Description

Dampproofing carton of flexible support
Technical Field
The invention relates to the field of cartons, in particular to a flexibly supported moisture-proof carton.
Background
The paper board is made into the corrugated case through die cutting, indentation, nailing or gluing. The corrugated case is a packaging product with the widest application, and the use amount is always the first of various packaging products. Comprises a calcium plastic corrugated case. For more than half a century, corrugated cartons gradually replace transport packaging containers such as wooden boxes and the like with excellent service performance and good processing performance, and become the leading force of transport packaging. It not only protects the goods, is convenient for storage and transportation, but also beautifies the goods and publicizes the goods. The corrugated case belongs to green environmental protection product, and it does benefit to the environmental protection, does benefit to the loading and unloading transportation.
The existing cartons are generally made of paperboard through cutting and pressing. However, the paperboard has a general problem that the exterior of the paperboard is usually treated with water-proofing, but the interior of the paperboard is not treated with water-proofing, and the water-proofing performance is poor, and the paperboard is generally formed by alternately bonding flat paperboard and corrugated paperboard, which can increase the strength of the paperboard to a certain extent, but also increase the surface area, and form large gaps between the flat paperboard and the corrugated paperboard, so that the interior of the paperboard is easy to absorb moisture or water, and the paperboard structure is easy to collapse and has low strength after being wetted or exposed to water.
