The origin of the adjective is uncertain; it is possibly from flim(-flam) (“(noun) false information presented as true, misinformation, nonsense; poor attempt at deception, confidence trick, pretence; (adjective) frivolous, nonsensical; deceptive; fictitious”) or a metathesis of film (“thin layer of a substance; slender thread”) + -sy (suffix forming adjectives and nouns). The noun and verb are derived from the noun. Noun sense 4 (“metal container”) refers to the fact that the containers often split along their seams and leaked.
