Abstract
An injection blow molding method for making a container having the steps of injecting a molten crystallizable polymer in a preform mold via a hot runner system and biaxially stretching the preform by blowing to form a container. The method further having the step to selectively modify the flow path of the molten crystallizable polymer within the hot runner system.
Claims23
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 to form a container, wherein the preform comprises regular or irregular sequence of variations in molecular pre-alignment/orientation between different locations of the cross-section of the preform.
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 to form a container, wherein the preform comprises regular or irregular sequence of variations in molecular pre-alignment/orientation and regular or irregular sequence of variations in crystallinity between different locations of the cross-section of the preform.
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 to form a container, comprising selectively modifying the flow path of the molten crystallizable polymer within the hot runner system.
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 to form a container, wherein the container comprises regular or irregular sequence of variations in molecular pre-alignment/orientation and regular or irregular sequence of variations in crystallinity between different locations of the cross-section of the container.
The preform suitable for blow molding made out of crystallizable polymers, wherein the preform comprises regular or irregular sequence of variations in molecular pre-alignment/orientation.
The preform suitable for blow molding made out of crystallizable polymers, wherein the perform comprises regular or irregular sequence of variations in molecular pre-alignment/orientation and regular or irregular sequence of variations in crystallinity between different locations of the cross-section of the preform.
A container made by blow molding out of crystallizable polymers comprising a regular or irregular sequence of variations in molecular pre-alignment/orientation and regular or irregular sequence of variations in crystallinity between different locations of the cross-section of the container.
