Sealing tape roll
A sealing tape roll comprises a sealing tape of flexible, compressible foam with at least one interior barrier layer. The sealing tape is wound up into the sealing tape roll in such a way that a top surface of one turn rests against a bottom surface of an adjacent turn of the sealing tape roll, and side surfaces of the sealing tape form end surfaces of the sealing tape roll. The sealing tape comprises a plurality of foam plies, which are arranged one above the other in a thickness direction between the bottom and top surfaces of the sealing tape. A barrier layer is between each pair of adjacent foam plies. The at least one barrier layer extends over at least 50% of the width of the sealing tape roll between the opposite end surfaces of the sealing tape roll and in a longitudinal direction of the sealing tape.
Suction fixing sheet
The suction fixing sheet of the present disclosure is a suction fixing sheet to be placed on a suction surface of a suction device to prevent contact between a suction target and the suction surface. The suction fixing sheet includes a porous sheet having air permeability in its thickness direction; and a double-sided pressure-sensitive adhesive sheet provided with a substrate, having air permeability in its thickness direction, and disposed on one surface of the porous sheet, or a double-sided pressure-sensitive adhesive layer unprovided with a substrate, formed of a crosslinked pressure-sensitive adhesive, having air permeability in its thickness direction, and disposed on one surface of the porous sheet. The ratio of the thickness of the porous sheet to the thickness of the double-sided pressure-sensitive adhesive sheet or the double-sided pressure-sensitive adhesive layer is 8.0 or more.
