I. Physical property: The LLD/HD polyethylene resin powder is colorless, odorless and nontoxic white powder without surface luster. LLDPE is mixed with additives for granulation to obtain a granular product. The granular product is a lenticular or cylindrical grain, the grain size is 3.2~5mm (D)×2~3mm (L) (calculated as per extruder die hole size), and the water content is ≤0.05 percent (wt).
II. Quality index: GB/T15182-94
