The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] The following description, in conjunction with the accompanying drawings, describes an embodiment of the present invention: a fruit and vegetable transport packaging box that enhances freshness preservation.

[0019] like Figures 1-4 As shown, the fruit and vegetable transport packaging box with enhanced preservation provided in this embodiment of the utility model includes a carton body 1, a breathing seat assembly 2, and an air cushion assembly 3. The carton body 1 includes a face paper layer 11, a corrugated paper layer 12, and a heroin paper layer 13. The face paper layer 11 is located on the outer side of the carton body 1, and the corrugated paper layer 12 is located between the face paper layer 11 and the heroin paper layer 13. The breathing seat assembly 2 is located on the top of the carton body 1 and includes a breathing hole 14 located on the top of the carton body 1. A cover plate 21 is provided on the top of the breathing hole 14, and a filter unit is provided inside the breathing hole 14. The air cushion assembly 3 is located on the inner wall side of the carton body 1.

[0029] In one embodiment of this utility model, such as Figure 3 As shown, the filter unit inside the breathing hole 14 consists of a molecular membrane layer 23 and an activated carbon layer 25. The molecular membrane layer 23 is made of a molecular thin film, and the activated carbon layer 25 is made of activated carbon particles. The adsorption function of activated carbon is used to remove the odor that the fruit may produce. The molecular membrane layer 23 filters microorganisms and harmful substances in the air, thereby further preserving the fresh products while reducing the odor that may occur during transportation.

[0030] In one embodiment of this utility model, such as Figure 4 As shown, the air cushion base 31 can be attached to the inner wall of the carton body 1, and the bubble pad 32 can form air pressure buffer after being impacted, thereby absorbing and dispersing external force, reducing the stress on the items, and reducing the damage rate during transportation. The air cushion base 31 is also provided with air holes 33 to allow airflow in the carton body 1 and reduce gas accumulation.

[0031] In summary, this utility model overcomes the problems of traditional express packaging, where some poor packaging leads to easy damage and rot of fruit during transportation, and some excessive packaging leads to resource waste.

[0032] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
