Abstract

Touch fasteners useful for bags, packaging and other products as well as novel manufacturing of products incorporating such fasteners. A composite touch fastener has a fibrous loop strip partially encapsulated in, or otherwise permanently attached to, resin of a substrate, and an array of loop-engageable fastener elements integrally molded with resin of the substrate. The center portion of the closure seals the bag until it is torn away to expose the mating bands of loops and fastener elements. Methods of applying recloseable touch fasteners, e.g. hook and loop fasteners, to sheet or film include vertical form and fill and horizontal form and fill packaging and pouch making.
