<p>PURPOSE:To offer the titled thin bottle whose gas-permeability is inhibited, by biaxially elongating a laminate parison prepared by coating an unsaturated polyester resin parison with special nylon resin. CONSTITUTION:An adhesive agent 5, preferably unsaturated polyester resin, is applied to the outside surface of a preformed unsaturated polyester resin parison 1, and then the outside surface is coated with special nylon resin 6 prepared by polymerizing methaxylinylene diamine and adipic acid by an insert forming method to form a laminate parison 7. The laminate parison 7 is biaxially elongated into an objective bottle 8.</p> |
