PROBLEM TO BE SOLVED: To stably manufacture a film by executing a treatment for lowering a releasing strength on a part of a thin film-like formed product on a support where an end of the product is positioned in the case of releasing the product non-flowed after a flowable resin composition is formed on the support, thereby eliminating a rupture of the product. SOLUTION: The synthetic resin film is manufactured by continuously executing a flowable resin composition to become its raw material in a thin film state on a support such as a drum or the like, then drying, heating, cooling it to release a non-flowed thin filmy formed product from the support. In this case, a treatment for lowering a releasing strength is executed on a part of the support where an end of the product is positioned. That is, a roll 4 having an adhesive resin tape 2 having a predetermined width is installed is connected to a treating position of the drum or the like 6, the drum or the like 6 is rotated to feed a roll 4, and the tape 2 is stuck on an end of the drum or the like 6, thereby lowering a releasing strength of the non-flowed product. |
