Polyethylene or polythene is the most common plastic in use today
• The primary uses of polyethylene are in packaging film, garbage bags, grocery bags, insulation for wires and cables, agricultural mulch, bottles, toys, and houseware. Polythene is also used in trays, fruit juice containers, milk containers, crates, and food packaging products.

• HDPE is also used in ropes, fishing nets, agricultural nets, and industrial fabrics. It is not uncommon for this plastic to be used in wirings and cables as well
• Low-density polyethylene (LDPE) is widely used in the production of squeeze bottles, garbage bags, laminations, and food packaging due to its high flexibility and low cost.
• LDPE is also used in pipes and fittings. It is ideal for such applications due to its low water absorption and also due to its plasticity
