LLDPE DFDA-7042 is a film-grade linear low-density polyethylene resin produced with butene copolymer technology. It is developed for flexible film manufacturing and provides stable melt flow, smooth extrusion, and consistent processing performance. The grade works well with conventional blown film equipment and supports efficient production across a range of film structures.

DFDA-7042 typically has a melt flow rate of 2 g/10 min and a density of 0.918 g/cm³. Films made from this resin offer high elongation, good Dart Drop Impact, strong tear resistance, and a typical 45° gloss of around 76. These characteristics make it suitable for packaging films, bag films, freezing films, inner liner films, agricultural films, and other general-purpose film applications.
