Abstract
PURPOSE: To obtain the multilayered container with high gas barrier property and high transparency by stretching a multilayered parison having an outer and an inner layers comprising a polyester resin and an intermediate layers comprising a polyamide resin containing a metaxylyrene group under a specified condition.
CONSTITUTION: A polyester resin having ethylene terephthalate as a main repeating unit is used as the outer and inner layers and a polyamide resin containing a metaxylyrene group is used as the intermediate layer to form the multilayered parison. Subsequently, the multilayered parison is heated to such a temp. that the surface temp. thereof is reached to a temp. up to Tg+15W2Tg+15 (Tg is a glass transition temp.) of a polyester resin and stretched to a longitudinal direction at a draw ratio of 1W4 times and to a lateral direction at a draw ratio of 2W7 times (a peripheral length stretch ratio of a lateral direction of a container).
