摘要： PROBLEM TO BE SOLVED: To provide a paper tube for a sheet of kraft paper bag capable of preventing foreign matters from being mixed by solving problems that, when an opening part to fill content formed in the kraft paper bag is evacuated from face and back sides of the bag, a gap is generated due to insufficient suction negative pressure between a sheet of kraft paper on an outer layer and a synthetic resin-made film or the like on an inner layer if each sheet of kraft paper layer on both the face and back sides is not spot-glued though there is no problem when each sheet of kraft paper is spot-glued, air and a part of the content is mistakenly filled in the gap when filling the content, and the mistakenly filled content as foreign matters can be mixed in the content to be removed when removing the content if air is insufficiently exhausted.
SOLUTION: At least two sheets of kraft paper and a synthetic resin-made layer interposed therebetween are adhered at a large number of adhesive lines with a gap therebetween in a section of the predetermined height from a bottom of a paper tube to form a kraft paper bag, and the kraft papers and the synthetic resin-made layer between the adhesive lines are tightly attached to each other in a separate manner from each other.

摘要： PROBLEM TO BE SOLVED: To provide a kraft paper bag, which prevents the occurring of fine powder of paper material or thread by doing away with a perforated seam formed on the bottom of a kraft paper bag, enables the automatic discharge of residual gas from the paper bag upon filling it with contents, and remain strong as much as a paper bag with a perforated seam.
SOLUTION: A bottom paper slightly longer than the lower end of a bag is bent to have a longitudinal section of V-shape, and is stuck to the lower end of the bag with an adhesive. The ear of the bottom paper is projected at both sides of the lower part of the bag so as to form a gap between the bottom of V-shaped bottom paper and the lower end of the bag, and gaps between both sides of the lower part and the ear, with the gaps made communicate with each other as micro leak gaps for the gas inside the bag.

摘要： PROBLEM TO BE SOLVED: To provide a powder packaging bag that facilitates the handling of powder being packaged and also prevents spillage of the powder.
SOLUTION: In the powder packaging bag, triangular folds 3 and 4 are formed on both corners of one of sheets defining a blow-in open end of a packaging bag main body 1 formed by folding a paper tube flat, at the same time, the sheet is valley-folded along a first crease A parallel to the end line of the blow-in open end 2, and thus a rectangular blow-in opening 5 is formed. A paper valve 7, inner patch 8, or the like is placed on and attached to the vicinity of the end of the triangular fold 3. Both sheets defining the blow-in open ends 2 are mountain-folded back along a second crease B and a third crease C formed parallel to the first crease A and with the first crease A between them. Then, the turned-back folds 9 and 10 are affixed in order, thereby forming the blow-in bottom 11. The basic weights of the valve 7 and inner patch 8 are 55% to 95% of the basic weight of the base paper of the packaging bag main body 1.
