A cover tape for use with a carrier tape, where the cover tape includes at least one tear-initiation feature that defines a predetermined direction of tear to initiate a tear along portions of the cover tape.

Carrier tapes having tear-initiated cover tapes and methods of making thereof

An article includes a cover tape, which includes a base film layer, tear enabling features, and an adhesive. The base film layer has opposed longitudinal edges and top and bottom surfaces. The tear enabling features are substantially parallel to the longitudinal edges and at the top and bottom surfaces.

Cover tape and method for manufacture

A diaper construction is provided with an external porous reinforcement strip at the front part of the outside of the diaper, which strip provides reinforcement against an adhesive fastening tab and provides an oil contamination tolerant adhesion surface.

Oil-tolerant reinforcement strip

A diaper construction is provided with an external porous reinforcement strip at the front part of the outside of the diaper, which strip provides reinforcement against an adhesive fastening tab and provides an oil-contamination tolerant adhesion surface.

A pressure-sensitive adhesive and tape are provided having a rubber component (30-60 weight percent) of polyisoprene (4-55 weight percent) blended with a styrene-isoprene-styrene block copolymer (96-45 weight percent) and a tackifying component (70-40 weight percent) to provide an adhesive that exhibits superior adhesion performance to low surface energy substrates.

Pressure-sensitive adhesive and disposable diaper closure system

There is provided a laminate of a liquid additive containing microporous film with a hot-melt adhesive composition. The hot-melt adhesive is formulated with polybutylene polymers or copolymers with optional tackifiers and/or plasticizers such that the microporous film in the areas of adhesive contact has an L value of at least 70, most preferably at least 80. The liquid additive is preferably a plasticizing oil such as mineral oil.

Construction adhesive for porous film

A tape closure system exhibiting high shear and high non-shocky peel to a low adhesion backsize coated substrate is disclosed. The adhesive used on the fastening tape used in the closure system comprises a high diblock (.gtoreq.25 percent) styrene-isoprene-styrene elastomer component with a composite midblock glass transition temperature of 244 to 264 Kelvin with 30 to 60 percent elastomer.
