Look at HMW-LDPE Film Extrusion, 1990 Polymers, Laminations & Coatings Conference Proceedings
High molecular weight low density polyethylene (HMW-LDPE) bridges the gap between strong fractional melt index LDPE resins and clarity LDPE resins by combining significant strength with good puncture resistance and high clarity. The versatility of extrusion by either long stalk or in the pocket methods can enhance film properties for specific applications.
