Description

Corrugated paper board

Technical Field

The application relates to the field of paperboard technology, in particular to a corrugated paperboard.

Background

Corrugated containers are spliced into corrugated cases as containers for carrying objects, and the corrugated cases are often used in transportation due to the characteristic of convenient storage, and are required to face the adverse conditions of humidity, jolt and the like which easily damage the corrugated containers.

Chinese patent No. CN208290662U discloses a moisture-proof corrugated board, which comprises a surface paper, a wave-shaped core paper and a lining paper, wherein a resin film or a wax film is arranged on the outer surface of the surface paper, and a water-absorbent resin is arranged in the wave crest or the wave trough of the wave-shaped core paper. The utility model discloses an add one deck resin film or wax film on the surface course, its main moisture resistance, be provided with water-absorbing resin in the crest of wave core paper or the trough simultaneously, when the surface course waterproof ability is not enough, water-absorbing resin also can in time remedy, water-absorbing resin water absorption expansion, and water-absorbing resin after the water absorption expansion just can fill the buffer space that forms at wave core paper and facial tissue or interior paper, improve dampproofing corrugated container board's intensity, thereby can prevent breaking or collapsing of packing material more effectively.

In view of the above-mentioned related art, the inventors considered that the resin film or wax film of the outer surface layer of the face paper made the outer surface layer too smooth and the anti-slip property was weak.

SUMMERY OF THE UTILITY MODEL

Optionally, a triangular corrugated paper grid layer is vertically arranged on the outer side of the glass fiber net layer, the triangular corrugated paper grid layer is provided with a triangular prism cavity, and the triangular prism cavity is filled with the buffer rubber strips.

By adopting the technical scheme, the triangle is a stable structure, so that the triangular corrugated paper grid layer also has good pressure resistance, and the corrugated board has high strength. The rubber material has the effect of shock attenuation buffering, and the cushion rubber strip of packing in the triangular prism cavity can reduce the impact force that corrugated container board rest received when corrugated container board received the impact.

Optionally, the side edges of the corrugated board body are provided with sealing edges.

Through above-mentioned technical scheme, the side of ordinary corrugated paper is often in naked state, and interference factors such as moisture and spot easily get into corrugated container board inside from the side to make corrugated container board receive the damage, consequently set up the banding that is used for protecting corrugated container board inner structure.

In summary, the present application includes at least one of the following beneficial technical effects:

1. the yarn net is arranged on the surface of the corrugated board body, so that the surface of the corrugated board is uneven, the roughness is increased, and the anti-skid performance of the corrugated board is improved;
