Abstract:
A grip tape includes: a flexible, elastic substrate having a top surface and a bottom surface; an adhesive layer applied to the bottom surface of the substrate; and a grip layer applied to the top surface of the substrate, the grip layer including a non-slip material having an elastic limit that is at least as great as an elastic limit of the substrate, and the top surface being substantially free of any adhesive material.
Abstract:
The aim of the invention is to improve an impairment to the adherence of an adhesive tape to a substrate caused by the inclusion of air bubbles between the adhesive tape and the substrate. According to the invention, said aim is achieved by means of an adhesive tape which comprises at least one adhesive layer, wherein the adhesive layer has at least one groove and none of the grooves extends as far as one of the lateral edges of the adhesive layer. The invention further relates to a release liner having a surface which has at least one ridge, wherein none of the ridges extends as far as one of the lateral edges of the release liner.
Abstract:
Systems and films for protecting surfaces of various substrates, including electronic devices, such as portable electronic devices, include a liner with a strip liner and a main liner. The strip liner, which covers a small strip of adhesive on the back side of a protective film, is configured to be removed before the main liner. With the small strip of adhesive exposed, the protective film may be aligned with a substrate and, if necessary, removed from the substrates and repositioned thereon. Thereafter, the main liner may be removed to enable complete application of the protective film to the substrate. Methods for securing protective films to substrates are also disclosed.
Abstract:
A base film for dicing sheets that is used in a dicing sheet comprising the base film and a pressure sensitive adhesive layer laminated on one surface of the base film. The base film comprises at least a first resin layer that is in contact with the pressure sensitive adhesive layer of the dicing sheet and a second resin layer that comes into contact with the first resin layer when the base film for dicing sheets is wound up. The second resin layer has a crystallinity of 28% to 45%, The ratio of a tensile elastic modulus of the first resin layer to a tensile elastic modulus of the second resin layer is 1.2 to 3.0. The ratio of a thickness of the first resin layer to a thickness of the base film for dicing sheets is 25% to 80%.

Abstract:
A hand-tearable masking tape with a primary microstructured hand-tear pattern and at least one secondary hand-tear pattern oriented so that the tape exhibits multi-directional tear.
Abstract:
A composite sheet 1 for forming a protective film which includes: a pressure sensitive adhesive sheet 2 obtained by laminating a pressure sensitive adhesive layer 22 on one surface of a base material 21; a protective film-forming film 3 laminated on the pressure sensitive adhesive layer 22 side of the pressure sensitive adhesive sheet 2; and a pressure sensitive adhesive layer 4 for jigs, the layer being laminated on a peripheral portion on the opposite side of the pressure sensitive adhesive sheet 2 side of the protective film-forming film 3, wherein a thickness of the pressure sensitive adhesive layer 22 of the pressure sensitive adhesive sheet 2 is from 1 to 8 μm.According to the composite sheet 1 for forming a protective film, it is possible to effectively suppress loosening of the sheet 1 in the heating step and the cooling step, and the dicing and picking up processes can also be performed satisfactorily.
Abstract:
A device for attaching an article of manufacture, such as a mobile phone, to a lanyard. The device includes a thin bendable sheet of material having an adhesive on at least one side. The sheet of material has an elongated portion having a first section and a second section, and the first section capable of being doubled-over and secured to the second section by the adhesive, so as to engage a clip from the lanyard. The sheet has a pair of opposed spirals extending away from each other and spiraling around toward the elongated portion. The spirals curve, or spiral, at least 180° from a beginning b of the spiral to an ending e of the spiral. The radius of curvature along the length of the spirals continuously decreases in a manner that approximates the shape of a Fibonacci spiral.
Abstract:
This invention provides a pressure-sensitive adhesive tape that comprises a polyvinyl chloride film comprising a plasticizer and a pressure-sensitive adhesive layer placed at least on one face of the film. The pressure-sensitive adhesive tape has a weight loss on heating of less than 4% and a holding power of 50 minutes or greater.
Abstract:
A semiconductor processing sheet, the sheet comprising a base material and a pressure sensitive adhesive layer laminated on at least one surface of the base material, the pressure sensitive adhesive layer being formed of a pressure sensitive adhesive composition, the pressure sensitive adhesive composition containing a polymer having a salt and an energy ray curable group and an energy ray curable pressure sensitive adhesive component (excluding the above polymer). The semiconductor processing sheet can suppress contamination of an adherent at the time of peeling after energy ray irradiation while exhibiting a sufficient antistatic property.
