Description

Pit paperboard with good buffering property Technical Field The application relates to the field of paperboards, in particular to a pit paperboard with good buffering property. Background The pit paper board is an environment-friendly material widely applied to the packaging field, and has good buffering performance and certain compressive strength due to the unique structural design. The pit paper board is generally made of a plurality of layers of paper through processes of bonding, pressing and the like, and at least comprises one layer of paper with a wavy or similar structure, and the structure endows the pit paper board with excellent compression resistance and buffering capacity, and the pit paper board is low in cost, easy to process, good in recoverability and environment friendliness, so that the pit paper board is widely applied to packaging of various products such as foods, electronic products and daily necessities. Conventional pit boards are typically composed of an outer corrugated board layer, which provides the main compressive strength through its corrugated structure, and an inner buffer paper layer, which is mostly corrugated kraft paper, for absorbing impact forces and protecting the articles in the package from damage. Although the traditional corrugated board has certain compressive strength, when the corrugated board receives a large impact force, the buffer paper of the inner layer is extruded and deformed, the buffer effect can not be generated any more, and the pit board can not effectively protect the articles in the package from being damaged. Disclosure of utility model The application aims to solve the problem that the pit paper board cannot effectively protect the articles in the package from damage caused by the fact that the buffer paper at the inner layer is extruded and deformed and cannot generate a buffer effect when the buffer paper receives a large impact force in the prior art. The application adopts the following technical scheme for realizing the purposes: The pit paperboard comprises a first corrugated paperboard, a second corrugated paperboard is arranged on the first corrugated paperboard, a first buffer layer is arranged between the first corrugated paperboard and the second corrugated paperboard, a second buffer layer is arranged on the first buffer layer, a reinforcing layer is arranged between the first buffer layer and the second buffer layer, and waterproof layers are fixed between the first corrugated paperboard and the first buffer layer, and between the second corrugated paperboard and the second buffer layer. Through adopting above-mentioned technical scheme, increase buffer layer one and buffer layer two between corrugated container board one and corrugated container board two, then increase the enhancement layer between buffer layer one and buffer layer two to can let pit cardboard effectively absorb and disperse external force impact, can receive the extrusion back to resume the former state simultaneously, protection packing article avoid damaging. Further, the thickness of the corrugated board I and the corrugated board II is 3mm. Through adopting above-mentioned technical scheme, utilize corrugated container board one and corrugated container board two of 3mm thickness as the surface of hole cardboard to can effectively increase the impact resistance and the intensity of hole cardboard. Further, the first buffer layer is a sponge paper layer, and the thickness of the first buffer layer is 3mm. Through adopting above-mentioned technical scheme, utilize the sponge ply of 3mm thickness as buffer layer one, utilize the sponge ply to absorb impact force to can improve the impact resistance of hole cardboard.
