Abstract: The present invention is a method and apparatus for quick and easy rubber sleeve exchanges on chill rolls, such as are used in film extrusion processes. The apparatus includes chill roll or mandrel, a rubber sleeve covering the exterior face of the mandrel, an automated cantilever system, and an air booster. The rubber sleeve is easily removed by tilting the mandrel and inserting a layer of air between the rubber sleeve and the mandrel, thereby allowing the sleeve to slip off the mandrel and allowing for a new rubber sleeve to be placed onto the mandrel.

Abstract: The present invention is a method for forming a laminate for use as a flexible packaging wrapper for confections and other food bars. An outer clear film usually oriented polyolefin is printed, preferably reverse printed, with graphics. In a tandem extrusion lamination with registered cold seal process a molten, polyolefin extrudate is applied to bond the outer printed film to an inner film. The inner film is preferably oriented polyolefin and may have a metallized coating of aluminum buried against the extrudate. Finally, a pattern of cold seal adhesive is applied to the inner film surface. The flexible package made with the extrusion lamination process offers improved stiffness, puncture resistance, abrasion resistance and durability over a similar structure produced with adhesive lamination.
