Linear low-density Polyethylene (LLDPE)

    
Linear low-density polyethylene (LLDPE) is a substantially linear polymer (polyethylene), with significant numbers of short branches, commonly made by copolymerization of ethylene with longer-chain olefins.

Linear low-density polyethylene differs structurally from conventional low-density polyethylene (LDPE) because of the absence of long chain branching.

The linearity of LLDPE results from the different manufacturing processes of LLDPE and LDPE.
