<p>[QUOTE=&quot;mackwork, post: 1413398, member: 35676&quot;]PVC no longer in Saran Wrap, if that&#039;s the actual brand being questioned.

SC Johnson claimed that this change was a result of an initiative to look for more sustainable and environmentally acceptable plastic. The film in Saran Premium Wrap does not contain chlorine. However, LDPE does not possess the same barrier qualities to oxygen, aroma, and flavor molecules that vinylidene chloride copolymers do, making the new formulation a lower quality plastic wrap, as it is not as useful in protecting from spoilage or flavour loss.</font>[SUP][[/SUP]</span>[SUP]<i><a href="http://en.wikipedia.org/wiki/Wikipedia:Citation_needed" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://en.wikipedia.org/wiki/Wikipedia:Citation_needed" rel="nofollow"><span style="color: #0000cd">citation needed</span></a></i>[/SUP]<span style="color: #0000cd">[SUP]][/SUP]<font face="sans-serif"> PVC is not impermeable, but adheres well.
