High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is actually a very popular engineering plastic and is sometimes confused with other similar materials. HDPE is normally available in two grades, 300 grade and 500 grade. The higher number denotes the density of the material and can improve on performance. HDPE is often chosen because of its FDA approval and food contact suitability and its excellent machine ability. The majority of HDPE is available in either black or white although 500 grade sheet is available in a range of colors, which can sometimes help with food preparation or process identification.
