Description

High-strength composite corrugated board Technical Field The utility model relates to the technical field of composite corrugated boards, in particular to a high-strength composite corrugated board. Background The corrugated paper is a plate-like article formed by bonding a face paper and corrugated paper having a corrugated shape formed by corrugating a corrugated roll. The invention and application of the corrugated paper have a history of more than one hundred years, have the advantages of low cost, light weight, easy processing, high strength, good printing adaptability, convenient storage and transportation and the like, more than 80 percent of the corrugated paper can be recycled, can be used for packaging food or digital products, is relatively environment-friendly and wide in application, is a multi-layer adhesive body, is formed by at least one layer of wavy sandwich paper and one layer of paperboard, has high mechanical strength, can resist collision and falling in the transportation process, is widely applied to paper product outer packages at present due to the characteristics of the sandwich paper and the paperboard and the structure of the paper box, has the advantages of simplicity in processing, light weight, high strength, easiness in storage and the like, is more and more popular with outer packaging enterprises, and is widely used for containing, storing and transporting food or digital products in the market. Aiming at the prior art with the patent number of CN213056252U, a high-strength composite corrugated board is disclosed, which comprises a first composite board layer, wherein the upper surface of the first composite board layer is provided with a bottom connecting layer, the upper surface of the bottom connecting layer is provided with a second composite board layer, the upper surface of the second composite board layer is fixedly connected with a middle connecting layer, the upper surface of the middle connecting layer is provided with a third composite board layer, the upper surface of the third composite board layer is fixedly connected with a top connecting layer, the upper surface of the top connecting layer is fixedly connected with a fourth composite board layer, the bottom connecting layer comprises an inverted curve supporting layer and a bottom curve supporting layer, the bottom curve supporting layer and the bottom connecting layer are arranged in an staggered mode, the inner cavities of the bottom connecting layer and the top connecting layer are respectively provided with a filling layer, the first composite board layer and the fourth composite board layer are fixedly connected with a waterproof layer, the high-strength corrugated board layer is improved by the combination of the bottom curve supporting layer, the inverted curve supporting layer and the inverted curve supporting layer, the high-filled composite corrugated board is filled with the high-strength composite corrugated board, the high-strength composite corrugated board is improved, the high-strength corrugated board is filled between the two layers is filled with the corrugated board, and the high-strength composite corrugated board is filled with the high-strength composite corrugated board, and the high-strength corrugated board is filled with the supporting layers, simultaneously, the reinforcing net and the aluminum foil layer are matched to reinforce the paperboard layer, so that the paperboard layer is prevented from being torn, the stability of the high-strength composite corrugated paperboard is improved, and meanwhile, the waterproof layer is utilized to enable the high-strength composite corrugated paperboard to have a waterproof function.
