PURPOSE:To eliminate a problem with respect to the formation of lines on a film in melt-extruding the compsn. into a film, by blending a polyester compd. with metallic titanium or a titanium alloy and a polysiloxane, a metal salt of a higher fatty acid or an alkyl sulfuric ester. CONSTITUTION:A polyester compd. is blended with 0.001-0.1wt% at least one member (A) selected from the group consisting of metallic titanium and titanium alloys and 5-500ppm of at least one member (B) selected from the group consisting of polysiloxanes, metal salts of higher fatty acids and alkylsulfuric esters. Examples of alloy elements for the titanium alloys are aluminum, molybdenum, chromium, iron, etc. and aluminum is particularly preferred. |
