What makes clingfilm cling?

Answer by  KWags1977 (427)

Static electricity enables the cling film to cling to ordinary things. When you pull it apart, your creating static electricity between the film and the paper. Electrical conductivity is what the film is based on.

When you pull clingfilm from the roll, the sheet becomes charged with static electricity. Because the film is very thin and light, the static enables it to stick to itself and to other objects.

Clingfilm clings because of the phenomenon of static electricity. The ability to cling will be a function of many factors. Electrical conductivity of the materials in contact will be one of the more important factors. Additionally, the relative humidity of the environment will also play a part in the ability of the film to "cling".

Clingfilm cling because it creates static electricity which allows it to cling to its self and onto objects, its also because of its thin and flexible design whereas its surface clings no matter how much time it has been used.

Simply it is static charge that will attract objects of opposite charges. That is why it does so good with glass but not so well with plastics.

As the plastic is rolled onto the tube during production, it gives it a slight negative charge, so that when it is removed it clings better to smooth surfaces.
