Abstract
A reclosable bag for filling with at least one food product. The reclosable bag generally includes at least one sheet of web material having at least two areas of structural weakness. At least one fold structure is located between and defined by the two areas of structural weakness. An opening is located generally opposite the fold structure. The reclosable bag further includes a reclosable fastener structure having an integral skirt structure of skirt web material, including a distal margin, extending therefrom. The distal margin is coupled to the web material at, at least one location between the areas of structural weakness and the opening. The reclosable fastener structure extends past the areas of structural weakness and into the fold structure. The reclosable bag is capable of being filled with at least one food product through the opening.
