They were regarded as the only type of regular affordable capacitor available from Philips, in a time when every manufacturer of such capacitors used impregnated paper in some kind of encapsulation. They all claimed to be moisture proof to some degree.

I don't know whether Philips really advertised them. I do know Wima and ERO did in the 1950's and 1960's, claiming new technology, new tropicalisations, etc. Spoiler: theirs turned out to be way worse after years of use than the Philips ones - but chances were if you used a radio or TV set for 20 years, some of the repairs done in that period would have involved replacing a paper capacitor, regardless of the manufacturer.
