PROCESS FOR REDUCING SURFACE MELT FRACTURE DURING EXTRUSION OF ETHYLENE POLYMERS

摘要

- 33 -PROCESS FOR REDUCING SURFACEMELT FRACTURE DURING EXTRUSION OFETHYLENE POLYMERSABSTRACTMelt fracture of films made from LLDPEresins is reduced by using a die having a die landregion fabricated from stainless steel and whereinthe length of the die land to the width of the diegap is about 35:1 to about 60:1.
