PUL, or polyurethane laminate, is a type of fabric that is coated with a layer of polyurethane. This coating makes the fabric waterproof and breathable, making it ideal for various applications, including outdoor gear, medical supplies, and baby products. PUL is often used in items like diapers, rain jackets, and sleeping bags due to its durability and resistance to wear. The manufacturing process of PUL involves bonding a polyurethane film to a base fabric, which can be made from materials like cotton or polyester. This combination provides both flexibility and strength, allowing PUL to maintain its shape and functionality over time. Its versatility and effectiveness have made it a popular choice in many industries.
