[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] Referring to Figs. 1-4 In the embodiment of the utility model, a kind of inner bag paper box for food packaging, including carton 1, inner bag 2, inner bag 2 is connected to the inner side of carton 1, the inner side of inner bag 2 is provided with inner support assembly 3, inner support assembly 3 is used to provide support for the inner side of inner bag 2, while realizing the limiting compression operation of inner bag 2 and carton 1;

[0025] Inner support assembly 3 includes bottom support frame 301, concave column 302, top support frame 303;

[0026] Bottom support frame 301 is attached to the inner side bottom of inner bag 2, for realizing the compression of the bottom of inner bag 2;

[0027] Concave column 302 is installed on the top of bottom support frame 301 and is attached to the inner side of inner bag 2 around, for the compression of the inner side of inner bag 2 around;

[0028] Top support frame 303 is installed on the top of concave column 302, for the bottom protection of food placed in inner bag 2;

[0029] Bottom support frame 301 top is provided with plug-in interface 304 for the insertion of concave column 302, and plug-in interface 304 is completely penetrated to the bottom of bottom support frame 301, and the bottom of concave column 302 is provided with docking interface 305 for the insertion of plug-in interface 304;

[0030] Plug-in interface 304, docking interface 305 and concave column 302 are evenly provided with multiple groups along the inner wall trajectory of carton 1;

[0031] Bottom support frame 301 and concave column 302 are formed with multiple straightly distributed "concave" crosspieces, which cooperate with multiple concave columns 302 to increase the compression resistance of carton 1.

[0032] In the embodiment, the inner bag paper box is used as follows when in use:

[0033] First, inner bag 2 is connected to the inside of carton 1, and the top edge of inner bag 2 is folded and wrapped on the top edge of carton 1.
