摘要：
A method for manufacturing blown articles is disclosed wherein the article is manufactured from a parison having a high degree of multi-axial orientation. The method permits molecular orientation within the parison to be superposed with orientation imparted during the blowing step, whereby a blown article of greatly improved properties is manufactured.
