Recalcitrant nature of plastic is due to its high molecular
weight, complex three-dimensional structure, and hydrophobic
nature, all of them hampers its availability to microorganisms
(Hadad et al. 2005). Plastics include polythene, propylene,
polystyrene, polyurethane, nylon etc. Polyethylene either
LDPE (low density polyethylene) or HDPE (high density
polyethylene) is a thermoplastic polymer made by monomers
of ethylene, used mostly as thin films and packaging sheets
(Kumar et al. 2013). Among these LDPE materials are strong,
light-weight and durable thus are having wide uses.
