ABSTRACT:
A resealable packaging enclosure is disclosed which includes a tear path defining an aperture through which products may be extracted from the enclosure, and a resealable closure tab which extends across the tear path. The tear path includes weaker and stronger portions. The stronger portion is more resistent than the weaker portion to forces tending to separate the material comprising the enclosure along the tear path. Thus, the tear path has a variable resistance along its length to forces tending to open the enclosure.
