PROBLEM TO BE SOLVED: To provide a pulp containing a pulp as a main component, which is suitable for press molding, which has good moldability in which cracks and unevenness of folding wrinkles do not occur during press molding and high productivity. To provide a molded base paper. Further, the present invention provides a paper drawn container (deep drawn container) applicable to applications such as relatively deep trays and cups. In particular, the present invention provides a paper drawn container having excellent flange smoothness. In addition, it is deep drawn, It is lightweight and does not cause blistering or blistering of the container. Provide a highly rigid paper container. A base paper that satisfies the following four conditions: Tensile strength (JIS-P8113) is 2.0 kN / m that's all. Elongation at break (JIS-P8113) is 1.5% or more. Critical compressive stress defined by the following equation is 1 to 10MP a range. Critical compressive stress = A / B where A indicates the compressive strength according to JIS-P8126, and B indicates the load area of the test piece at the time of measuring the compressive strength. The amount of compressive deformation when a compressive stress of 20 kgf / cm 2 is applied in the thickness direction is 10% or more. |
