Packaging Adhesives & Corrugating Technology

This technology is built on three core innovations: a matched instant-bond, instant-dry starch adhesive; room/low-temperature boiler-free corrugated board (carton) production line technology; and room/low-temperature boiler-free flute-to-flute corrugated board (carton) production line technology. Building on its boiler-free line technology, Xuegong Group has introduced a major new corrugated board production technology — boiler-free flute-to-flute, peak-to-peak corrugated board technology — for which it holds a patent. This flute-to-flute production line can manufacture both five-ply board with a core layer and four-ply board without a core layer.

Four-ply board without a core layer: constructed as facing paper + corrugating medium + corrugating medium + liner, with no core layer in between. Its physical structure forms a diamond-to-triangle pattern, which is more structurally sound. This design significantly improves both flat crush and edge crush strength while resolving the long-standing warping problem in corrugated board, and can replace traditional five- or seven-ply board. Compared with traditional five-ply structures, it saves the core paper layer while matching or exceeding five-ply performance. Strength gains vary with corrugating paper quality, and production costs are reduced by more than 10%.

Five-ply board with a core layer:constructed as facing paper + corrugating medium + core paper + corrugating medium + liner. The five-ply structure forms a triangle-to-triangle pattern. Although it does not save on core paper, the triangular geometry provides excellent stability, delivering superior flat crush and edge crush strength, a significant overall strength increase, and the ability to reduce overall paper weight — cutting production costs by roughly 10% while offering stronger overall performance.

This combination of three integrated technologies substantially increases the technical sophistication and competitiveness of the production line while effectively lowering corrugated board production costs, delivering significant economic benefits to customers. After years of continuous R&D refinement — validated through lab trials, small-batch tests, and pilot production — the technology has matured into a genuinely new era for corrugated board manufacturing.

Compared with traditional high-temperature boiler lines and conventional corrugated board technology, this technology offers substantial competitive advantages in a large, stable market. Its widespread adoption benefits not only major carton manufacturers but also gives early-mover advantage to new investors and entrepreneurs entering the industry.
