With the improvement of people's environmental awareness, more and more people are beginning to use paper packaging bags, which can reduce energy consumption and waste emissions. Paper packaging bags have good recyclability and are conducive to reducing environmental pollution.

[0003] The shortcomings of the prior art: Most of the paper packaging bags in the prior art are made of kraft paper, recycled paper, special paper, etc., which have good toughness. Therefore, it is difficult to fold the paper packaging bags into a suitable size. Repeated folding of the paper packaging bags will form deep creases on the surface of the packaging bags. After repeated folding, the paper packaging bags are easily damaged. In addition, the folded paper packaging bags will unfold due to the toughness of the paper itself, occupying a large space, which is not conducive to the storage of paper packaging bags.
