ABSTRACT:
An envelope construction for high speed printing includes a front panel having a flap with a sealing adhesive strip on its back side, and a rear panel secured to the front panel at its marginal edges to form a pocket. The thickness of the adhesive strip is substantially the same as the thickness of the rear panel so that when the flap is opened, the overall configuration of the envelope is flat to facilitate stacking and feeding. The combination of the strip and the rear panel are both secured to the back side of the front panel, and the combination adds a layer of a uniform thickness to provide the desired flat aspect. Like such envelope constructions are arranged in a stack within a paper tray. The topmost one of the envelope constructions is separated from the stack seriatim at high speeds to feed them individually to the printer for printing thereon.
