What is the function of Honeycomb Pallets? Because honeycomb paperboard has good flat compressive properties, it can be used for upper and lower decking in pallets, and can also be used as longitudinal beams or pads for pallets. At this time, it is necessary to combine several layers of thicker honeycomb cardboard according to the standard size of the stringer or spacer, which means that the entire Honeycomb Pallet is only made of honeycomb cardboard.
