The long side-by-side polymer chains in high-density polyethylene (HDPE) impact its properties. Plastic bags made from HDPE are lightweight, flexible, and sturdy. They are waterproof and resistant to temperature extremes. HDPE is relatively inexpensive to make, so plastic bags are a low-cost way to transport foods and other goods.
