摘要： The present invention discloses a composite ribbed expanded polystyrene pallet and a manufacturing method thereof, comprising a body and a base support, said base support clads the sides and bottom of the body, said body is made of expanded polystyrene, said comprises a pallet platform and plural supporting feet. Through the above mentioned way, the present invention utilizes light-weight polystyrene to make the body, the surface is covered with a base support of high-strength engineering plastic film, and reinforcing ribs are additionally arranged inside the body through special process. The pallet of the present invention has good load bearing performance, economy and practicability. The logistics cost also can be reduced greatly. Therefore, the composite ribbed expanded polystyrene pallet and the manufacturing method thereof have broad market prospects in popularization.
