You've just found a problem many industrial researchers
have been trying to solve for a long time. A very short
answer to your question is: there are no wonder glues
(or adhesives, as those familiar with the art prefer to
call them) that would bond any pair of materials.
Many popular plastics/polymers (such as polyethylene,
polypropylene, Teflon(tm)) just don't have any
functional groups that would react with a glue to form
a chemical bond. Their surface must be activated,
physically roughened, or, what's most effective, two
parts are just melted/sintered to form a joint.
