In the attached drawing 3, the planar PP laminated paper 0201 with 270mm width is unfolded, the surface facing the observer is the PP laminated layer surface, the surface is the inner wall surface after the paper bag roll 2 is formed, and the left boundary line 02011 and the right boundary line 02012 are parallel to the length direction of the paper bag roll 2 and are the left boundary and the right boundary with 270mm width of the planar PP laminated paper 0201 before the paper bag roll 2 is formed.

Step 2, depending on an embodiment shown in the attached drawing 1, the unfolding used for the paper bag roll forming 2 in the single-folded-edge PP laminated paper bag roll packaging is flat PP laminated paper 0201 on the left side and the right side, and the PP laminated paper is folded inwards for 180 degrees and formed once, wherein schematic diagrams are shown in attached drawings 4 and 5:

the left side and the right side of the planar PP laminating paper 0201 are unfolded and folded 180 degrees into the PP laminating paper relatively to form a left folding line 02021 and a right folding line 02022 in one step. 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;

after the folding forming, overlapping of 10mm in width is realized by the left side and the right side of the PP laminating paper 0201 with left and

right boundary lines

02011 and 02012 as boundaries, and meanwhile, the PP laminating layer surface of the PP laminating paper 0201 becomes the inner wall surface after the folding forming.

Step 3 is based on an embodiment shown in the attached drawing 1, namely, the PP laminating paper 0201 used for forming the paper bag roll 2 in the single-folded PP laminating paper roll package is folded by 180 degrees to complete heat sealing back sealing, and the schematic diagram is shown in the attached drawing 6:

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 sealed barrier of the upper and lower adjacent heat sealed lateral seal regions 020512 isolates the no input fill region 020521 from the external environment; 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.

After the 501 th heat-sealed lateral seal 020512 is heat-sealed, the heat-sealed lateral seal 020512 is left and cut at a distance of 10mm from the heat-sealed lateral seal 020512 to form another paper bag roll end 02001.

Step 5 is based on an embodiment shown in the attached figure 1, namely, after the PP laminating paper 0201 used for forming the paper bag roll 2 in the single-folded PP laminating paper bag roll packaging is formed by heat sealing and transverse sealing at equal intervals, the PP laminating paper 0201 is wound and rolled on the inner core 1 to form the paper bag roll 2, so that the paper bag roll 2 and the inner core 1 are made into a complete paper bag roll package, and the schematic diagram is shown in the attached figure 8:
