You can judge the flexibility before you buy the tray. As to chemical reactions, I really didn't worry much about that as these are some fairly thick plastics. If they were going to react, the most I'd be out is one print if I didn't notice right away, plus a couple of bucks. So far, though, no problems at all with the cheapest things that WalMart sells.
