Method of producing a sealing system for a reclosable webbed-wall package, and system made

A profile strip including reclosable seal means, having a strip of peelable material, heat sealable to form a peelable seal, co-extruded on the profile strip substantially parallel to and proximate the reclosable seal means, wherein the reclosable seal means comprise a material different than the peelable material, and a flange, a portion of the flange being thickened to facilitate bonding said flange to a package wall without also heat sealing the strip to a mating profile strip in the area of the thickened flange.

A method of producing a sealing system for a package comprising the steps of:

• forming first and second profile strips, each strip comprising longitudinally-extending reclosable seal means and a flange adapted for bonding to a package wall, a portion of at least one of the flanges being thickened to facilitate bonding said flanges to the package wall without also heat sealing the strips together in the area of the thickened flange;
• and
• disposing on at least the first of the profile strips a length of peelable material capable of forming a peel seal with the second profile strip, the peelable material being disposed intermediate the flange and the reclosable seal means of the first strip.

An article of manufacture comprising:

• first and second elongate closure strips respectively having formed thereon first and second zipper elements and respective first and second flanges adapted for subsequent bonding to packaging material to form walls of a package, a portion of at least one of said first and second flanges being thickened to facilitate bonding said flanges to packaging material without also heat sealing the strips together in the area of the thickened flange;
• and
• an elongate strip of peelable material formed longitudinally along at least one of said first and second closure strips proximate the zipper element for forming a peel seal between the first and second elongate strips, wherein said peelable material is different than the material comprising the zipper element and forms said peel seal by heat sealing.

A package having walls secured to two mating profile strips, the package comprising:

• first and second elongate closures each located on one of the profile strips, the closures respectively comprising reclosable elements for selectively separating and joining the first and second closures, the closures being bound together by an elongate peel seal formed to one side of the reclosable elements, the peel seal being formed between strips of peel seal material, heat sealed to form a peelable seal, formed longitudinally on the profile strips, wherein the peel seal material is different than the material comprising the reclosable elements, the profile strips further each comprising a flange adapted for bonding to the package walls, a portion of at least one of the flanges being thickened to facilitate bonding said flanges to the package walls without also heat sealing the strips together in the area of the thickened flange;
• and
• package walls extending along sides of the first and second closures and respectively affixed thereto.
