Abstract

The invention provides a corrugated paper box with high compressive strength and a preparation process thereof. The corrugated paper box comprises a box body composed of corrugated paper boards, wherein the corrugated paper boards comprise an upper paper board and a lower paper board; a first partition plate and a second partition plate are arranged between the upper paper board and the lower paper board; a plurality of closely-arranged paper tubes are vertically arranged between the first partition plate and the second partition plate; first corrugated paper and a first pressure-resistant tube which are arranged in a staggered mode are arranged between the first partition plate and the upper paper board; second corrugated paper and a second pressure-resistant tube which are arranged in astaggered mode are arranged between the second partition board and the lower paper board; the first corrugated paper and the second corrugated paper are both of semi-circular arc structures; and hemispherical hollow buffer cavities are respectively formed between the first corrugated paper and the first partition board and between the second corrugated paper and the second partition board. According to the corrugated paper box with high compressive strength, compared with the prior art, the pressure-resistant structures are arranged inside the corrugated paper boards, so that the corrugated paper box has high-strength pressure-resistant capability.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a corrugated box with high compressive strength and a preparation process thereof. Background technique [0002] Corrugated boxes have the advantages of light weight, good structural performance, puncture resistance, shockproof, cushioning, foldable, strong printing adaptability, easy specification change, environmental protection, recyclable and suitable for automatic packaging operations. In the fierce competition with other packaging materials, With its unique properties, corrugated cartons have become the most commonly used and rapidly developing paper packaging containers so far, and the most important form of packaging in modern packaging. [0003] At present, the corrugated boxes on the market are generally made of corrugated paper, and in order to make the corrugated boxes more beautiful and reduce the packaging cost of the products, enterprises gradually adop...
