  • Injection stretch blow-molding process for the preparation of polymer containers
    Publication number: 20110221102
    Abstract: Injection stretch blow-molding process for preparing polymer containers, comprising the following steps: 1) covering, partially or totally, the outside surface of the core rod of a preform mold with a polymer film; 2) injecting a polymer layer over the covered core rod, thus obtaining a preform comprising an inside polymer film layer and an outside polymer layer; 3) stretch blow-molding the said perform, thus obtaining a container comprising an inside polymer film layer and an outside polymer layer.
