PROBLEM TO BE SOLVED: To provide a laminate tube container which can maintain an oxygen barrier property and appearance even when severe handling or severe retort processing is performed. SOLUTION: The laminate tube container is formed by using a laminate containing a gas barrier layer. The gas barrier layer is composed of a composition containing a hydrolysis condensate of a compound (L) and a neutralized product of a polymer (X) containing a carboxyl group. The compound (L) includes a compound (A) containing M<SP>1</SP>(Al or Ti or Zr) to which a characteristic group with hydrolyzing property is bonded and a compound (B) containing Si to which a characteristic group with hydrolyzing property is bonded. A part of -COO- group in the polymer (X) is neutralized by the metal ion of 2 or more valences. Eighty mol% or more of the compound (B) is a compound expressed by a predetermined formula. A ratio of [mole number of M<SP>1</SP>in the compound (A)]/[mole number of Si atom in the compound (B)] lies in a range between 0.1/99.9 and 35.0/65.0. COPYRIGHT: (C)2010,JPO&INPIT |
