A new HDPE resin for blown film boasts a combination of stiffness and impact required for applications such as lamination film, release film (bitumen film), paper-like film, labels, bags, and heavy-duty sacks. Hostalen GX4041 is available for pre-marketing from Basell Polyolefins, Elkton, Md. Film made with this 0.957-g/cc, 0.38-MI grade has tensile strength of 5366 psi MD and 5076 psi TD; ultimate elongation of 400% MD and 480% TD; Elmendorf tear strength of 300/420 mN (MD/TD), and dart impact of 270 g. Production trials reportedly show GX4041 can provide 30% to 40% better dart impact than the current grade, GM9255F2. This HDPE reportedly runs at high output rates with excellent bubble stability, very low gel levels, and homogeneous appearance. It is also said to produce film with a very broad converting window, good layflat properties, and excellent roll configuration.
