Isopropanol and plastic sheeting

A colleague who does not subscribe to this list is wondering if
anyone can provide some information. He has some large marine
specimens which need to be crated.

He would like to know which polymer sheeting (5-6 mil) will do the
best under conditions of total immersion in 60% isopropanol.
Polyethylene, polypropylene, or some other, including sandwiched
films.  What kind of longevity figures could he get before crazing
or embrittlement sets in?
