Abstract

The invention relates to the technical field of wrapping paper, and discloses a six-layer corrugating paperboard, which comprises a first surface paper (1), a second surface paper (2), an inner paper(6), a core paper (4), a first corrugating paper (3) and a second corrugating paper (5), wherein the first surface paper (1) is arranged on the second surface paper (2), the first surface paper (1) and the second surface paper (2) form a double layer structure, the first corrugating paper (3) is arranged between the second surface paper (2) and the core paper (4), and the second corrugating paper(5) is arranged between the core paper (4) and the inner paper (6). The invention further discloses a production process of the six-layer corrugating paperboard. According to the present invention, the six-layer corrugating paperboard has the improved edgewise crush resistance and the improved bursting strength, and further has advantages of convenient processing molding, light weight, small thickness and high strength compared to the five-layer corrugating paperboard and the seven-layer corrugating paperboard.

Description

technical field [0001] The invention relates to the technical field of wrapping paper, in particular to a six-layer corrugated cardboard and a production process thereof. Background technique [0002] With the progress of society and the continuous development of economy, the pressure brought by packaging waste to the environment and the waste of materials and economy have become increasingly prominent. In view of factors such as economy and environmental protection, corrugated cardboard as a paper packaging material is more and more recognized and favored by merchants. Today, with the increasing popularity of corrugated cardboard, 75% of products in our country use corrugated cardboard boxes for transportation packaging. Corrugated cardboard uses corrugated corrugated as the cardboard core layer for multi-layer compounding, and can also be made into corrugated cardboard cushioning packaging liners. [0003] As a cushioning and protective packaging material, corrugated box...
