Abstract
AbstractMetallocene catalysed polyethylenes are the latest addition to the polyethylene family and are reported to have superior mechanical properties over conventional polyethylenes. This paper sought to investigate the effect of blending these materials with conventional low density polyethylene for use in thin films, suitable as packaging materials and produced by the blown film process. Two grades of Metallocene catalysed polyethylene were used in the study. Films containing increasing percentages of these resins were produced at various processing conditions and their mechanical properties considered. These films were then characterised using Differential Scanning Calorimetry and Dynamic Mechanical Thermal Analysis techniques. This work showed that increasing the percentage of metallocene catalysed polyethylene in a low‐density polyethylene film improved the mechanical properties of the resultant film.
