Roll-to-roll coating is a versatile, high-throughput manufacturing process used to apply precise coatings on flexible substrates such as films, foils, and papers. With techniques like slot-die, knife-over-roll, and air-knife coating, it enables uniform, scalable, and efficient production across industries including electronics, packaging, and pharmaceuticals. Integration with vacuum deposition and advanced process controls further enhances coating quality and material efficiency, making R2R coating a cornerstone of modern flexible device fabrication and surface finishing.
