Abstract

A reclosable back-seam bag having a top seal and a bottom seal, and a front wall and a back wall is disclosed. The front wall is joined to the back wall at the top seal and the bottom seal. The reclosable back-seam bag includes a reclosable fastener that includes two ends, a first continuous elongated profile strip having a front wall connecting flange and a second continuous elongated profile strip having a back wall connecting flange. The first continuous elongated profile strip includes a male interlocking profile having at least one male interlocking member, and the second continuous elongated profile strip includes a female interlocking profile having at least one female interlocking member. The male interlocking member is configured so as to cause the male interlocking profile to be separated from the female interlocking profile with a substantially equal opening force when being separated in a direction toward said top seal as when separated in a direction toward said bottom seal. At least one frangible access portion disposed substantially parallel to said reclosable fastener assembly may be provided to expose the releasable fastener assembly and / or the contents of the bag.
