A closure system for a film wall package includes profile strips having a reclosable seal of the inter- locking type, flange elements and, adjacent the reclosable seal, an adhered strip of peelable material. The peelable material and the profile strip may be co-extruded. With packaging film attached to the pro- file strips, typically to the flange elements, the re- sulting product may be used in a horizontal form, fill and seal operation, at which time the reclosable ele- ments are mated and a peel seal is formed. The peel seal may be disposed on either side of the reclosable seal with respect to the interior of the package. The benefits of both peel seals and reclosable seals may be obtained by using optimum materials for those elements while, at the same time, allowing the use of a differ- ent material for the walls of the package.
