Customizable Modular Roller Coating Production Line for Pulp Molding with High Material Efficiency and Precision Coating

This roller coating production line is engineered for applying uniform, high-performance internal barrier coatings—waterproof, oil-proof, and heat-resistant—to molded pulp tableware and packaging products. The precision roller coating process uses a dosing roller and applicator roller system with independently adjustable speeds to evenly spread coating over internal surfaces, eliminating pinholes and ensuring consistent dry film thickness.

Unlike spray coating methods, roller coating delivers transfer efficiency of ≥90-95%, drastically reducing material waste—critical for high-value barrier materials such as bio-based polymers and PFAS-free formulations. The closed-loop roller system minimizes volatile emissions, coating contamination, and workplace mess.

With intelligent PLC control and recipe-driven operation, the equipment supports fully customizable drying profiles, roller speed programs, and product fixture designs to accommodate different product geometries, coating formulations, and production throughputs.

Note: All technical parameters are customizable to meet specific production requirements and product specifications.
