I will be packing a large photograph on Aluminum for travel. There has been some chatter about not using Glassine as a first layer below bubble and cardboard when soft packing, is there any new information on this and is virgin poly the best alternative? Does anyone have experience with aluminum mounted photos?

Admittedly the best method for packing and travel would be a slat crate but the budget is not there for this.

Thanks for any insight.
