Patent US 7,201,305

A continuous feed, multipart, multilayer form having detachable pin feed edges on each side sized to fit a pin feed impact printer for producing a postal envelope system is disclosed. Each part of the multipart form may have a top sheet, an outgoing envelope, an information sheet and a reply envelope. A series of coatings may be selectively applied to parts of the multipart form so that information impact printed on top sheet produces an addressed and sealable reply envelope, and an information sheet, removably contained within a sealed and addressed outgoing envelope including a postage permit.
