A high-density polyethylene (HDPE) Hostalen GX4041 for blow-thinning shows the balance between its rigidity and impact resistance. The high-density polyethylene can be used for composite films, tear films, synthetic papers, labels and heavy bags. The Hostalen GX4041 is already in the early stages of the development of Basel Polyolefins. The film obtained from a resin with a density of 0.957 g/cm3 and a melt flow rate of 0.38 has a tensile strength of 37 MPa in the machine direction (TD) and a tensile strength of 35 MPa in the transverse direction (TD). It is 400% in the longitudinal direction and 480% in the transverse direction, and has a piercing strength (MD/TD) of 300/420 mN and a drop weight impact strength of 270 g. The product test report shows that the drop impact strength of the GX4041 is 30%~40% better than that of the existing GM9255F2 class. According to reports, this HDPE also has superior blown film processing stability, a very low gel content, and a good appearance under high yield. The films produced therewith have a very wide processing range, good planarity and a superior film configuration.
