High-Density Polyethylene (HDPE)
Polyethylene is the most common plastics in the world, but it’s classified into three types: High-Density, Low-Density and Linear Low-Density. High-Density Polyethylene is strong and resistant to moisture and chemicals, which makes it ideal for cartons, containers, pipes and other building materials.
Examples: Milk cartons, detergent bottles, cereal box liners, toys, buckets, park benches and rigid pipes.
