Document Type and Number:
Japanese Patent JP5920521
Kind Code:
B2
Abstract:
In the multilayer bottle of the present invention, an outermost layer and an innermost layer are each composed of a polyester (Z1); a barrier layer is composed of a resin composition containing 40 to 99 parts by mass of a polyamide (X) and 1 to 60 parts by mass of a polyester (Z2); an alkali compound (A) is blended in the resin composition; and furthermore, the resin composition satisfies the following formulae (1) to (3). 0.01 ¤ P ¤ 6.5 3.2 ¤ M ¤ 73.1 M ¥ 29.2 - 0.218 ¢ ±
In the formulae, P represents a molar concentration (µmol/g) of phosphorus atoms; M represents a molar concentration (µmol/g) of alkali (earth) metal atoms; and ± represents the parts by mass of the polyamide (X) contained in the resin composition.
