That's the headline Frank von Haste gave his very interesting blog post that provides a nice counterweight to some of the anti-plastics hysteria pervading much of the mainstream media. Brief summary: museum conservators are faced with problems as the PVC film used in the 1950s to protect some 1200-year old paper documents is now degrading. Paper lasting 11 centuries is in danger because the plastic applied to it five decades ago is degrading. That's certainly a healthy dash of irony.
