Abstract
Improve the strength of the stretch blow receptacle and make the heat resistant treatment easier, by making the receptacle wall cross-section multi-layered in view of crystalline density, and the crystalline density of the surface layer high density. The inventions concerns a thin plastic receptaclemolded by stretch blowing of a bottomed preformin the longitudinal and transversal directions. The wall cross-section is composed of inside and outside surface layerswhose crystalline density is high by stretching, a core layerpresenting a lower density than the surface layers, and an intermediate layerpresenting a graduated density between both layers
