Abstract
Die lines in plastics extrusion are annoying surface striations that can de stroy extrudate aesthetics and compromise product properties. Here, the ava ilable literature on die lines is reviewed to explore how die lines arise a nd how to minimize them. Many factors influence die line formation, and the re are a few ways to suppress them. Future study on die lines should includ e the non-Newtonian fluid mechanics of the polymer melt.
