ABSTRACT:
A recloseable plastic bag having male and female interlocking profiles which are easily openable and easily closeable, and a method of making such bag are disclosed. The bag includes mating profiles which comprise a selected non-engaging section such that the profiles cannot interlock at that section. The non-engaging section permits a user to more easily open the bag when the separating action of the profiles is initiated at the non-engaging section. The non-engaging section also permits air to escape as the bag and profiles are pressed together to close, to enable easier closing of the bag when product is contained therein.
