ABOUT EVA, from a Healthy Child Healthy World blog by Janelle Sorensen.
"Ethylene vinyl acetate (EVA) has been the safer substitute for
PVC for several years. According to Wikipedia, EVA is used as foam for
various types of padding, in hot glue sticks, in plastic wraps, some
artificial flowers, many Crocs-brand shoes and accessories, and more.
One of the reasons EVA is superior to PVC in regards to health and
environmental impacts is that it does not require the addition of
chlorine (which leads to the generation of dioxin, a highly persistent
carcinogen) and it doesn’t require plasticizers (like BPA or
phthalates). It is safe enough to be recommended by our esteemed
colleagues at Health Care Without Harm for use in neonatal intensive
care units, so you shouldn’t worry about your baby playing on it or
gumming it up a bit."
