PURPOSE:To obtain a molded article useful as a container for drugs, having surface gloss of stain like aluminum and improved chemical resistance, obtained by molding a composition consisting of a polyeste type resin and a polyolefin type resin by using a mold for injection molding having a satin processed inner face. CONSTITUTION:A composition consisting of 60-99.5wt% polyester type resin (>= 60mol% ethylene terephthalate) having an intrinsic viscosity of >=0.6 and 40- 0.5wt% at least one selected from a polyolefin type resin and a methacrylate type resin is injection molded by a mold for injection molding having a satin processed inner face, preferably by a screw having compression zone and a motering zone of three pitches respectively and by a mold having a compression ratio of 1.5-4, at a proper injection speed at a mold temperature <=50 deg.C. |
