A Guide to Polyolefin Film Extrusion - LyondellBasell
www.lyondellbasell.comFor homopolymer polyethylenes, the higher the resin density, the higher the degree of crystallinity. High density PE resins have molecular chains with comparatively few side chain branches. This allows the chains to pack more closely together. The result is crystallinity up to 85%. Low density PE resins generally have crystallinity from 35 to 55%.
