Abstract (en)
A flexible tandem package (100) which can be readily separated into two, distinct recloseable packages (110, 210) and the method for making the same is disclosed. The package includes first and second sheets (116, 114) sealed to opposite surfaces of a double recloseable seal fastener assembly (127). The film sheets (116, 114) are further sealed hermetically together around the periphery (144, 244) of each of the easily separable two distinct packages. Parallel lines of weakening (170, 270) disposed in the central portion of the recloseable seal fastener assembly provide tamper-evident tear strips for each of the two distinct packages (110, 210). <IMAGE>
