Introduction
PVA water-soluble film coating production equipment is an automated system designed for manufacturing polyvinyl alcohol (PVA) films. It consists of key modules including solution preparation, precision coating, drying, peeling/winding, and slitting. The core process involves uniformly coating PVA solution onto a release substrate via blade, micro-gravure, or slot-die methods, followed by hot-air or infrared drying to form films with controlled thickness (typically 10-100μm). Equipped with PLC automation, the system precisely adjusts coating speed (5-50 m/min), temperature (50-120°C), and thickness uniformity (±2μm tolerance), while ensuring energy efficiency and low environmental impact. The resulting films are widely used in eco-friendly packaging (e.g., detergent pods, soluble agrochemical bags), medical applications (biodegradable dressings, oral dissolvable drug films), and industrial processes (water transfer printing, embroidery backing). Their complete water solubility and non-toxic degradation make them a sustainable alternative to conventional plastics.
