Dear Geri, I recently saw a safe, effective method of packing a photo exhibition that you might want to consider. The photos in the show I saw are prints mounted on aluminum panels with metal cleats verso for hanging. For packing each panel is attached to a handling frame. The handling frame is a simple framework of clear pine 1 x 4's consisting of two vertical bars at the sides and two horizontal cross bars. The horizontal bars are positioned so the cleats can be secured (screwed) to them. Each packing box contains a travel frame into which are packed four to six such handling frames. Each travel frame is wrapped in polyethylene. Your photos are a bit heavier than the aluminum panels. You might not want to pack more than four into a box. The travel frame rested on ethafome bumpers at the corners and around the perimeter and lid of the box. Alternatively, you could forgo the travel frame and stack the handling frames one atop the other in the box. You could instead wrap each handling frame in Velora, a very fine acetate-like material. The works travelled safely and were quickly unpacked and repacked. This is no doubt costlier than some variation of a soft-packed-and-crated solution but if your budget would allow it, and if you envision a tour of the photos, it may be worth considering it.
