Abstract

An injection blow molding method for making a container comprising the steps of injecting a molten crystallizable polymer in a preform mold via a hot runner system and biaxially stretching the preform by blowing, thereby forming a container, characterized in that said method further comprises means to selectively modify the flow path of the molten crystallizable polymer within the hot runner system.

Description

field of invention [0001] The present invention relates generally to new developments in thermoplastic preforms, in particular of the type used for blow molding containers, and more particularly relates to ) preforms. The invention also relates to a method for manufacturing said container, and in particular to a preform for the manufacture of said container, and to a method for manufacturing said preform. Background of the invention [0002] In beverage packaging, the use of plastic containers as an alternative to glass or metal containers has become increasingly popular. Several types of plastics have been used, ranging from aliphatic and aromatic polyolefins (polyethylene, polypropylene, polystyrene) to halogenated polymers (polyvinyl chloride, polyvinylidene chloride) and aliphatic polyamides (nylons) to aromatic polyesters. For the rigid food packaging segment, polyethylene terephthalate (PET), an aromatic polyester, is by far the most widely used resin. This choice ...
