PROBLEM TO BE SOLVED: To provide a two-piece tube container in which the thermal welding property of the mouth with the cylindrical body and the gas barrier property are improved. SOLUTION: In a two-piece tube container in which the mouth head 2 is welded to the cylindrical body 1 made of a saponified substance of ethylene-vinyl acetate copolymer at the innermost layer, the mouth head 2 is constituted of a saponified substance (A) of ethylene-vinyl acetate copolymer, with 135 deg.C or higher in the melting point, polyolefin resin (B), and a saponified substance (C) of ethylene-vinyl acetate copolymer with 130 deg.C or lower in the melting point. The substance (A), (B) are composed of compounds existing as a matrix phase and a dispersed phase respectively. |
