A twin sheet plastic panel structure (10), a twin sheet plastic pallet utilizing the panel structure, and a methodology for forming the panel structure and pallet. The panel structure (10) is formed by thermoforming an upper plastic sheet (14) to include rows of hollow bosses extending downwardly from the sheet; thermoforming a lower plastic sheet (16) to include rows of hollow bosses extending upwardly from the sheet; and bringing the sheets together while still in a heated flowable state to position the bosses of the upper sheet in intermeshing relation to the bosses of the lower sheet so that the annular side wall portions of the upper and lower bosses fuse together, the bottom walls of the upper sheet bosses are fused to the upper surface of the lower sheet, and the upper walls of the lower sheet bosses are fused to the lower surface of the upper sheet. |
