Abstract

Abstract Microtextured elastomeric laminate tape comprising a laminate with at least one elastomeric layer and at least one thin skin layer, and an adhesive layer, preferably prepared by coextrusion of the layers followed by stretching the laminate past the elastic limit of the skin layers and then allowing the laminate tape to recover.

Claims Analysis

Total Claims: 23
Claim 1
Independent Claim 75 words
An elastomeric laminate tape consisting essentially of an elastomeric laminate comprised of at least one elastomeric layer and at least one outer skin layer wherein the at least one skin layer has a microtextured skin layer surface formed by inelastic deformation of the at least one skin layer in more than one direction and at least one substantially continuous pressure-sensitive adhesive layer in continuous contact with said at least one skin layer of said laminate.
Claim 2
Dependent Claim 75 words
An elastomeric laminate tape consisting essentially of an elastomeric laminate comprised of at least one elastomeric layer and at least one outer skin layer wherein the at least one skin layer has a microtextured skin layer surface formed by inelastic deformation of the at least one skin layer in more than one direction and at least one substantially continuous pressure-sensitive adhesive layer in continuous contact with said at least one skin layer of said laminate.
Claim 3
Dependent Claim 23 words
The elastomeric laminate tape of claim 1 wherein the deformation of the at least one skin layer is created by sequential biaxial stretching.
Claim 4
Dependent Claim 30 words
The elastomeric laminate tape of claim 1 wherein the at least one skin layer having undergone inelastic deformation is an outer layer adjacent to said at least one adhesive layer.
Claim 5
Dependent Claim 27 words
The elastomeric laminate tape of claim 1 wherein said at least one adhesive layer has an undulating outer surface substantially corresponding to an adjacent underlying skin layer.
Claim 6
Dependent Claim 20 words
The elastomeric laminate tape of claim 4 wherein said at least one adhesive layer is less than 30 microns thick.
Claim 7
Dependent Claim 18 words
The elastomeric laminate tape of claim 1 comprising a removable label having a non-adhesive coated outer skin layer.
Claim 8
Dependent Claim 100 words
An elastomeric laminate tape comprising an elastomeric laminate comprised of at least one elastomeric core layer and at least one outer skin layer wherein the at least one skin layer has a microtextured skin layer surface formed by inelastic deformation of the at least one skin layer in at least one direction and at least one substantially continuous pressure-sensitive adhesive layer in continuous contact with at least the face of said laminate with the microtextured skin layer, wherein the adhesive thickness is such that its outer surface has an undulating texture corresponding to that of the underlying microtextured skin layer.
Claim 9
Dependent Claim 100 words

Claim 15
Dependent Claim 99 words
An elastomeric laminate tape comprising an elastomeric laminate consisting essentially of at least one elastomeric layer and at least one outer skin layer wherein the at least one skin layer has a microtextured skin layer surface formed by inelastic deformation of the at least one skin layer in at least one direction and at least one substantially continuous pressure-sensitive adhesive layer over at least the entire face of said laminate with the microtextured skin layer, wherein the adhesive layer and the underlying skin layer are in substantially continuous contact providing improved anchorage of the adhesive layer to the laminate.
Claim 16
Dependent Claim 99 words
An elastomeric laminate tape comprising an elastomeric laminate consisting essentially of at least one elastomeric layer and at least one outer skin layer wherein the at least one skin layer has a microtextured skin layer surface formed by inelastic deformation of the at least one skin layer in at least one direction and at least one substantially continuous pressure-sensitive adhesive layer over at least the entire face of said laminate with the microtextured skin layer, wherein the adhesive layer and the underlying skin layer are in substantially continuous contact providing improved anchorage of the adhesive layer to the laminate.
