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. regulatory requirements: DOW LDPE 421E low density polyethylene resin shall meet the following regulatory requirements: us food and drug administration regulation 21 CFR 177.1520(c)2.2 EU, No 10/2011 please consult the regulations for complete details.
