Abstract

PURPOSE:To prevent the obtained primary molding from chalking by a method wherein when a barrier layer body is extruded in a manner that the external superficial face of the inner layer body molded with polyethylene terephthalate is covered, a protective material is installed at a gate part of the inner layer body. CONSTITUTION:When the primary molding of a polyethylene terephthalate (hereafter referred to as PET) resin laminated molding is molded, an inner layer body 2 of a drum type having a bottom is extruded with PET, and a barrier layer body 5 by means of a synthetic resin material such as a polyamide resin, etc. having a high gas barrier quality is extruded in a manner that the inner layer body 2 is made a part of a mold and the external superficial face of the inner layer body 2 is covered. At this time, a protective material 4 having a heat resistance, heat insulating quality and a righdity such as an Al foil is positioned and attached to the gate 3 part of the inner layer body 2 in order that the extrusion pressure and heat of a mold resin material of the barrier layer body may not give a direct operation, and with this, the primary molding can be prevented from chalking.
