A molding base paper used for forming paper vessels such as a cup or tray for foods and various industrial products is disclosed which satisfies the following conditions (1) to (4): (1) a tensile strength (JIS-P 8113) of at least 2.0 kN/m, (2) an elongation at break (JIS-P 8113) of at least 1.5 %, (3) a critical compression stress, defined by the following formula, in the range of 1 to 10 MPa: <DF>critical compression stress = A/B </DF> wherein A represents the compression strength determined by JIS-P 8126, and B represents the area of loaded part of the test piece in the determination of the compression strength, and (4) an amount of the compression deformation, caused by applying compression stress of 20 kgf/cm<2> in thickness direction, of at least 10 %. <??>The paper vessels are prepared by controlling the water content of the molding base paper at 10 to 20 % and then drawing the molding base paper at 100 to 150 DEG C. |
