Produce trays

When using 100% HDPE, Tray-Pak Corporation was experiencing significant warpage, inefficient processing, and poor material distribution in fresh produce trays.

Working with NOVA Chemicals, the UPESTM resin supplier and Primex, the sheet producer, Tray-Pak engineered a better fresh produce packaging solution. The new tray delivered the perfect balance of performance and cost while meeting sustainability objectives.

Benefits when using a UPES/HDPE blend include 20% source reduction, 22% faster forming rates, enhanced part definition, shorter start-ups, and reduced scrap rates; all while significantly improving material distribution and achieving 24% higher crush strength.
