In the 2000s, Saran changed their formula to be less sticky: more convenient for most people, but also less useful to those adept in the mystic arts of cling-wrapping things. And where Saran goes, the clingwrap industry follows.
The switch was for a good reason, though: the stickiness was due to using PVDC, a chloride-containing polymer that's bad for the environment and in all likelihood not something you want near hot food. Delicious!
