What is peva?

Answer 1

According to the Healthy Building Network, PEVA is polyethylene vinyl acetate and is a plastic and a vinyl. In fact there are several types of vinyl - ethylene vinyl acetate (EVA), polyvinyl acetate (PVA) and polyvinyl butyral (PVB) on top of both PEVA and PVC. We already know that PVC stands for polyvinyl chloride and the Healthy Building Network further breaks down why PVC is so toxic. The C stands for chloride or chlorine and that is what is responsible for the harmful dioxins that PVC emits. So can we then assume that since there is no C in PEVA that it is non-toxic? The Healthy Building Network again: Absence of chlorine alone does not make these other vinyls the final answer in the search for green polymers. There are still plenty of toxic challenges and untested chemicals in the life cycle of any petrochemical product. As is the case with most other polymers competing with PVC, however, the weight of available evidence indicates that the absence of chlorine in the formula will generally render the lifecycle environmental health impacts of PVB and the other vinyls less harmful than PVC and initial study is bearing this out. And the Center for Health, Environmental and Justice points to a study on EVA, and other PVC alternatives (PDF), that states that “…EVA does not require phthalate additives to achieve flexibility…” Phthalates, as you’ll recall are the other culprits in PVC that leads to its toxicity. EVA has also been touted as an alternative to PVC for use in children’s toys including teething rings and PEVA has also found its way into sandwich wraps.

Answer 2

PEVA (polyethylene vinyl acetate) is a type of plastic commonly used as a lining for shower curtains, tablecloths, and other household items. It is considered more environmentally friendly compared to PVC due to its lower chlorine content.
