The double-sided pressure-sensitive adhesive sheet according to one aspect is a double-sided pressure-sensitive adhesive sheet for bonding a polishing pad to a surface plate, for bonding a polishing member to the surface plate, or for forming the polishing member, the pressure-sensitive adhesive sheet including a sheet-shaped base material, and a first pressure-sensitive adhesive layer and a second pressure-sensitive adhesive layer provided on each main surface of the base material, where at least one of the first adhesive layer and the second adhesive layer is a pressure-sensitive adhesive layer that is formed from a pressure-sensitive adhesive including an acrylic-based copolymer having a specific composition and a specific molecular weight, a tackifier resin having a specific amount, and a tolylene diisocyanate trimethylolpropane adduct, the pressure-sensitive adhesive layer having a gel fraction of 5 to 50% by mass.

A printable 2-PLY security tape includes a first tape PLY label stock. A first substrate has a printable outer surface as a first outer PLY surface. A first inner PLY surface includes at least one first release area disposed on an inside surface of the first substrate, and at least one first adhesive area is disposed on the inside surface of the first substrate. A second tape PLY security tape includes a second substrate outer surface as a second outer PLY surface. A second inner PLY surface includes at least one second release area disposed on an inner surface of the second substrate, and at least one second adhesive area disposed on the inner surface of the second substrate. The second adhesive area is in contact with the first release area and the first adhesive area in a contact with the second release area, to form a 2-PLY composite tape.

Systems and methods are disclosed for a multi-layered sound absorption structure. The multi-layered sound absorption structure may include a form material, an acoustic material disposed on a surface of the form material, and a construction material disposed on the acoustic material. The acoustic material may couple to the construction material during curing of the construction material. After the construction material is cured, the form material may be removed exposing a least a portion of the acoustic material.
