Abstract
Sealed envelopes of a continuous envelope assembly each include front and back panels and a return envelope contained therein. The return envelope is free of attachment to the sealed envelope along all its marginal edges, and is constructed as having a protective portion overlying its flap with such portion being attached to the sealed envelope so as to be retained therewith upon extraction of the return envelope. The return envelope is immobilized within the sealed envelope by retention chips in abutting engagement with the marginal edges of the return envelope. These retention chips are secured to the outer envelope and are defined by severed extensions of the return envelope.
