Process for producing labeled hollow container

A process for producing a labeled hollow container, which comprises:

• inserting a label having a multi-layer structure into a hollow mold and blow molding a molten parison of a thermoplastic polypropylene or high-density polyethylene resin (designated thermoplastic resin C) in the mold, wherein said label is composed of a base layer comprising a thermoplastic polypropylene resin (designated thermoplastic resin A) having on one side thereof a heat-sealable resin layer comprising a mixture of at least two thermoplastic resins (designated lower-melting thermoplastic resin B and higher-melting- thermoplastic resin (B'), wherein said mixture is constituted from 10 to 55% by weight component (B') of a linear low-density polyethylene having a density of from 0.88 to 0.94 g/cm.sup.3 and a melt index of from 0.05 to 30 g/10 min and from 45 to 90% by weight of component (B) which is at least one resin selected from the group consisting of low-density polyethylene, an ethylene-methacrylic acid copolymer, an ethylene-acrylic acid copolymer, and an ethylene-vinylacetate copolymer, each of (B') and (B) having a melting point which is at least 20.degree. C. lower than that of said thermoplastic resin A, said mixture of thermoplastic resins B and B' satisfying the relationships:
• 5<T.sub.mC -T.sub.mB' <80
• 15<T.sub.mB' -T.sub.mB <50
• wherein T.sub.mC is the melting point of thermoplastic resin C constituting the parison;
• T.sub.mB' is the melting point of higher-melting thermoplastic resin B';
• and T.sub.mB is the 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 said heat-sealable resin layer.
