I will occasionally receive electronic components from China tightly wrapped in this plastic film. It's much thicker than general plastic wrap that's bought from the store and does a good job at adhering to itself when wrapped.
I have tried wrapping the same parts using generic plastic wrap for food but it fails to adhere; providing a loose wrapping that will unspool itself.
Is this material something used in packaging? Does it have a name?
Is this possibly some kind of wrappable heat shrink?
