Saran is still on the market.
Peter Meek has a lot of good info in his post.
I will just add that Saran is PVDC poly vinylidene Di Chloride.

That may explain why it clings so well when stretched a bit. If PVDC
is stretched enough that the polymer chains are more or less aligned,
it because piezoelectric; deformation creates an electrostatic
potential in the material. If the charge has nowhere to leak off,
it becomes the static electric equivalent of a permanent magnet.

I have noticed that meats double-wrapped in saran do NOT freezer burn
for as long as I'd want to keep frozen meat -- several months!
