If SUPER GLUE stick's SO MUCH to ALL surfaces and to are hands and is SO DIFFICULT/IMPOSSIBLE to remove why does'nt it stick to the Inside of a plastic container that holds it?(i.e SUPER GLUE)

Super glue needs mosture to set up, and oxygen keeps it from setting up. The tubes are actually filled with oxygen to keep it liquid before use, that's why there is so little super glue in the actual tube. When you squeeze it out, the moisture in the air or the surface you put it on makes it react and set up. The reason it sticks to skin so well is that skin has lots of moisture in it.
Sounds backwards, but that's how cyano-acrylate (supe glue) works.

In order for the glue to dry, it has to be exposed to air so that the liquids in it will volatize. Because it is in a container kept away from air, it cannot solidify.

coz only the top layer is in contact with the air so it doesn't go off. It needs air to glue up things.

chemicals within the glue work when exposed to air

bcos the inside is made of an inert material
that precludes the necessary bonding reaction
simple.

the bottle and cap are made of PTFE a type of plastic that nothing sticks to. like teflon in your skillet.

because its air that makes it react and naturally all the time its sealed air cannot cause it to create a reaction

because its air tight leave the lid off and wait for a bit then it will dry up

It needs water vapor to set up ...
