is hindered and the price of the recycled product increases.
