What is PUL Polyester?

PUL (Polyurethane Laminate) Polyester is a special type of fabric that combines the strength and smooth texture of polyester with a thin, flexible waterproof layer made from polyurethane. This laminated fabric is soft, lightweight, and breathable, yet incredibly durable and water-resistant—making it ideal for a wide range of applications, from reusable products to medical and hygiene items.

How is PUL Made?

PUL fabric is created by bonding a polyester knit fabric to a layer of polyurethane film. This is typically done using a heat and pressure process, which fuses the materials together without the need for adhesives. The result is a fabric that maintains the comfort and stretch of polyester, while gaining the waterproof qualities of polyurethane. It’s strong enough to withstand repeated washing and sterilization, making it a favorite for long-lasting, sustainable products.

Why Choose PUL?

One of the biggest advantages of PUL Polyester is its versatility. It’s commonly used in cloth diapers, changing pads, mattress covers, wet bags, food wraps, and even medical garments—anything that requires waterproof protection without sacrificing comfort. It’s also an eco-conscious choice for those looking to reduce single-use plastic waste by creating reusable alternatives. Many PUL fabrics are CPSIA-compliant and free from harmful chemicals like BPA, lead, and phthalates, making them safe for babies and sensitive skin.
