WebAug 1, 1999 · Film extrusion conditions, including blow-up ratio (BUR), frost-line height, and gauge all affect WVTR of PE films made from resin with broad-MWD or long-chain branching. As the frost-line goes up, the WVTR decreases (moisture barrier improves). This effect on a broad-MWD HDPE is enhanced as blow-up ratio increases.
