The bottom of the bag body is respectively provided with a folding line for forming at the connecting position of the front bag surface and the rear bag surface, and a folding pair folding line for superposition is arranged at the bottom of the bag body.

The M-shaped insert edge comprises a first inner edge which is arranged on one side edge of the front bag surface and a second inner edge which is arranged on one side edge of the rear bag surface, wherein an outer edge is arranged on the first inner edge, and the outer edge is adhered with the second inner edge.

The intersection of the first inner folded edge and the bottom of the bag body and the intersection of the second inner folded edge and the bottom of the bag body are respectively provided with a diagonal crease line for molding.

The bonding part is arranged on the inner side surface of the sealing flanging.

The bonding part is arranged on the outer side surface of the sealing flanging, and crease lines for the flanging are arranged at positions of the corresponding upper bag surface and the lower bag surface, which are adjacent to the bag openings.

And a film coating layer or a bubble layer is arranged on the inner side surface of the paperboard for forming the paper bag.

Handles matched with each other are respectively arranged on the front bag face and the rear bag face.

The improved paper bag has the beneficial effects that the improved paper bag adopts the integrated bag bottom to improve the bearing capacity and avoid damage, adopts the M-shaped inserting edge to increase the loading capacity and the three-dimensional sense of the bag body, and adopts the sealing flanging to facilitate the rapid sealing of the bag body.
