Abstract

Abstract This patent discloses an improved lightweight, recyclable, nearly completely paper pallet. The pallet is made of a Honeycomb paper base and Honeycomb paper support runners or blocks. The blocks are protected and significantly strengthened by a rigid paper cap. The base, runners, blocks, and cap may also have a protective liner, such as polyethylene, or be otherwise treated to enhance water and moisture resistance.
