Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paperboards, in particular to an environmentally friendly composite corrugated paperboard. Background Art

[0002] Environmentally friendly composite corrugated cardboard is a new type of material with the advantages of saving resources, protecting the ecological environment, and low cost. The raw materials are widely available and can be recycled after use. It meets the environmental protection requirements of resource recycling and has extremely broad application prospects. Environmentally friendly composite corrugated cardboard is made of at least one layer of corrugated core paper interlayer and one or more layers of cardboard through bonding. It has high mechanical strength and good cushioning performance. The core paper is usually made of wood pulp paper or waste paper pulp paper, and the cardboard is made of wood fiber paper or recycled paper. Waterproofing agents, oil-proofing agents, etc. can be added to improve performance.

At the same time, the round paper strips and other cardboard structures are made of recycled waste paper, which has the effect of recycling and environmental protection. However, the moisture-proof effect of the environmentally friendly composite corrugated cardboard is poor. The current environmentally friendly composite corrugated cardboard has a simple structure and is usually made of paper. When used in a humid environment, it is very easy to be affected by moisture, resulting in the structure of the environmentally friendly composite corrugated cardboard becoming loose, causing the environmentally friendly composite corrugated cardboard to be damaged and unusable.
