An adhesive film with excellent cuttability with respect to both a base layer and a surface layer or layers laminated thereon is provided, without significant formation of adhesive burrs in various shearing processes. The adhesive film includes a support member and an adhesive layer laminated on at least one side of the support member. The adhesive layer has a laminate structure having a base layer made of a resin-based adhesive and laminated on the surface of the support member and a surface layer made of a resin-based adhesive and laminated on the base layer. The base layer is non-directional and has lengthwise and widthwise shearing strengths of 2 g to 2000 g [200 mm/min, 25 mm] in the thickness range of 2 μm to 60 μm. The base layer has a shearing strength of 1.5 to 200 times the shearing strength of the surface layer.

Provided are buffered adhesive compositions comprising a high molecular weight non-neutralized polymeric acid and a high molecular weight partially neutralized polymeric acid and products such as wound dressings and ostomy skin barriers incorporating the compositions.

Adhesive damping systems are described. A damping system for reducing the effects on a substrate caused by a disruption in the substrate environment includes an adhesive having a plurality of three-dimensional nanoparticles dispersed therein. The nanoparticles are configured to provide a controlled response to an applied force field. The system further includes a sensor which measures an amplitude and frequency spectrum of the disruption. In a use configuration, the sensor determines the amplitude and frequency spectrum of the disruption received by the substrate; and the applied force field is dependent on the amplitude and frequency spectrum of the disruption.
