Description

Technical Field

[0001] The utility model relates to the field of packaging cartons, in particular to a packaging carton board structure. Background Art

They are divided into single-corrugated (3-layer), double-corrugated (5-layer), triple-corrugated (7-layer), and quadruple-corrugated (9-layer) cartons. Cartons are further divided into paper boxes, color boxes, color boxes, and oversized odd-shaped beer boxes. Paperboard, also known as board paper, is a thick paper sheet made of various pulps and interwoven fibers. The difference between paperboard and paper is usually distinguished by quantity and thickness;

[0003] The existing packaging carton board structure has poor bending resistance, which leads to the box door being easily subjected to stress and bending during production, transportation and use, especially when folded into a box body but without items placed in it, thus affecting the overall quality and overall aesthetics of the carton (the square box structure is bent into an irregular shape), reducing the quality of the carton and making it less practical.
