ABSTRACT:
A method of manufacturing a multi-layer hollow article which consists of extruding a multi-layer parison having at least a chief resin layer, a sub resin (barrier) layer, and an adhesive resin layer located between the chief resin layer and the sub resin layer. The adhesive resin layer is made of the same essential material as the chief resin material and of the same quality. The sub resin layer is cut off by the use of a raised extrusion pressure of the adhesive resin when the multi-layer parison has been extruded a predetermined length. The parison is received in a mold so that the cut off sub resin (barrier) layer lies within the mold below pinch offs. Flash is produced as a result of the molding. The flash consists of the chief resin material or the chief resin material and the adhesive resin material. The flash is recycled as part of the chief resin material. Collecting a flash of a hollow article made by a blow molding and rebirthing the flash a rebirth chief resin material.
