Abstract

A device for producing pre-stretch film includes a die defining a die outlet through which molten polymer is extruded. The polymer is suitable for producing the pre-stretch film. A film producing device is spaced apart from the die. One or more coolant supplies are positioned proximate the film producing device for directing a stream of coolant onto the molten polymer positioned on the film producing device.
