Abstract

PURPOSE: To provide the titled container having excellent mechanical characteristics, heat resistance, appearance and moldability, by a method wherein a nonorientated and noncrystalline sheet (obtd. from a resin compsn. consisting of polyethylene terephthalate and polyarylate) is molded.
CONSTITUTION: 70W99wt% Polyethylene terephthalate having an intrinsic viscosity of 0.5 or above is mixed with 30W1wt% polyarylate having a reduced viscosity of 0.3W2.0 to obtain a resin compsn. which is then dried at 100W200°C for 20min or longer. Then the resin compsn. is supplied to an extruder provided with T-die, melt-extruded at 260W330°C, and quenched to obtain a nonorientated and noncrystalline polyester sheet having a thickness of 0.5W1mm. Then this sheet is softened by heating it at 120W180°C for 5W60sec., and then molded by a vacuum molding method or a pressure forming method.
EFFECT: There can be obtd. containers having excellent mechanical strength, shape retention properties and resistance to shrinkage by boiling water.
