DOW 310E LDPE for Blown Film Extrusion

DOW 310E is a low density polyethylene (LDPE) resin developed for blown film extrusion applications. This grade features a balanced combination of excellent processability, good drawdown capability, and reliable mechanical performance. It can be used as a standalone resin or blended with LLDPE to enhance film toughness, flexibility, and overall performance.

LDPE 310E is designed to provide stable bubble formation, smooth extrusion behavior, and consistent film quality, making it suitable for a wide range of flexible packaging and industrial film applications.
