Abstract
A cardboard-plastic slide mount includes a cardboard bottom, a cardboard cover and a plastic brace between the bottom and the cover. The cardboard bottom and the cardboard cover include aligned film windows. The cover and bottom have a plastic coating on their inner surface, allowing the plastic brace to be bonded to the cover and base using a bonding agent. When assembled, the plastic brace is located between the bottom and the cover to define a film nest for containing a film transparency.
