PROCESS FOR PRODUCING LABELED HOLLOW CONTAINER

摘要

A process for producing a labeled hollow container comprising inserting a label having a multi-layer structure into a hollow mold and blow molding a molten parison of thermoplastic resin C in the mold is disclosed, in which the label is composed of a base layer comprising thermoplastic resin A having on one side thereof a heat-sealable resin layer comprising a mixture of at least lower-melting thermoplastic resin B and higher-melting thermoplastic resin B' both having a melting point at least 20 DEG C lower than that of the thermoplastic resin A, the mixture of thermoplastic resins B and B' satisfying relationships: 5 < TmC - TmB' < 80 15 < TmB' - TmB < 50 wherein TmC is a melting point of thermoplastic resin C constituting the parison; TmB' is a melting point of higher-melting thermoplastic resin B'; and TmB is a melting point of lower-melting thermoplastic resin B, and lower-melting thermoplastic resin B being present in a proportion of from 10 to 60% by weight based on the heat-sealable resin layer. The in-mold label suffers from no blister even when the molding cycle is shortened.
