<p>[QUOTE="desertgem, post: 1745503, member: 15199"]The URL list is somewhat dated. The food covering and cling wraps such as Saran and Ziplock products have not been produced with PVC ( chloride or plasticizers ) since approximately 2002. Most flexible food containers such as Peanut butter containers are now PET. Perhaps some from other manufacturers brands from other countries have problems, but I always specify Zip-Lock, even though many 99 cent store products in this line are Polyethylene or PET as well. I took time and checked the bottom of all of my plastic food containers, and even some old tupperware in the garage from at least the 1990s and non were PVC.</p><p> </p><p>PVC coin products have 2 problem points IMO. In newer PVC products, the amount of plasticizers are large and prone to gaseous migration and in the presence of moisture can produce corrosive ( acidic) action against coin metal. In older PVC, once the plasticizers have dissipated, the PVC itself is relatively inert. Many "survivalists" store caches of ammo and coins in sealed Rigid PVC tubing underground. The second problem is that when PVC reaches etreme temperatures such as in a house fire, they produce nasty residue.[/QUOTE]</p><p><br /></p>
