Abstract

A process for producing a thermoplastic resin film through extrusion of a thermoplastic resin molten in an extruder (22) from a die (24) in the form of a sheet onto a rotating cooling roller (28) and cooling solidification thereof to thereby attain film forming. The process is characterized by including the extrusion step of extruding while controlling the extrusion temperature (T1) at the extrusion of molten thermoplastic resin through the extruder (22) so as to be in the range of T0-40°C to T0+30°C wherein T0 is the temperature at which when the thermoplastic resin is allowed to stand still in a nitrogen atmosphere for 1 hr, the thermal reduction thereof is 0.3 wt.% and the heating step of heating so that by landing of extruded thermoplastic resin on the cooling roller (28), the landing temperature is equal to or higher than the extrusion temperature.
