Abstract:
A double-sided pressure-sensitive adhesive tape is used for fixing decorative panels and includes a pressure-sensitive adhesive layer containing bubbles and/or hollow microspheres. The pressure-sensitive adhesive layer is preferably formed from an acrylic pressure-sensitive adhesive, particularly an active-energy-ray-curable acrylic pressure-sensitive adhesive. The double-sided pressure-sensitive adhesive tape for fixing decorative panels preferably has a toluene emission of 15 μg/g or less and preferably has a surface lightness L* of 60 to 30. The adhesive tape can be a double-sided pressure-sensitive adhesive tape for fixing decorative panels, which excels in conformability to curved surfaces and bumps, resilience resistance, and adhesiveness and which may thereby show excellent adhesive properties even when used for fixing a decorative panel to an adherend of a complicated shape with a curved surface or bumps or for fixing a narrow decorative panel to an adherend.
Abstract:
A pressure-sensitive adhesive tape roll includes a bobbin and, helically wound therearound, a double-sided pressure-sensitive adhesive tape. The tape includes a double-sided pressure-sensitive adhesive body including a pressure-sensitive adhesive layer containing bubbles and/or hollow microspheres, and arranged on both sides thereof, a release liner A wider than the adhesive body, and an olefinic release liner B. In portions occupying 70% or more of the total length of the tape, a crosswise extending-off portion of the release liner A of an (n)th-turn portion of the adhesive tape vertically overlaps the adhesive body of an adjacent (n+1)th-turn portion of the adhesive tape to form an overlapping portion; the width of the overlapping portion is one half or more of the width of the adhesive body; and the adhesive body of the (n)th-turn adhesive tape is not present below the adhesive body of the adjacent (n+1)th-turn adhesive tape.
Abstract:
Disclosed is a method for joining two strips, where the two strips each include a laminate of a release liner and a pressure-sensitive adhesive layer, and the release liner extends from the corresponding pressure-sensitive adhesive layer in a longitudinal end region of at least one of the two strips. The method includes butting cross-sections of longitudinal ends of the pressure-sensitive adhesive layers of the two strips to bond the two pressure-sensitive adhesive layers; and superposing end regions of the release liners of the two strips and fixing the release liners so that surfaces of the release liners in portions at least 1 mm long inward from the longitudinal ends are not in contact with surfaces of the pressure-sensitive adhesive layers. This method gives a continuous strip from which the release liner can be smoothly removed without “binding” even at the joint.

Abstract:
A pressure-sensitive adhesive tape that can be used in a temperature environment of at least 90° C. or higher, includes: a pressure-sensitive adhesive layer; and a release liner provided on the surface on at least one side of the pressure-sensitive adhesive layer. The release liner has: a base layer containing a polyolefin resin; and a release layer that contains low-density polyethylene and is provided on at least one side of the base layer to be in contact with the pressure-sensitive adhesive layer.
Abstract:
Disclosed is a release liner having a multilayer structure of at least three layers including two surface layers and an intermediate layer, in which one of the two surface layers contains a high-density polyethylene, the other contains a low-density polyethylene, and the intermediate layer contains a low-density polyethylene alone as its resin component. Also disclosed is a pressure-sensitive adhesive sheet including the release liner and at least one pressure-sensitive adhesive layer, in which a release force X (N/mm) between the release liner and the pressure-sensitive adhesive layer and a rigidity Y of the release liner [(Young's modulus of the release liner)×(thickness)3] (N·mm) satisfy the following conditions: 0
Abstract:
The release liner includes a release layer constituted of at least one polyolefin resin, wherein the release layer has surface irregularities. The surface irregularities of the release layer may be constituted of recesses and protrusions which are irregularly different in shape and have been disposed in irregular arrangement. The release layer preferably has a surface roughness Ra of 1-3 μm. As the polyolefin resin constituting the release layer can be used at least one polyolefin resin selected from the group consisting of polyethylenes, polypropylene, polybutenes, poly(4-methyl-1-pentene), and copolymers of ethylene with one or more α-olefins having 3-10 carbon atoms.
Abstract:
A pressure-sensitive adhesive label has a base having an information indication portion on its one surface thereof, and a pressure-sensitive adhesive layer formed on another surface of the base. After peeling a release liner, the label is stuck on an outer surface of a housing of the hard disk drive to reduce noise generated when the hard disk drive is driven. The release liner for coating the pressure-sensitive adhesive layer has an antistatic function and a cut line. The adhesive force of the adhesive layer is reduced by heating. The label has a surface density of not lower than 0.18 (kg/m2).
