Description
Technical Field
The utility model belongs to the technical field of packaged articles, and particularly relates to a corrugated reinforced paperboard and a carton made of the corrugated reinforced paperboard.
Background
The corrugated board is made up by using face paper, liner paper, middle paper and corrugated paper which are made into corrugated form through the processes of adhesion. According to the requirement of commodity package, the corrugated board can be processed into single-sided corrugated boards, double-layer corrugated boards, three-layer corrugated boards, five-layer corrugated boards, seven-layer corrugated boards, eleven-layer corrugated boards and the like.
The corrugated board is a multi-layer adhesive body, at least consists of a layer of wavy core paper interlayer (commonly known as 'hole paper', 'corrugated core paper', 'corrugated paper core', 'corrugated raw paper') and a layer of paper board (also known as 'box board paper', 'box paper board'), has higher mechanical strength, can resist collision and falling in the process of carrying, and the actual performance of the corrugated board depends on three factors: the characteristics of the corrugated paper and board and the structure of the carton itself.
In 1920 years, double corrugated cardboard came out, and its use was rapidly expanding. During world war i, corrugated containers account for only 20% of the shipping package. But during world war ii corrugated boxes have accounted for 80% of the shipping packaging. Corrugated containers are now the most widely used packaging containers in modern commerce and trade, and are one of the most important packaging forms adopted by countries in the world today.
By the end of the 19 th century, the united states began investigating the use of corrugated board for packaging and shipping containers. The corrugated paper board is made into a corrugated paper box through die cutting, indentation, box nailing or box 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.
Corrugated cartons generally comprise a rocking cover (also called a top cover and a box cover), a bottom cover (also called a box bottom), and a body plate (also called a peripheral wall and a vertical plate) surrounded by corrugated boards between the rocking cover and the bottom cover.
Since the packaging cartons are commonly used for transporting and protecting products, the quality of the packaging cartons is also strictly required. Carton detection items include: resistance to compression, edge compression, bond strength, puncture, simulated transport resistance to earthquakes, falls, and the like.
In order to increase the transportation efficiency, a plurality of layers of cartons are often stacked and stacked, which requires that the cartons have high compressive strength, and the strength of the carton body plates plays a crucial role in the compressive strength of the cartons.
The existing rocking cover, the bottom cover and the body plate are of the same thickness and structure, and when the compression strength of the body plate is increased only by considering the tile, the cost is increased due to the increase of the materials of the rocking cover and the bottom cover.
The ultra-strong double-body paperboard is developed from single-pit paperboards, one layer of corrugated paper in the middle of the ultra-strong double-body paperboard is formed by overlapping and bonding two pieces of thick corrugated paper, but the double-body paperboard is of the same and uniform structure on the same layer, namely the corrugated paper formed by overlapping and bonding two pieces of thick corrugated paper is integrally bonded with surface paper and lining paper, in reality, the integral design or the requirement of the integral design on the same strength index is not needed sometimes, such as the design of a carton, in order to meet the index of compressive strength, the strength of the vertical plate of the carton can only be enhanced, the design requirement can be met by increasing the thickness of the paperboard on the vertical plate in the compressive mode, if the thicknesses of the paperboards on the top cover and the bottom cover of the carton are increased simultaneously, the strength of the vertical plate of the carton does not contribute greatly, and paper materials are wasted.

Corrugated paper 52 and second lower corrugated paper 53 can be the single-deck corrugated paper of the same structure of body coupling in corrugated paper 51, second, promptly on the basis of corrugated paper board is strengthened to above-mentioned three-layer, has simply added paper and ordinary corrugated paper in the one deck, and then from the holistic increase in strength of cardboard. (it should be emphasized that the description herein of the single-layer corrugated paper of the same structure integrally connected to the second upper corrugated paper 51, the second middle corrugated paper 52 and the second lower corrugated paper 53 does not mean that the second upper corrugated paper 51, the second middle corrugated paper 52 and the second lower corrugated paper 53 are three parts which are split, and the description is only for convenience.)
Or: corrugated paper 52 is formed by two-layer corrugated paper laminating to bind in the second that is arranged in the middle of corrugated container board, corrugated paper 52 is equipped with one deck corrugated paper between 1 with first well paper 6 or in 2 with first well paper 6 between with the facial tissue of layer both sides in being arranged in the second, perhaps: the second middle corrugated paper 52 and the second lower corrugated paper 53 positioned in the middle of the corrugated paper board are formed by overlapping and bonding two layers of corrugated paper, and one layer of corrugated paper is bonded between the surface paper 1 and the first middle paper 6 or between the inner paper 2 and the first middle paper 6 positioned on the other side of the same layer of the second middle corrugated paper 52. This design is to increase the strength at the second middle corrugated paper 52 or the second middle corrugated paper 52 and the second lower corrugated paper 53, and to increase the strength at the body sheets and the bottom cover which are later formed into the carton.
The second middle corrugated paper 52 and the second lower corrugated paper 53 are formed by stacking and bonding two corrugated papers with the same or different corrugated shapes. For example: according to the design requirement, the middle corrugated paper 52 or the middle corrugated paper 52 and the lower corrugated paper 53 are formed by stacking and bonding two same A-type or C-type corrugated papers, or the middle corrugated paper 52 and the lower corrugated paper 53 are formed by stacking and bonding an A-type corrugated paper and a B-type corrugated paper. Of course, the bonding of two layers of corrugated paper of the middle corrugated paper 32 includes, but is not limited to, the same type a or the same type C, and the bonding of type a corrugated paper and type B corrugated paper.
