The last batch of sheet film I bought was packaged in black plastic bags inside cardboard envelopes, which aren't so convenient to handle inside a dark bag. I'm looking for two or three empty 3-part film or paper boxes, 5x7 size (half-plate really, but it'll go in a 5x7 box), big enough for 25 sheets or so.
I'll pay postage to Switzerland, and a $2.50 donation to APUG for each box.
I can help you out, and would welcome the chance to support APUG as you suggest, but I am in California. Are you certain you are unable to find a source closer to you? PM me or contact via my site if all else fails.
P.S. - Freestyle often has film and paper boxes at their Hollywood location. I would advise contacting them to see if they can set you up.
