Regardless of the cold water extraction PH (JIS P-8133) is 6.5 ~
Even with neutral paper in the range of 9.0, the photographic properties were all poor. Therefore, unbleached kraft paper cannot be used so as to be in contact with the photographic light-sensitive material, and as shown in JP-A-62-53829, it has been formed into a double bag and used as its outer paper.
また、未晒クラフト紙の写真性を良好にするために、
