ABSTRACT:
An apparatus and a method for forming reclosable storage containers are provided to form and seal pouches containing products such as consumer food products. The film material handled thereby and the pouches thus formed include an access opening assembly having a reclosable closure assembly that is characterized by mating flexible closure strips having interlocking means that permit the consumer to easily open and readily and positively reclose the formed pouch. The apparatus and method engage together mating strips of film material sheeting to form a substantially closed web of sheet material that is generally spread or flattened and otherwise handled in order to minimize the formation of kinks and the like in seals formed by the apparatus and method.
