A double sided tape for detachably mounting a flexible printing plate to a flexographic printing press cylinder includes pressure-sensitive adhesive layers on opposed sides of a coextruded multilayer carrier having a core formed of a thermoplastic elastomer containing a uniform distribution of voids and one or more skin layers formed of film-forming thermoplastic polymer. The cellular thermoplastic elastomer is constructed to accommodate compressibility loads imposed during printing and to resist shear and tensile loads imposed during tape removal.

Method of making and using a flexographic plate mounting tape

Fastening systems for releasably securing two components together include tab and landing members. In a first arrangement, a Z-fold tab member has combined mechanical and adhesive engagement. A second arrangement includes adjacent adhesive and cohesive contact portions. A third arrangement contoured apertures and mechanical engaging elements. A fourth arrangement includes apertures and mechanical engaging elements sized and arranged so that each aperture receives a plurality of mechanical engaging elements. A fifth arrangement includes tab and landing members that cooperate to provide a color indicia of secure adhesive engagement.

Z-fold diaper fastener

The present invention is directed toward multilayer pressure-sensitive adhesive constructions with improved convertibility and aging. In one embodiment, the multilayer constructions have one layer formed of a first adhesive composition having a first glass transition temperature, and also having a tangent delta greater than about 0.5 at 10 radians per second at 20&deg; C., and a storage modulus greater than about 3&times;10 dynes/cm at 10 radians per second at 20&deg; C. At least a second adhesive layer is provided in the construction, the second adhesive layer comprising a second adhesive composition with a second glass transition temperature.

Multilayer pressure-sensitive adhesive construction

Heat resistant, pressure sensitive adhesive labels, tapes and similar constructions are provided, and comprise a heat resistant face stock laminated to a pressure sensitive adhesive and a release liner. In one embodiment, the face stock is a crosslinked polyolefin. In another embodiment, the face stock is a unitary coextrudate of two or more layers of polymeric material, an outer layer of which is a heat resistant polymer such as nylon 6. The heat resistant constructions are useful as electrophotographically printable labels and tapes.

Heat resistant pressure sensitive adhesive constructions

The present invention is directed toward a multilayer, pressure-sensitive adhesive construction wherein one layer is formed of a first adhesive composition having a first glass transition temperature, and at least a second layer is formed of a second adhesive composition having a second glass transition temperature. The first glass transition temperature differs from the second glass transition temperature by from about 10.degree. C. to about 50.degree. C.

Multilayer Pressure-sensitive adhesive construction

Release surfaces comprising extruded polymer-siloxane block copolymer mixtures are provided. At least one block of the copolymer is a polymer compatible with the bulk polymeric material, while a second block is polysiloxane. Coextruded release surfaces comprising two or more polymeric layers, including one layer of a polymer-siloxane block copolymer mixture, are provided. The release surfaces serve as release liners for pressure sensitive adhesive labels and tapes.

Block copolymer release surface for pressure sensitive adhesives

A release liner providing a release surface which comprises a first olefin polymer film formed having dispersed therein by high shear mixing a release substance which is polyethyleneimine octadecyl carbamide, polyvinyl octadecyl carbamate or a mixture thereof, coextruded or cocast onto a film formed from a second olefin polymer. The release liner has particular utility in diaper tape application.

Release films formed by coextrusion

A hot melt pressure sensitive adhesive composition comprising a tackified ethylene-propylene rubber modified with a copolymer of a styrene ethylene-propylene block copolymer and/or a styrene ethylene -butylene block is provided. The pressure sensitive adhesive exhibits high cohesive strength and adhesion to polar and apolar surfaces.

Flexographic plate mounting tape

There are provided pressure-sensitive adhesives which comprise free radical cured mixtures of at least one crosslinkable olefin polymer and at least one tackifying organic additive, preferably a hydrogenated additive, which is substantially nonresponsive to action of free radicals and present in an amount sufficient to tackify the cured mixture of polymer and additive.

Olefin polymer based pressure-sensitive adhesives

Thermoplastic elastomers provide autoadhesive properties at room temperature having improved anti-blocking properties. The elastomers are substantially non-adhesive. The elastomers include physical cross-links which enable the elastomers to be formed as laminates with other polymeric materials by processing techniques involving application of heat.
