I've never seen any cautions about Bentonite and plastic...my guess is that it would be fine unless you are super sensitive like those who react to water in plastic bottles. Obviously glass is a better choice.

BTW Mark, I recall that you posted a while back about finding undisolved HH Intestinal Cleansing tabs in your stool...did I post a reply to you about this? If I didn't I meant to...those tablets have no coating on them and should break down pretty easily in the digestive system. The fact that this did not occur for you is a pretty good indication that you could use some enzyme support...digestive enzymes and possibly HCL. It's fine to chew/smash the tabs before using them...my concern here is more about how you're breaking down everything...not just the tabs. The directions for taking the tabs say to make sure they are on the back of the tongue prior to swallowing them...I have no idea why they suggest this...unless it has something to do with tasting the herbs and targeting particular taste receptors on the tongue...will try to find out more. If you know the reason for this, please fill me in...thanks.
