  • METALLOCENE POLYETHYLENE BLENDS FOR IMPROVEMENT OF ISBM PROCESS
    Publication number: 20240228758
    Abstract: A polyethylene-based resin composition for injection stretch blow-molding including a co-crystallized blend of a high density polyethylene (HDPE) base resin and a linear low density polyethylene (LLDPE). A method of producing a polyethylene-based resin composition includes adding the LLDPE to the HDPE base resin at a molten state to provide a blend of HDPE and LLDPE, wherein at the molten state, the LLDPE is fully miscible with the HDPE base resin and co-crystallizing the blend of HDPE and LLDPE.
