The vast majority of plastic pallets
are made from HDPE (high density polyethylene) and PP (polypropylene), and recycled HDPE and PP. The distinction between virgin resins and recycled resins is immensely important.
When plastic is modified in processing it undergoes heat and pressure. Heat is required to liquefy the plastic to mold it, and pressure is required to form the liquid into an acceptable and consistent shape. The application of heat and pressure puts strain on the molecular structure of the plastic, and the more times this occurs, the weaker the molecular structure becomes.
Virgin resins are typically more durable on the molecular level than recycled resins, and they perform better when put through the correct design and processes.
