Degradable buffer material

Abstract

The invention discloses a degradable buffer material. The degradable buffer material is composed of a core material and a surface material, the core material is in the shape of a two-way superimposedcorrugation, the corrugation included angle of the two directions of the two-way superimposed corrugation core material is 1-90 degrees, and the corrugation cross sections in the two directions are inthe shape of a function curve or a combination of partial function curves. According to the invention, a high polymer material is molded into a bidirectional corrugated structure through a mold, is used as a core material to directly replace a corrugated board core paper material, and then is combined with a surface material to form the degradable buffer material with the corrugated structure, sothat the consumption of paper pulp is reduced, the manufacturing process steps are reduced, the recycling rate can be increased, and the problem that the performance of the corrugated board is reduced due to cyclic utilization is reduced.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, in particular to a degradable cushioning material. Background technique [0002] With the rapid development of electronic commerce and the express delivery industry, packaging waste cartons have become an important part of domestic waste, and most of the transport packaging cartons are made of corrugated cardboard with light weight, low price and high bending strength. The most widely used corrugated cardboard is composed of surface paper, corrugated core and inner paper. The side of the corrugated core is V-shaped, U-shaped or UV-shaped corrugated. Although with the deepening awareness of environmental protection and resource utilization, and the penetration of green packaging concepts, waste paper has become one of the main raw materials for the production of corrugated paper, making the proportion of recycled fibers in corrugated medium paper generally higher than 30%, but most cor...

Problems solved by technology

Although with the deepening awareness of environmental protection and resource utilization, and the penetration of green packaging concepts, waste paper has become one of the main raw materials for the production of corrugated paper, making the proportion of recycled fibers in corrugated medium paper generally higher than 30%, but most core paper Pulp is still log pulp, which increases the demand for wood, and most of the corrugated boxes are disposable, resulting in substantial consumption of natural resources and energy. From the perspective of packaging life cycle assessment, Corrugated cardboard is not a green packaging material

[0003] To solve the problem of environmental protection, it is necessary to improve the defects of corrugated cardboard materials. It has been reported that a kind of composite of textile materials and natural polymer materials is used to prepare corrugated medium paper: the straw is crushed and pulped and sprayed on the surface of the textile to form a straw layer. Finally, the straw layer is pressed with a grooved roller to make it have a rack-like structure to form a core paper, which is then combined with the face paper to form a corrugated cardboard, but the process is more complicated and the manufacturing cost is higher
