Embodiment Construction

[0034] The following is attached figure 1 The application is described in further detail.

[0035] On the one hand, the embodiment of the present application discloses a corrugated cardboard, referring to figure 1 , including a panel 1, a corrugated core board 8 and a corrugated waterproof membrane 9; the panel 1 includes an outer waterproof board 2 with waterproof performance and an inner moisture-proof board 3 with a drying function, and the corrugated waterproof membrane 9 is arranged on the outer waterproof board 2 and the inner moisture-proof board 3 with a drying function. Between the corrugated core boards 8; the wave frequency of the corrugated core board 8 and the corrugated waterproof membrane 9 is the same, the wave amplitude of the corrugated waterproof membrane 9 is smaller than that of the corrugated core board 8, and the amplitude of the corrugated waterproof membrane 9 is the amplitude of the corrugated core board 8 1 / 4 to 1 / 5 of that, while the corrugated wat...

Abstract

The invention discloses a corrugated board and a processing technology thereof, and relates to the field of corrugated board packaging technologies, the corrugated board comprises a panel and a corrugated core board, the corrugated board further comprises a wavy corrugated waterproof film, the corrugated waterproof film is arranged between the panel and the corrugated core board, the corrugated core board and the corrugated waterproof film have the same wave frequency, and the corrugated waterproof film is arranged between the panel and the corrugated core board. And the wave amplitude of the corrugated waterproof film is smaller than that of the corrugated core board. The corrugated board has the advantages of being good in waterproof performance and more reliable in waterproof effect.

Description

technical field [0001] The present application relates to the field of corrugated cardboard packaging technology, in particular to a corrugated cardboard and its processing technology. Background technique [0002] Corrugated cardboard is a multi-layer bonded body. It is composed of at least one layer of corrugated core paper interlayer and one layer of cardboard. It has high mechanical strength and can withstand collisions and falls during handling. The actual performance of corrugated cardboard Depends on three factors: the properties of the medium and paperboard and the structure of the carton itself. [0003] In related technologies, corrugated cardboard is often used to make corrugated cardboard boxes for packaging and transporting products. However, corrugated cardboard has poor waterproof performance. When it is wet or exposed to water, it will quickly absorb water and become squishy, ​​which affects the normal use of corrugated cardboard. The moisture-proof measures...
