ABSTRACT:
A shipping, storage tray for protecting the surface integrity of a sensitive brittle plate, such as glass, placed therein. The sensitive plate is cushioned along its lower peripheral edge on ridge and groove shaped side walls of a ductile, conformable support tray which prevent surface contact of the plate and the tray bottom. The edges of the tray are folded back and beneath the tray exterior to prevent flakes from the raw sheared edges from being deposited inside the tray and on the plate surface. A chemical coating to enhance wetability of subsequent photo-sensitive coatings on the plate surface is deposited in the tray bottom.
