LLDPE for Blown Film
The most widely used linear low-density polyethylene grade from leading Chinese mills, a butene-1 copolymer designed for blown film extrusion. With MI ~2.0, LLDPE 7042 offers excellent processability, good optical properties, and superior puncture resistance compared to LDPE. The workhorse grade for packaging bags, agricultural film, and lamination applications across Asia, Africa, and South America.
