Figure 1: The linear form of polyethylene, known as high-density polyethylene (HDPE).
High-density polyethylene (HDPE) is a linear, highly crystalline synthetic resin known for its high strength and moderate stiffness. Because of its ability to withstand repeated exposure to temperatures up to 120 °C (250 °F), it is suitable for applications requiring sterilization.12
Common products manufactured from HDPE include:
- Blow-molded items: Bottles for milk and household cleaners.13
- Blow-extruded materials: Grocery bags, construction film, and agricultural mulch.12
- Injection-molded goods: Pails, bottle caps, appliance housings, and toys.32
HDPE is identified by the plastic recycling code number 2.12
