I don't think it's secretion but rather the different type of plastic which
seems to latch on to whatever is in the air. My very first experience with
the stickiness was with an old 'cake taker', an item that had a rubbery feel
to it, similar to that of the seals. That's how I discovered the baking
soda trick. The sticky film came right off the cake taker and left it
almost as good as new.
