In the article entitled “Can a piece of paper be folded in half no more than seven times?”:

Cecil, with the help of Ms. Adams, tests that old challenge.
Unfortunately, instead of using paper (preferably an 8 1/2 x11 sheet), he uses metres of ultra-thin plastic.
Hardly the same thing.
When I tested the limits of that challenge as a child, I used single ply toilet paper, or seperated the sheets in paper towel, using a singly ply of that.
It was usually possible to fold at least 8 times.
Given that he changed the constraints of the problem (which essentially is to fold 128 sheets of paper stacked together in half), I don’t think that counts as a fair answer.
And he didn’t even mention that interesting quality of the challenge. Namely: locate a flexible material of a certain thickness which cannot be folded, then divide by factors of two until you find a deceptively thin thickness that you can use to demonstrate the power of exponentiation.
