Bimodal high density polyethylene resins are widely used for the production
of thin, stiff, paperlike films. The film thickness is less than half that
of low density polyethylene films for the same application, leading to a s
ubstantial reduction of raw material consumption. The processing behaviour
of high density polyethylene can be tuned to give excellent processibility
and particularly bubble stability, to compete with the processibility of lo
w density polyethylene, allowing the possibility of producing thin films wi
th very good quality consistency at high production rates. PRCPA/1426. (C)
