ABSTRACT:
A pressure sensitive seal member for providing a complete adhesive-to-adhesive seal for the open end of a pouch includes a strip of face stock having a pressure sensitive adhesive on one face. There are two removable backing strips covering the adhesive and they are in edge contact along a generally longitudinal line. The face stock has a generally longitudinal fold perforation which is offset from the line of edge contact and is covered by one of the backing strips. When the seal member is applied, first one of the backing strips is removed with the fold perforation remaining covered. One side of the pouch open end is applied to the exposed adhesive surface. Subsequently, the other backing strip is removed exposing the fold perforation. The strip is folded and that portion of the adhesive covered surface on the opposite side of the fold and formerly covered by the backing strip is applied to the remaining side of the pouch. The face stock is adhesively secured to opposite sides of the pouch and there is adhesive-to-adhesive contact between portions of the face stock directly adjacent the pouch opening.
