Description

Technical Field

[0001] The utility model belongs to the technical field of cartons, and in particular relates to a moisture-proof and air-permeable carton. Background Art

[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. Traditional cartons do not have a moisture-proof structure at the bottom. The bottom of the carton is easily penetrated by external moisture, causing the carton to deform, break, or even damage the items, and easily causing the stored materials to be damaged by moisture. Most of the existing technologies improve the waterproof performance of the carton by laminating, but the air permeability of the laminating carton is poor. When transporting products such as fruits, it is easy to cause the internal products to deteriorate and rot. Therefore, a moisture-proof and air-permeable carton is now provided, which is not only moisture-proof when storing materials, but also has good air permeability. Utility Model Content
