BOPP coating head

BOPP coating head

The BOPP Coating Head is a precision component used in coating and lamination machines for applying a uniform adhesive or functional coating onto BOPP (Biaxially Oriented Polypropylene) film. Designed for high-speed and consistent performance, the coating head ensures excellent coating accuracy, smooth surface finish, and controlled coating weight. It typically consists of an applicator roll, metering roll, and backup roll configured for methods such as gravure, reverse roll, or knife-over-roll coating. The gap between the rolls and coating pressure is finely adjustable to achieve the desired coating thickness, ensuring uniformity across the web width. The coating head is often made of hardened and chrome-plated steel or stainless steel to resist wear and chemical corrosion from adhesives or coatings. Servo-driven controls and precision bearings maintain stable operation even at high line speeds. The BOPP coating head is widely used in flexible packaging, label stock, and lamination applications where high clarity, bond strength, and surface uniformity are critical.
