  • Publication number: 20220346625
    Abstract: Provided is, for example, a cleaner sheet including: a cleaning surface that is configured to be brought into sliding contact with a surface of an object to be cleaned. The cleaning surface has unevenness, and includes projections respectively having distal ends configured to be in sliding contact with the object to be cleaned when in use. The projections are constituted by a member formed to have the projections arranged at intervals from each other in a plane direction of the cleaning surface. The member has a hardness of 0.4 MPa or more measured by a nano-indentation method. The cleaning surface further includes adhesive recesses that have higher adhesive force than that of the member and are exposed on the cleaning surface.

  • Publication number: 20200323416
    Abstract: Provided is a sticky cleaner whose adhesive face can be easily renewed and whish is less susceptible to roll-loosening. The sticky cleaner provided by this invention comprises a PSA tape having an adhesive face on the first face of a substrate. The PSA tape forms a PSA tape roll wound with the adhesive face on the outside. On the first face of the substrate, the PSA tape comprises a first layer formed of a PSA and a second layer formed of an acrylic viscoelastic material. The adhesive face comprises first sections where the first layer is exposed and second sections where the second layer is exposed. The second sections protrude further out of the PSA tape roll relative to the first sections. The PSA tape roll shows an unwinding force F0 at 0° C. and an unwinding force F30 at 30° C.

  • Patent number: 6455151
    Abstract: A base film for pressure-sensitive adhesive tapes and sheets which comprises a tackifier resin; and a pressure-sensitive adhesive tape or sheet which has a film having at least one layer of the base film as a substrate and a pressure-sensitive adhesive layer formed on at least one face of the substrate. Pressure-adhesive tapes or sheets which have excellent effects of undergoing little dimensional change even under heating or with the passage of time, showing good appearance without suffering from gapping, etc. in case of rolled tapes and sustaining stable pressure-sensitive adhesive force. Particularly favorable effects can be achieved in pressure-sensitive adhesive tapes wherein a polyolefin resin is used as the base film and a rubber pressure-sensitive adhesive containing a large amount of a tackifier resin is used as the pressure-sensitive adhesive.
