By adopting the laser cutting mode, the easy-to-tear line 02023 can be only generated on the outer layer of the PP laminating paper 0201 (namely the non-inner wall surface of the paper bag roll 2 after forming), and the inner wall surface of the paper bag roll 2 still keeps intact.

The left and right hemline lines 02021 and 02022 are parallel to each other, are consistent with the length direction of the paper bag roll 2, and have the same distance of 70mm from the left and right boundary lines;

In the process of forming the paper bag roll 2, the front and rear inner wall surfaces of the paper bag roll 2 in the heat-seal transverse seal regions 020512 are completely heat-sealed by heat bonding, and in the forming of the paper bag roll 2 of the present example, heat bonding is realized in 501 heat-seal transverse seal regions 020512.

After heat-sealing and transverse sealing, the area between the upper and lower adjacent heat-sealing transverse sealing areas 020512 becomes an input-free filling area 020521; the non-input filling areas 020521 are arranged in parallel at equal intervals in the length direction of the paper bag roll 2, and the interval distance is 10 mm; the no-input fill areas 020521 are 164mm in height and 500 in number.

After heat bonding of the 1 st heat-sealed lateral seal 020512, the heat-sealed lateral seal 020512 was left and cut at a distance of 10mm from the heat-sealed lateral seal 020512 to form a paper bag roll end 02001.

Step 7 is based on an embodiment shown in the attached drawing 1, namely, the single-folded-edge PP laminated paper bag roll package with the easy-tearing line is formed, a single paper bag is torn off from the paper bag roll package edge at the easy-tearing line 02023 on the paper bag roll 2 to form a paper bag with an opening at one end, and the schematic diagrams are shown in the attached drawings 10 and 11:
