Cross folded, pressure sealed multi-page paper assembly and methods of making same

Abstract

A cost effective, pressure-sealed, multi-page paper assembly is configured as a mailer-type of assembly for use as a business form, direct mail piece or other document to distribute information to end-users. The multi-page paper assembly is formed from a single ply or sheet of paper that permits use of such cost-saving technologies as laser printing and imaging of the single ply or sheet. The multi-page paper assembly includes a central transverse line of cross fold perforations and a plurality of lines of fold assist perforations that permit the single ply or sheet to be folded into a desired Z-fold, C-fold, eccentric C-fold, V-fold, double parallel-fold or other folded configuration having a number of inboard panels to serve as pages of the assembly. Deposits of pressure-activated cohesive along one or both surfaces of the single ply or sheet are placed to define those panels to serve as inboard boards and to adhere portions of the ply or sheet when folded. Cohesive deposits can form seals and thereby a secure seal multi-page paper assembly when pressure-sealed to protect contents. Use of low-tack deposits can form unsecured seals for use with direct mail pieces. Removal of stub portions of the paper assembly permits the sealed assembly to be opened in a book-like manner along the sealed cross fold perforations and access provided to the multiple of pages contained therein.
