Why is cling film so sticky when it touches itself or around bowls but it does not feel sticky at all when it touches our hands?
In: Physics
Cling film uses glue that is non-reactive with fats. That’s why if you get oil or fat on a bowl, it’ll no longer stick until you wipe it.
The static charge idea is an old-wives-tale most likely from getting confused with “static cling,” which is in fact due to static charge. Also, of course, it can be charged like any polymer, and it can cling to you when you do.
But the actual stickiness comes from glue; which is why a formulation change made it stick less, and it doesn’t stick to itself when cold. Both are characteristics of chemical bonding.
