<p><P>PROBLEM TO BE SOLVED: To provide a low cost multi-layer bottle which can hardly cause a peeling due to falling or impact, need not be of a shape having fewer uneven parts and bending parts for preventing the peeling, and has a high degree of design freedom and superior gas barrier properties. <P>SOLUTION: This multi-layer bottle has an outermost layer and an innermost layer formed of a thermoplastic polyester resin and at least, one barrier layer positioned between the outermost layer and the innermost layer. The barrier layer is a blend made up of at least, two components, i.e., a polyamide obtained by polycondensating a diamine component composed mainly of methaxylylenediamine and a dicarboxylic acid component composed mainly of anα,ω-straight-chain aliphatic dicarboxylic acid, and a polyamide with higher water absorption rate than the described polyamide. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
