Linear low density polyethylene. Computer artwork showing the molecular chains of the hydrocarbon polymer linear low density polyethylene (LLDPE). The atoms in the molecule are colour coded: carbon (light green and mauve) and hydrogen (pink & blue). C2H4) with small amounts of another unsaturated hydrocarbon (CnH2n where n is 4 to about 10). The chains in LLDPE are far more branched then those of standard polyethylene. This means that the LLDPE chains are far less inclined to slide over each other under making it ideal for films, sheets and bags.
