Abstract
A reclosable sack having a mouth from which contents may be discharged, including a primary non-reclosable stitched fastener across and closing the mouth. The stitched fastener includes a removable chain stitch and tear strip for facilitating manual opening of the primary fastener. The reclosable sack also includes a secondary reclosable fastener having a pair of interlocking profile strips that are attached at lower inner wall portions to the upper edge of the sack walls outboard of the stitched fastener. The secondary profile fastener is heat sealed at its ends and allows the sack to be reclosed once the primary non-reclosable fastener has been removed.
