Apparatus and method of producing flexible packages having an automatic closure feature

摘要

A reclosable flexible package (10) is suitable for retail sale of food products and is comprised of a film material. The reclosable flexible packages (10) are suitable for mass production on high-speed form-fill-seal equipment. The flexible package includes a pair of semi-rigid strips (14,16) attached to the walls of the flexible pouch and positioned parallel to the package opening. The semi-rigid strips (14,16) are configured and arranged to nest together and bias toward one another. Upon opening of the package, the semi-rigid strips (14,16) are moveable between a closed position and an open position. Further, the semi-rigid strips (14,16) are configured such that they automatically reclose the package when the strips are released from the open position.
