[0021] The following will describe in detail the technical solutions provided by the embodiments of the present application in conjunction with the drawings.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution for a highly breathable paper packaging bag:

[0023] A highly breathable paper packaging bag, comprising a breathable packaging paper bag 2, the breathable packaging paper bag 2 includes a composite breathable layer 10, breathable kraft paper 11 and a breathable plate 9. The outer surface of the breathable plate 9 is fixedly connected to the inner wall of the breathable kraft paper 11, and the outer surface of the breathable kraft paper 11 is fixedly connected to the inner wall of the composite breathable layer 10. A buffer plate 8 is provided inside the breathable packaging paper bag 2. Two anti-slip blocks 12 are fixedly connected to the bottom surface of the buffer plate 8. A set of micropores 13 are provided on the inner wall of the breathable kraft paper 11; specifically, through the design of the anti-slip blocks 12, it is convenient to achieve the purpose of anti-slip. At this time, by using the design of the buffer plate 8, it is convenient to relieve the collision of food and can protect the food. At this time, according to the design of the breathable plate 9, composite breathable layer 10, micropores 13 and breathable kraft paper 11, it is convenient to play a role in ventilation, and can maintain the freshness and taste of food. Since the micropores 13 are small, liquid water can be blocked and ventilation will not be affected, which is beneficial for current use;

[0024] In this embodiment, a drawstring 7 is provided inside the breathable packaging paper bag 2. The bottom end of the drawstring 7 is fixedly connected to the upper surface of the buffer plate 8; connecting ropes 4 are provided in front of and behind the breathable packaging paper bag 2.
