DOW LDPE™421E low density polyethylene resin can be extruded by ordinary blown film process, and the melt temperature is between 160 and 195°C. When prepared, this resin has excellent mechanical properties even at a higher density (high stiffness) than a standard resin, while maintaining very high transparency and gloss. This resin has good drafting and processability. This product does not contain slip agent or opening agent.
