Buyers must distinguish between these materials based on application. PU (Polyurethane) film is generally softer, more breathable, and eco-friendly, making it ideal for apparel and medical use. PVC (Polyvinyl Chloride) film is more cost-effective, durable, and resistant to chemicals and weathering, which suits industrial covers, stationery, and upholstery. Always verify the thickness (measured in mm or microns) and hand-feel (hardness/softness) to ensure it meets your specific production requirements.
