Is kitchen wrap adhesive because of Electric Charge?

AI Thread Summary
Kitchen wrap, often referred to as cling film, adheres to surfaces due to electrostatic charges. The discussion clarifies that the stickiness is not related to metallic foil but rather to the properties of the plastic film itself. Participants emphasize the importance of terminology, distinguishing between foil and film. The adhesive quality is attributed to the film's interaction with positively charged materials. Overall, the conversation highlights the scientific basis behind the clinginess of kitchen wrap.

Hello,

I just came across this question and no answer could be find, my best assumption is that kitchen foil is simply 'holding' into positveley charged materials?

Thanks,
JJ

Thanks, I was right :cool:
 
N.B. It's not "foil". Foil is the terms for thin metal (a conductor). It's Film, we're discussing.

it's all clingon to me :biggrin:
 
It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
