A method of manufacturing a resealable closure mechanism includes separately extruding the interlocking closure member from its respective base strip. The interlocking closure member is cooled prior to bonding the base strip to the interlocking closure member. Bonding is accomplished by either heat sealing, adhering, pouring molten polymeric material, or ultrasonic sealing.
