Description

Composite buffer material

Technical Field

The utility model relates to a packaging material technical field, more specifically the says so, relates to a composite cushioning material.

Background

With the rapid development of electronic commerce and express industry, the waste packaging paper box becomes an important component part in household garbage, most of the transportation packaging paper boxes take corrugated boards with light weight, low price and high bending strength as materials, the corrugated boards which are most widely applied at present are composed of surface paper, corrugated cores and inner paper, and the side surfaces of the corrugated cores are in V-shaped, U-shaped or UV-shaped corrugated shapes. Although waste paper has become one of the main raw materials for producing corrugated paper with the penetration of environmental protection and resource utilization ideas, so that the recycled fiber content in corrugated medium paper is generally higher than 30%, most of the medium paper pulp is raw wood pulp, which increases the demand for wood, and most of corrugated paper boxes are disposable, which results in substantially larger consumption ratio of natural resources and energy, and corrugated paper boards are not a green packaging material from the viewpoint of package life cycle evaluation.

To solve the problem of environmental protection, improvement is made on the defects of corrugated board materials, and it is reported that a corrugated medium paper is prepared by compounding a textile material and a natural polymer material: the straw is crushed, pulped and sprayed on the surface of the textile to form a straw layer, then the straw layer is pressed by a grooved roll to form a rack-shaped structure, core paper is formed, and then the core paper and surface paper are combined into a corrugated board, but the process is complex and the manufacturing cost is high.

SUMMERY OF THE UTILITY MODEL
