Kohler Coating and BHS Corrugated target 15000 sheets per hour with new single-face laminator

In a move that pushes the mechanical limits of corrugated board production, Kohler Coating has formalized a strategic partnership with BHS Corrugated to engineer a high-speed single-face laminator capable of reaching 15,000 sheets per hour. Announced in July 2026, this joint development targets one of the most persistent bottlenecks in high-graphic packaging and specialty board manufacturing: maintaining absolute sheet flatness at extreme operational speeds.

Engineering the 15,000-Sheet Threshold

The collaboration merges two highly specialized engineering domains. Kohler Coating is integrating its proprietary closed-loop moisture control and thin-film glue application systems, while BHS Corrugated is providing the heavy-duty wet end architecture required to sustain continuous high-speed operation. Reaching 15,000 sheets per hour is not merely a matter of accelerating drive motors; it requires a fundamental stabilization of the web tension and adhesive application.

Historically, single-face lamination at speeds exceeding 10,000 sheets per hour introduces severe warp issues due to uneven moisture penetration and thermal variations. Kohler's rod-metered film applicator systems address this by drastically reducing the volume of water introduced into the board via the starch adhesive. By applying a highly precise, minimal film of glue, the system mitigates the warp effect before it begins.

Closed-Loop Moisture Control

The integration of closed-loop moisture control is the technical cornerstone of this new laminator. The system continuously monitors the moisture profile of the web in real-time, automatically adjusting the application parameters to compensate for variations in the raw paper rolls. This level of automation is critical in 2026, as converters increasingly rely on lighter basis weights and recycled fibers, which are notoriously sensitive to moisture fluctuations.

• Target Speed: 15,000 sheets per hour.
• Core Technology: Closed-loop moisture control and rod-metered adhesive application.
• Partnership Dynamics: Kohler Coating fluid management combined with BHS Corrugated wet end mechanics.

Sustainability Through Precision Engineering

Beyond raw speed, the environmental and operational efficiencies of this partnership are significant. Traditional laminators often over-apply starch to compensate for uneven paper profiles, leading to excessive energy consumption in the drying phase. Kohler's thin-film technology inherently reduces starch consumption, which in turn lowers the thermal energy required to cure the board. In the context of 2026's stringent energy regulations and corporate sustainability mandates, reducing the carbon footprint per square meter of corrugated board is a major competitive advantage. By minimizing warp and edge crush failures, the closed-loop system also drastically reduces physical waste, ensuring that more of the raw material ends up as sellable product rather than repulpable scrap.

Market Implications for High-Graphic Packaging

The demand for litho-laminated packaging continues to grow, driven by retail-ready packaging and premium e-commerce unboxing experiences. Brands require the structural integrity of corrugated board combined with the visual fidelity of offset printing. However, the lamination process has often forced converters to compromise between speed and quality. A machine capable of 15,000 sheets per hour effectively aligns the output of the laminator with the fastest modern offset presses, eliminating a traditional production bottleneck.

Furthermore, BHS Corrugated's involvement ensures that the new laminator will likely integrate seamlessly into broader digitalized plant architectures. As part of the industry's push toward highly automated facilities, the ability to capture real-time production data from the laminator's moisture and glue systems will allow plant managers to optimize starch consumption and reduce waste.

Combining Kohler's precision fluid management with BHS's heavy-duty wet end architecture is exactly the kind of pragmatic engineering the corrugated sector needs to push throughput limits. Will downstream converting and stacking systems be able to keep pace with a laminator ejecting 15,000 sheets every hour?
