Polythene is a commercial polymer frequently used to make plastic. It is usually found in packaging such as bottles and grocery bags. There are various types of polythene categorised by their properties including their density and branching, as well as their weight. Although melting plastic is usually performed by professionals because of the dangerous fumes and hazards, you can melt small amounts of plastic at home such as a thin plastic water bottle to create customised items with the use of moulds. Melting small amounts of plastic is also an efficient means of recycling.

    Place a small amount of plastic in the container. Position the metal container in the toaster oven.
