PE, or polyethylene, is a versatile and environmentally-friendly type of plastic. Manufacturers  produce PE by polymerizing ethylene gas, which creates long chains of polymer molecules. These chains give PE its high tensile strength and flexibility, making it ideal for use in a wide range of applications. Additionally, PE is resistant to moisture and chemicals, making it a popular choice for packaging products such as food, beverages, and personal care items. Its environmental benefits include being recyclable and lightweight, which reduces transportation emissions.
