Problems solved by technology
[0005] Corrugated cardboard is mainly composed of surface paper, core paper, corrugated paper and inner paper alternately bonded and fixed. The existing corrugated cardboard has a simple structure and a very single function, and some corrugated cardboards have low structural strength, poor wear resistance, and are prone to breakouts. Tear phenomenon, resulting in damage to the packing box
In order to strengthen the strength of cardboard, the usual method is to increase the number of layers of paper and the weight of paper, but this method not only consumes materials, but also increases the weight of cardboard, resulting in waste of resources

The invention relates to a paperboard, in particular to a reinforced corrugated paperboard. The reinforced corrugated paperboard comprises a paperboard body, wherein the paperboard body comprises surface paper, corrugated paper, core paper and inner paper, wherein reinforcing lines are uniformly laid between the surface paper and the corrugated paper; a reinforcing film made of PVC is pasted on the core paper; the corrugated paper comprises wave crest sections and wave trough sections, wherein an upper reinforcing block is arranged between every two wave crest sections, a lower reinforcing block is arranged between every two wave trough sections; the upper reinforcing blocks and the lower reinforcing blocks are made of a flexible material; and a wear-resisting layer is arranged on the outer surface of the surface paper. According the reinforced corrugated paperboard, the reinforcing lines and the reinforcing films are arranged in the paper board, so that the paper board is integrally firm and durable in use; the wave crest sections and the wave trough sections of the corrugated paper are equipped with reinforcing blocks, so that the paperboard can be effectively prevented from being sunken while hit, and therefore, anti-impact strength of the paperboard is improved, wear resistance of the paperboard is good and the service life of the paperboard is prolonged. The reinforced corrugated paperboard is simple in integral structure, is easy to manufacture, and is suitable for industrial production.
Description
[0001] (1) Technical field [0002] The invention relates to a cardboard, in particular to a reinforced corrugated cardboard. [0003] (2) Background technology [0004] Cardboard, also known as cardboard, refers to a thick paper sheet made of various pulps and interwoven fibers. The commonly used cardboard is corrugated cardboard. Corrugated cardboard is a multi-layer adhesive body. It consists of at least one layer of corrugated core paper interlayer and one layer of cardboard. It is mainly used to make cartons, the sandwich of cartons and the outer packaging of fragile goods. . Corrugated cardboard is less affected by temperature, has good shading performance, and is generally less affected by humidity. [0005] Corrugated cardboard is mainly composed of surface paper, core paper, corrugated paper and inner paper alternately bonded and fixed. The existing corrugated cardboard has a simple structure and a very single function, and some corrugated cardboards have low structu...
