PROBLEM TO BE SOLVED: To provide a manufacturing method of a multi-layered film, wherein a film preferable for a packaging film or the like having excellent strength in a TD direction and adhesion properties, and at the same time utilizing excellent characteristics of a liquid crystal polymer, can be manufactured economically and industrially. SOLUTION: It is a manufacturing method of a multi-layered film containing a thermotropic liquid crystal polymer layer by using a co-extrusion machine. A thermoplastic polymer layer, which contains an epoxidized diene block copolymer having adhesion properties at least to the liquid crystal polymer layer, is formed and, in this state it is extruded in multi layers for manufacturing a multi-layered film. |
