PROBLEM TO BE SOLVED: To prevent the transfer of paste onto a gripping string to be installed on a bag mouth in a mouth folding process for a paper handbag. SOLUTION: A mouth folding section 5 is formed on the upper edge of a paper bag base paper, and a first pasting section 8 for sticking the mouth folding section 5 is formed on the whole width of the base paper 1A. A second pasting section 9 is formed on a section of the mouth folding section 5 corresponding to a reinforcing mounting paper 3 of a gripping string 4 stuck on a pasting section 8. The second pasting section 9 is formed across a pair of cuts 7 into which the gripping string 4 is inserted through, and a non-sticking section 20 is formed on bending sections 7B of the cuts 7 being in contact with the gripping string 4. A third pasting section 25 corresponding to the non- sticking section 20 is formed on the reinforcing mounting paper 3 of the gripping string 4 stuck on the first pasting section 8. The paste of the first pasting section 8 is not transferred onto the gripping string 4 by the arrangement when the mouth folding section 5 is folded to the inner side, and the mouth folding section 5 is not released and stuck firmly after mouth folding. |
