    • PROBLEM TO BE SOLVED: To provide a parts packing tray capable of supporting in a stable manner a stacking load applied when the trays are stacked up in multi-stages and showing a superior shock-absorbing effect when the stored parts strongly abut against the trays due to shock or vibration applied during their transportation.
      SOLUTION: There is provided a packaging tray 1 molded by a thermoplastic resin foam sheet having at least one storing recess 3 in which the packaging tray can be stacked up in multi-stage manner under a state of storing some parts (b) in the storing recess 3. The tray 1 has some stack portions 5 for use in stacking up the trays and at least upper surface part 5a and lower surface part 5b of the stack portions 5 and they are molded under a high density with a density difference of 0.1 (g/cc) or more against the storing recess 3.
