Abstract:
The present disclosure provides a film for application to the living body, which is advantageous for bonding to the living body, while containing a regenerated cellulose. A film (10a) for application to the living body according to the present disclosure is a self-supporting film which contains a regenerated cellulose, while having a thickness of from 20 nm to 2,000 nm. This film (10a) for application to the living body has a first main surface (11) and a second main surface (12) which is on the reverse side of the first main surface 11. This film (10a) for application to the living body has a planer first region (13) and a planer second region (14). The first region (13) is in contact with the first main surface (11) in the thickness direction of the film (10a) for application to the living body, while being positioned at a distance from the second main surface (12). The second region (14) is positioned between the first region (13) and the second main surface (12) in the thickness direction of the film (10a) for application to the living body. The bulk density of the regenerated cellulose in the second region (14) is higher than the bulk density of the regenerated cellulose in the first region (13).
