Description

High-strength light corrugated paper packaging structure Technical Field The utility model belongs to the technical field of corrugated paper packaging, and particularly relates to a high-strength lightweight corrugated paper packaging structure. Background Corrugated board is used as a common packaging material, and is widely applied to packaging of various products due to the advantages of light weight, low cost, recoverability and the like. In recent years, with the rapid development of electronic commerce and logistics industry, the strength requirements on packaging materials are higher and higher, and meanwhile, the packaging materials are required to be kept lightweight so as to reduce the transportation cost. The prior patent (publication number: CN 110606258B) discloses a corrugated paper packaging box, which comprises a fruit box and an end cover, wherein a plurality of fruit seats are arranged in the fruit box, the cross section of each fruit seat is in a cup shape with a wide upper end and a narrow lower end, the fruit seats are arranged in rows and columns, at least three fruit seats are arranged in each row, the distance between the central axes of adjacent fruit seats in each row is 20CM, at least two fruit seats are arranged in each column, the distance between the central axes of the fruit seats in each column is 20CM, the end cover is covered at the top end of the fruit box, and the inside of the end cover is buckled at the top end of the fruit box. Currently, corrugated boards commonly used in the market mainly increase strength by increasing the number of layers of the board or using high-gram-weight base paper, or add reinforcing materials such as plastic films or metal foils to the corrugated board to improve the bursting strength and tear resistance of the corrugated board, however, the multi-layer superposition can cause significant increase in weight, high-gram-weight base paper has higher cost and affects environmental protection and recyclability, so a high-strength lightweight corrugated paper packaging structure is proposed to solve the problems. Disclosure of utility model Aiming at the defects of the prior art, the application provides a high-strength light-weight corrugated paper packaging structure, which has the advantages of better integral damage-resistant effect of a corrugated paper board main body, smaller weight increase, longer service life and the like, and solves the problems that the weight is obviously increased, the cost of high-gram-weight base paper is higher, and the environmental protection property and the recoverability are influenced due to the fact that a plurality of layers of overlapping are pointed out in the comparison document.
