摘要： A process for producing amultilayeredunstretched film. The process is intended to minimize the amount of those thick parts of a film formed which are to be discarded, and to thereby attain a cost reduction. Thermoplastic resins (20A) and an extra thermoplastic resin (20B) different from the thermoplastic resins (20A) are separately melted by heating. Immediately before widening in respective manifolds, the extra thermoplastic resin is introduced to each edge part of each of the objective thermoplastic resins. The resins are fed to and widened in the manifolds so that the extra thermoplastic resin is disposed on the side of each edge of each objective thermoplastic resin. Subsequently, the melts are joined and ejected from the die lip of the T-die on a casting roll. Thus, a multilayered unstretched film is formed which comprises multilayered thermoplastic resins made of the objective thermoplastic resins and the multilayered extra thermoplastic resin disposed on the side of each edge of those multilayered resins. Thereafter, the parts constituted of the extra thermoplastic resin are removed by cutting to form a multilayered unstretched film (20) consisting mainly of the objective thermoplastic resins.
