Technical Field
The invention belongs to the technical field of corrugated boards, and particularly relates to corrugated paper for packaging.
Background
Corrugated board is a multi-layer adhesive body, which is composed of at least one layer of wavy core paper interlayer (commonly called as "hole paper", "corrugated core paper", "corrugated paper core", "corrugated base paper") and one layer of paper board (also called as "box board paper" or "box paper board"). It has high mechanical strength and can resist collision and falling in the process of transportation. The actual performance of a corrugated box depends on three factors: the nature of the core paper and paperboard and the structure of the carton itself.
The corrugated corrugations of the corrugated board are like arch doors which are connected one by one, are mutually parallel to form a row and mutually support to form a triangular structure body, so that the corrugated board has better mechanical strength, can bear certain pressure from a plane, is rich in elasticity and has good buffering effect; the cushion can be made into liners or containers with various shapes and sizes according to requirements, and is simpler, more convenient and faster than plastic buffer materials; the coating is slightly influenced by temperature, has good light-shielding property, is not deteriorated by illumination, is generally slightly influenced by humidity, but is not suitable for long-term use in an environment with high humidity, and influences the strength of the coating.
The invention discloses a novel high-elasticity double-corrugated-core corrugated board which comprises outer-layer surface paper and inner-layer surface paper, wherein V-shaped corrugated core paper formed by combining three small V-shaped micro-ridges is arranged between the outer-layer surface paper and the inner-layer surface paper. The corrugated medium paper is made of corrugated base paper or kraft paper, and the surface paper material is boxboard paper. The number of layers of the corrugated medium paper can be a single layer or more than two layers; and sandwich paper can be added between the two layers of corrugated medium paper.
The existing corrugated board cannot be quickly recovered after being stressed and deformed, cannot timely protect objects again, and simultaneously, the use of the corrugated board is influenced because the compression strength and the bending strength of the paper core of the existing corrugated board are weaker.
