Abstract
A reusable adhesive envelope and a method and apparatus for making same. The envelope includes a pouch adapted to receive the contents and having an open edge. A flap is mounted adjacent this open edge and may be folded about a flap fold to close the pouch opening. The exterior of the pouch mounts a protective strip. The interior face of the flap mounts a pressure sensitive adhesive, which is initially covered by a release liner. Upon removing the release liner the adhesive on the flap may be secure to the protective strip to close the flap. The flap may be opened and reclosed numerous times. The protective strip and the adhesive/release liner combination are each applied to the envelope as tape strips. With the envelopes in the open configuration these tape strips are alternately applied from a single transfer mechanism.
