The use of encapsulation dies for processing linear polyolefin resins

摘要

Traditionally highly branched autoclave low-density polethylene resins have been ideal for extrusion coating due to their inherent melt strength characteristics. Encapsulation coating dies have been used with other polymers to overcome melt strength deficiencies and improve processing. This study evaluates the effectiveness of encapsulation with linear materials such as high-density polethylene and linear low-density polyethylene.
