초록

A multi-layer preform for forming multi-layer containers includes an extruded upper portion having a first thickness which is adapted to form an upper portion of a container. The preform also includes an extruded intermediate portion having a second thickness thicker than the first thickness. The intermediate portion is connected with the upper portion and is adapted to form an intermediate body portion of the container. The preform also includes an extruded base portion having a third thickness thicker than the second thickness. The base portion is conn...
