LDPE (Low-Density Polyethylene) is a lightweight, flexible thermoplastic polymer characterized by its branched molecular structure, which gives it softness, clarity, and ease of processing. It offers excellent impact resistance, moisture resistance, and chemical stability, making it ideal for film applications. LDPE is non-toxic, food-safe, and recyclable, though it has lower tensile strength and heat resistance compared to HDPE and LLDPE. Its versatility, cost-effectiveness, and ease of fabrication make it one of the most widely used plastics in packaging and consumer goods.
