I'm extremely sensitive to cheap saran wrap. It reeks and will ruin anything it touches in taste for me too.I have that with ants, specifically the really tiny kind. I am always battling ants at my house during the summer, they're a force of nature. I can smell them from a room away when they've swarmed something. It smells like acetone crossed with something else, like a really primal, evocative smell. When I smash even a single one it almost makes my eyes water. It's such a strong smell to me, but what's weird is that my girlfriend, my ex, and anyone else I've talked to about it can't smell them.
My partner can taste different metals, and its putrid to him. Coffee cup with a metal rim? Ruined.
