Abstract

An improved reclosable fastener profile assembly is provided, said assembly comprising a continuous supply of a first profile strip this first profile strip being substantially flat but having at least one rib that extends from the surface of first strip; and a continuous supply of a second profile strip opposite the first strip; this second strip being substantially flat but having at least two ribs that extend from the surface of this second strip. The rib of the first stπp and the ribs of the second strip are adapted to sealingly engage and maintain an airtight seal when so engaged. A compression molded segment seal portion fuses the first profile stπp, the second profile strip and the ribs of the first profile, strip and second strip. The compression molded segment seal includes a fused section of the first and second profile strips.
