Abstract:
1. A method of making a reclosable container with a zipper, comprising the steps of: providing a zipper which comprises first and second profiles each having a portion extending longitudinally of the profile and being shaped for releasable engagement with the corresponding portion of the other profile, at least one of the profiles having a longitudinally extending flange portion; providing a substrate; applying a sealing means thereby sealing the longitudinally extending flange portion to the substrate, wherein the flange portion includes: a first antiseal zone which does not seal to a substrate during the step of applying the sealing means; a second line-of-weakness-forming zone which forms in said substrate, by said step of applying a sealing means, a line of weakness extending in the longitudinal direction of the zone; and a third seal zone which forms a longitudinally-extending seal with the substrate during the step of applying the sealing means, formed simultaneously with formation of said second, line-of-weakness forming zone during the step of applying the sealing means; and wherein the step of applying the sealing means includes the steps of applying heat and pressure and is applied to the first, second and third zones.
