High-density polyethylene (HDPE) is one of the most commonly used plastics in the United States. Labeled as #2 plastic, it is typically found in milk jugs, plastic bags and refillable plastic bottles. In addition to plastic lumber and recycled plastic furniture, recycled HDPE is used to manufacture lawn and garden products, buckets, crates, office products and automobile parts.
HDPE plastic has several properties that make it ideal as a packaging and manufacturing product. It’s stronger than standard polyethylene, acts as an effective barrier against moisture and remains solid at room temperature. HDPE plastic also resists insects, rot and other chemicals.
