Low density polyethylene (LDPE).
This clear or translucent plastic exhibits flexibility, chemical resistance, and waterproofing capabilities. It is used in the manufacture of a wide range of products, including grocery bags, plastic wrap and film, flexible packaging material, and injection molded parts.
High density polyethylene (HDPE).
HDPE offers greater rigidity and durability than LDPE. It is available in translucent to opaque variation and displays excellent chemical resistance. Products made from HDPE include rigid packaging containers, toys, outdoor furniture and structures, kitchen equipment, and plumbing pipes.
