Abstract
An envelope sheet assembly for stand-alone use, or for securing into a brochure or binder, includes multiple sheets overlying one another so that the assembly is of uniform thickness to facilitate laser, offset, flexograph printing or the like 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 protecting the adhesive coated flap. The sheet assembly may frame 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.
