If you are not seeing any condensation then you are good. It is a good use for the tubs. I have used a similar materials for microclimates for archaeological metals and found them to be very tight maintain a low RH for up to 5 years. (off subject - sorry).

This is a message from the Museumpests List. To post to this list send it as an email to pestlist@museumpests.net<mailto:pestlist@museumpests.net> To unsubscribe please look at the footer of this email. ----------------------------------------------------------- Hi all, We have been fumigating herbarium specimens by first stacking the specimens in a plastic tub (usually Walmart specials), closing the tub with its somewhat secure lid, then putting the filled tub in a heavy gauge plastic bag which is tightly closed and then the entire unit is placed into the ultracold. We allow the 24 hour thaw and have not had any problems with internal condensation. I like using the tubs because they provide rigid support and protection and they make it easier to handle, stack, and transport specimens. Here is the part I am not so sure about. After thawing, the tubs are moved into the pest-free herbarium and some specimens remain in the tubs for several weeks before processing (we are a regional university and depend on part-time student helpers). My question...are the closed tubs providing pest protection to the specimens?
