Kulpack paper

摘要

Provided is a kurpack paper having excellent elongation characteristics and strength characteristics so that when the kurpack paper is processed into a bag, the bag is less likely to be broken. In a gap former type paper machine equipped with a kulpack device, the specific tensile energy absorption in the longitudinal direction specified in JIS P8113 is 2.5 J / g or more and the specific tensile energy absorption in the transverse direction is 1.0 J / g. Kurupak paper manufactured as described above. Excellent strength characteristics in vertical and horizontal directions, especially in the vertical direction.
