A process for applying a portion of a closed zipper inside a container of flexible material, in which a segment or portion of a closed zipper-strip is first applied by a fixing device upon the inner sides of a film of flexible material, prior to cutting of the zipper strip portion from the remainder of the zipper strip. The zipper portion is applied in such a position that it will not interfere with the subsequent sealing along transverse seal lines defining the opposite sides of the container. |
