Low-density polyethylene (LDPE) is a type of plastic known for its flexibility and durability. It is commonly used in products like plastic bags, containers, and packaging films. LDPE is made from the polymerization of ethylene, a simple hydrocarbon, which gives it a low-density structure that contributes to its lightweight nature. LDPE is resistant to impact and moisture, making it suitable for various applications. It is also recyclable, although it is less commonly accepted in recycling programs compared to other plastics like high-density polyethylene (HDPE). LDPE's properties make it a popular choice in the packaging industry.
