<p><P>PROBLEM TO BE SOLVED: To provide an oxygen absorptive multi-layer tube which has superior oxygen absorptiveness, gas barrier properties, and strength against inter-layer delamination to be able to well maintain the quality of contents for a long period. <P>SOLUTION: The oxygen absorptive multi-layer tube comprises a neck-to-mouth portion having a spout for the contents, and a trunk which is connected to the neck-to-mouth portion and has a fishtail-like tail end. At least the trunk is made of essential component layers composed of an inner resin layer, an oxygen absorptive gas barrier resin layer having effective components of a conjugate diene copolymer cyclized substance and an ethylene-vinyl alcohol copolymer, and a surface resin layer which are laminated from the inside toward the outside in an increasing order. Preferably, the neck-to-mouth portion is made of essential component layers composed of an inner resin layer, an oxygen absorptive gas barrier resin layer having effective components of a conjugate diene copolymer cyclized substance and an ethylene-vinyl alcohol copolymer, and a surface resin layer which are laminated from the inside toward the outside in the increasing order. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
