Machine feedable envelope

An envelope sheet assembly for securing into a brochure or binder includes multiple sheets overlying one another so that the assembly is of uniform thickness to facilitate printing thereon. The envelope sheet assembly is preferably 8½ inches by 11 inches in size, and the envelope is preferably 11 inches by 4½ inches. Permanent pressure sensitive adhesive is employed to hold the sheets together and to form the envelope. The adhesive is also applied to the sealing flap, with a removable strip coated with a suitable release agent (i.e. silicone) protecting the adhesive coated flap. Perforations permit easy removal of the envelope from the assembly. The perforations can have a cut and tie pattern wherein the ties attach the envelope to the sheet assembly. The sheet assembly frames the envelope at all outside edges of the envelope or some of the outer edges of the sheet assembly can form outer edges of the envelope.
