[0005] In order to solve the problem mentioned in the above background technology, a packaging box includes an outer layer of the box body and a first inner layer. The surface of the first inner layer is fixedly connected to the side of the outer layer of the box body, and a first tear strip is provided on the side. A plurality of parallel ventilation holes are provided on the side of the first inner layer facing the first tear strip to achieve ventilation of the packaging box.

[0006] In this way, the ventilation hole is arranged on the surface of the first inner layer and covered in the first tear strip. A pull strip is arranged above the first tear strip. The user can tear off the first tear strip by pulling the pull strip to expose the internal ventilation hole to the outside, so that the interior of the packaging box is connected with the outside and the internal and external air flows interact. It is worth mentioning here that in the implementation method provided in the embodiment of the present application, the packaging box is used to store solid food, etc., and the first inner layer arranged on the side is arranged on the outer layer of the inner cavity where the food is stored. This is conducive to air circulation in the packaging box, so that the environment in the packaging box remains dry and cool, and the food in the packaging box is prevented from directly contacting the air and causing deterioration or moisture.

[0007] According to an implementation provided in an embodiment of the present application, the first tear strip includes a first lock tongue, which is arranged on a side of the first tear strip close to the first inner layer, and the first lock tongue corresponds to the ventilation hole one by one.

[0008] With this arrangement, a fold is provided on the first tear strip. When the user pulls down the first tear strip, the user can control the tearing length as needed, and the fold is correspondingly provided below each first lock tongue and on the side opposite to the first lock tongue. After tearing off the first tear strip, folding it along the fold is both beautiful and saves space. In addition, the first lock tongue and the ventilation hole are correspondingly fastened to avoid the first tear strip on the side of the packaging box being damaged due to bumps during transportation.

[0009] According to an embodiment provided in an example of the present application, the outer layer of the box body includes a box cover and an inner cavity.
