Abstract
The zipper for a reclosable bag includes a male profile and a female profile. The female profile includes first and second legs extending from a planar base, with a space formed therebetween for insertion of a male profile therein. Apertures are formed in the planar base providing communication between the space between the first and second legs and an opposite side of the planar base. This allows the insertion of the male profile into the female element to urge particles or powder lodged in the space to pass through the apertures to the opposite side of the planar base.
