I may be a bit weird. I found a thing in my house that said "please recycle" but didn't have the number to indicate what sort of plastic it was and it kinda just threw me off on this giant tangent of going through my house finding out what all the (labeled) plastics are. Turns out, it's almost exclusively PET, HDPE, and polypropylene. Foods aren't in HDPE, but, otherwise, it seems to be fair game on what it's made of. So, yeah. Fun tidbit of the day.
