[0002] Packaging materials refer to materials used to manufacture packaging containers, packaging decoration, packaging printing, packaging transportation, etc. to meet product packaging requirements. They occupy an important position in the entire packaging industry and are the basis for developing packaging technology, improving packaging quality and reducing packaging costs.
[0003] Paperboard is one of the most widely used packaging materials. Existing paperboard packaging materials usually have a corrugated paper layer inside, which can improve the thickness and buffering and collision prevention capabilities of the paperboard. However, its anti-bending ability is insufficient. Although the cross section along the corrugated line of the paperboard can effectively improve the anti-bending ability, the anti-bending ability in the direction perpendicular to the cross section is seriously insufficient, making it impossible to be used for packaging high-load materials. Therefore, a heavy-duty paperboard packaging material for high load is proposed. Utility Model Content
