Offgassing of plastic containers.
I've heard forum members talking about offgassing of plastics and it's possible adverse effects on cigars. Then I started thinking about the plastics in my coolidors. The coolers themselves are food grade (I think) so I'm not too worried about the cooler itself. But I use some plastic tray/baskets for singles. The baskets are cheap and purchased at Dollar General Store and until I heard about offgassing I have never considered them anything but safe for cigar storage. They are Number 5 Plastics made of polypropylene which is also used as yogurt containers, syrup bottles, ketchup bottles, caps, straws and medicine bottles. So I feel like they're pretty safe. Is there any reason to think they're not safe for cigar storage?
