Abstract
A film casting simulation has been used to demonstrate why the encapsulation extrusion process is so effective industrially in enhancing the stability of the extrusion. In the present study, it is intended to explain theoretically why and how the coextrusion of LDPE in encapsulation dies improves the HDPE process. The undesirable neck-in and draw resonance phenomena frequently occurring in the extrusion of HDPE are shown due to its low-melt-strength property, and consequently can be alleviated using high-melt-strength materials in the encapsulating dies.
