Abstract
An improved structure of an environmental friendly coffin including a lid, faceplates, a U-shaped coffin body, and a reinforcing bottom board made from kraft boards formed by adhering multiple layers of kraft together and applying thermal pressure thereto. Wooden frames are fixed to the four sides of the coffin to reinforce the pressure-resistance and shear-resistance of the coffin. Both the manufacturing cost and timber material can be greatly reduced. Besides, burning of the coffin will not cause environmental pollution.
