シメチルセロースおよびその変性物を用いる。It is desirable that the back surface, which is the coated surface, be subjected to corona discharge treatment or anchor coat treatment for the purpose of improving the adhesion to the back treatment coating agent. Corona discharge treatment and anchor coat treatment are not required for the surface which is not coated. As the water-soluble polymer that is the binder of the back coating agent, polyvinyl alcohol and its modified product, carboxymethylserose and its modified product are used.

It is not limited to this range. Further, the mixing ratio of polyvinyl alcohol and carboxymethyl cellulose can be used in the range of polyvinyl alcohol: carboxymethyl cellulose = 10: 1 to 1: 9 in terms of solid content, but it is 6: 4 considering blocking property and repellency of the coated surface.
A degree is desirable. That is, polyvinyl alcohol alone has a problem of blocking property, and carboxymethyl cellulose alone has a problem of repellency of the coated surface.

形成する。In the present invention, a hydrophilic film is formed by forming a film on the back surface (corona discharge treated surface) of the polypropylene film with a water-soluble binder having good adhesion to the film. Therefore, even if a water-soluble starch, glue, or other bonding adhesive is applied after the film is formed, the coating surface does not flicker and uniform bonding is possible. Further, by adding hydrophilic cellulose powder to the water-soluble binder, the surface on which the film is formed becomes uneven, and the adhesive for laminating becomes easier to bite, so that it strongly adheres to the substrate for laminating. Cellulose powder also has the effect of preventing blocking by coating with a water-soluble binder. In addition, the surface on which the film is formed has a texture like paper, and a fir pattern feeling similar to that of the conventional product is formed.
