High-Efficiency Roller Coating Line for Pulp Molding with ≥90% Transfer Efficiency and ±2% Coating Accuracy

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.

Frequently Asked Questions

Q1: What is the typical production capacity of this roller coating line?

Production capacity ranges from 240-800+ pieces per hour depending on configuration (10-40 cycles/minute, product dependent). By adding stations or increasing conveyor speed, throughput can exceed 1,000 pieces per hour. Capacity is fully customizable based on your target production volume and product geometry.

Q2: What types of coatings are compatible with the roller coating process?

The line is compatible with water-based dispersions (PE, PLA, bio-based polymers), PFAS-free barrier coatings, oil-proof emulsions, and functional additives (anti-static, hydrophobic). For solvent-based coatings, we can upgrade the enclosure with explosion-proof electricals and enhanced exhaust—a customizable option.

Q3: How does roller coating compare to spray coating in terms of material waste and coverage uniformity?

Roller coating achieves transfer efficiency ≥90-95% (material applied vs. material used)—significantly higher than air spray (40-60%). The precision roller system spreads coating uniformly across internal surfaces, eliminating pinholes and streaks common in spray application. For high-value barrier coatings (e.g., bio-based polymers), roller coating can reduce material costs by 30-50%.
