What is the monomer of polythene bag?

The monomer of a polythene bag is ethylene, which is a simple hydrocarbon with the chemical formula C2H4. During the polymerization process, these ethylene monomers link together to form polyethylene, the polymer that makes up polythene bags. Polyethylene can have different densities and properties depending on the specific polymerization process used, leading to variations like low-density polyethylene (LDPE) and high-density polyethylene (HDPE).
