Are Polyurethane Diaper Covers Safe for Babies?
PUL is short for PolyUrethane Laminate, which is a fabric that has been heat-laminated to a layer of polyurethane. Diapers are usually made from laminated cottons, polyester knits, or poly blends.
Polyurethane is a pretty toxic plastic. You can read more about it at www.polyurethane.org. This is an industry-sponsored website. In particular, click on the link for "Hyperreactivity and Other Health Effects of Diisocyanates: Guidelines for Medical Personnel".
This plastic is more toxic than I would want to put next to a baby's tender skin.
