I would say that zip and unzip can be understood as an equivalent to rar and unrar, tar and untar. I wouldn’t say that it necessarily needs anyone imagining a bag being zipped. But, it might as well be the fact that English isn’t my first language.
I think people mostly aren’t imagining it, though you do see the metaphor in icons and hear it in explanations.
