Christy,
Are your Odonate envelopes polyethylene like Ainsley’s or possibly acetate (more probable to have static issues)??

Ainsley - do you experience any static damage of the Lep wings? We have about 6000 Leps in Odonate envelopes and I'm noticing some of the smaller specimens are suffering from the static. Wondering if anyone else is having this issue and found a solution.

Christy,
I checked an old BioQuip catalog. They are 1.25 mil ultra-clear non-static polypropylene. So probably not the problem. You might want to consult a museum conservator, especially with some chemical background. Unfortunately, not enough museum realize the value of having conservators on staff.

Dave -
