LDPE 1820
ExxonMobil / Premium Origin
LDPE 1820 is a high-performance low density polyethylene resin characterized by its ultra-low melt index (0.18 g/10min) and robust mechanical properties. It is primarily used for heavy-duty industrial blown films and high-strength agricultural laminations, offering exceptional puncture resistance, high Elmendorf tear strength, and superior structural integrity for demanding load containment.
