ABSTRACT:
A reclosable bag includes a detachable reclosure tie having a tail portion formed by a series of spaced elongated seals and a closed loop. Apparatus for forming the reclosure tie with a bag includes first and second sealing jaws with external and internal grippers for holding web material. The first sealing jaw carries cutting and perforating knives and a cooling block that directs cooling air onto the knives to prevent the knife temperature from rising to the melting temperature of the web material. Each sealing jaw contains a heating block with complementary sealing surfaces for forming various seals including the seals that form the tail portion of the reclosure tie.
