How plastic wrap works? It clings to things because of it's charge right? Well shouldn't it repel itself? Yet it doesn't.

    You are right about the charge, static charge that is. If the charges are evenly distributed across the surface then there will be enough positive and negative charges so that the material, in this case, plastic wrap will be attracted to itself. The static charge produces the "sticky nature" of plastic wrap.

    Plastic wrap, known as cling-film in the United Kingdom, is a thin polymer material, roughly 0.004" to 0.006" (0.11 to 0.15mm) thick, typically used for sealing food items in containers to keep them fresh. The wrap, typically sold on rolls in boxes with a cutting edge, clings to many smooth surfaces and can thus remain tight over the opening of a container with no adhesive or other devices.

    Static electricity, but a weak one. It is very sticky but not sticky like tape, that's static.
