Linear low density polyethylene LLDPE is a substantially linear polymer polyethylene, with significant numbers of short branches, commonly made bycopolymerization of ethylene with longer-chain olefins. Linear low-density polyethylene differs structurally from conventional low-density polyethylene because of the absence of long chain branching. LLDPE has penetrated almost all traditional markets for polyethylene, it is used for plastic bags and sheets, plastic wrap, stretch wrap, pouches, toys, covers, lids, pipes, buckets and containers, covering of cables.
