Polyethylene is one of the most widely produced synthetic thermoplastic polymers, formed through the polymerization of ethylene monomers. Its physical properties, including flexibility, durability, and chemical resistance, allow it to be processed into a vast array of usable forms. The material exists in various densities, such as high-density polyethylene (HDPE) and low-density polyethylene (LDPE), which exhibit differences in rigidity, transparency, and tensile strength. Due to its low cost and versatility, polyethylene is extensively utilized across industrial applications, including the manufacturing of packaging films, containers, piping systems, and protective sheeting.
