Abstract: A machine direction method of manufacture of reclosable packages is disclosed wherein a semi-circular or similarly shaped perforated pattern is punched in the web in registration with the package side seals. Continuous lines of perforation are punched in the web parallel to the top of the package. The web is folded and shaped into a package with a header which includes the semi-circular perforated pattern and the lines of perforation. A similar transverse direction method of manufacture is disclosed. When the top corner of the header is pulled, the header tears along the shaped perforation until it meets the horizontal line of perforation, thereby avoiding tearing through the area of the header that is sealed to the zipper flange, the header then tears along the horizontal perforation and finally follows the shaped perforation on the opposite end of the package.
