PUL vs. TPU
When it comes to cloth diaper cover material, you probably have encountered the acronyms PUL and TPU frequently and used interchangeably. Are you wondering how they are different from each other?
PUL stands for Polyurethane Laminate and TPU is Thermoplastic Polyurethane Laminate. They are of the same waterproof Polyester based material. The only difference is their process of lamination. PUL is chemically bonded while TPU is bonded by heat. Function-wise, they work equally well.
The Cutie Patootie FlexiNappy covers, along with our Wetbags and Pail Liners, only use TPU; Which means, they are chemical-free. In our efforts to stay eco-friendly, this material is safer for the environment, and the babies too!
