ELI5: Why does packaging tape adhere so well to cardboard but terribly to almost everything else?
gpt
Because it's developed specifically to bond well with the fibers of the cardboard. If you try to stick another type of tape, say duct tape to a cardboard box it wont stick very well because it doesn't entangle the box fibers very well. Because packaging tape essentially relies on those fibers to form a good bond, it doesn't bond well to surfaces that can't provide something similar to the fibers.
