Abstract
A reclosable bag has an open end which is closed by a closure strip which can be repeatedly reclosed. The closure strip preferably comprises a hook and loop fastener means which can be brought into engagement and a frangible section running lengthwise of the closure strip. The closure strip is adhesively sealed to the ends of the bag by adhesive sections on opposite sides of the frangible section. In one preferred embodiment of the invention, any opening force applied to the closure by the bag contents places the hook and loop fastener under shear stress only.
