Further, even when a specific linear low density polyethylene is added to polypropylene as described in Patent Document 3, further improvement in transparency is desired. Furthermore, in the configuration of Patent Document 3, since materials other than polypropylene must be added, the configuration is not a monomaterial, and it is difficult to recycle. Therefore, how to reduce the production of spherulites is a key point for further transparency. And by the present inventors' earnest study, it has been found that by controlling the stress applied during the extrusion of the resin, the crystal formed by the subsequent rapid cooling is changed.
