Abstract: A fastener tab including a fastening-tape-segment, a hook-tape-segment, a release-tape-segment, and an antipeel-tape-segment, with the release-tape-segment and the antipeel-tape-segment being formed from a single tape. The antipeel-tape-segment is configured to prevent a susceptible leading edge of an anchoring zone of the release-tape-segment from being subjected to peel-initiating forces during deployment of the fastener tab. An adhesive area can be included to releasably bond a fastening deployment zone and the release anchoring zone together to minimize pre-deployment flagging.

Abstract: An attachment/detachment fastening system comprising a backing, an adhesive on one side of the backing, and a weakened joint in the backing whereby the backing is foldable and tearable along the weakened joint. The backing and adhesives for the fastening system are chosen based on the end application. Suitable backing materials include polymers, papers, and metal foils. Suitable adhesives include pressure-sensitive adhesives and heat-set adhesives. The weakened joint may be formed by mechanical means, such as scoring, slitting, or perforating the backing, or by chemical means such as acid dripping or etching. The fastening system of the present invention is useful in various applications, including joining together products for shipping and sale, e.g., attaching a promotional product to a product to be sold, and as tamper-evidence labels.

Abstract: A fastening system for releasably securing a diaper provides both mechanical and adhesive or cohesive securement. Tab members comprise a facestock layer, a contact layer of adhesive or cohesive overlying at least a portion of the facestock layer, and mechanical fastening elements projecting from at least a portion of the contact layer. The facestock layer includes extensible and substantially nonextensible polymeric portions. A landing member includes complementary mechanical fastening elements and a contact surface or cohesive for engagement with the tab adhesive or cohesive. A method is also disclosed for making the fastening system.

Abstract: An extensible tab fastener for a disposable diaper comprises a laminate of an extensible facestock and an ordinarily nonextensible mechanical fastener. The nonextensible mechanical fastener is rendered extensible by providing in at least the nonextensible portions thereof a plurality of separation interfaces or parting planes extending through the thickness of the nonextensible portion or portions at spaced locations in the direction of desired extensibility.

Abstract: A process for the manufacture of a plastisol film or foam tape laminate comprises providing a continuous liner; forming a release layer along the length of one side of the liner; depositing an adhesive onto the release layer; drying the adhesive; casting a liquid plastisol formulation onto the adhesive; fusing, and in the case of a foam tape, expanding the plastisol formulation to form a thermoplastic layer on the adhesive; and, winding the resulting tape laminate onto rolls.

Abstract: An adhesive strip is described which comprises(A) a polymer backing sheet material;(B) a controlled adhesion coating on one surface of said sheet material, said coating comprising a radiation-cured mixture comprising(B-1) a major amount of at least one acrylate oligomer selected from amine acrylate oligomers, epoxy acrylate oligomers, urethane acrylate oligomers and acrylic acrylate oligomers, and(B-2) a minor amount of at least one monomer selected from monofunctional acrylate monomers and polyfunctional acrylate monomers, and(C) an adhesive on the other surface of said sheet material.Articles such as disposable diapers also are described which utilize the strip as a target strip or landing zone for pressure-sensitive adhesive fastening tabs when the diaper is fastened around the body.
