A system for applying a protective layer to a substrate, such as an electronic device, includes the protective layer, a dust removal layer on a contact surface of the protective layer, and a release film, or release liner, on a dust removal surface of the dust removal layer. The system may also include an application liner on an outer surface of the protective layer, opposite from the dust removal layer. A dust removal adhesive on the dust removal surface may clean a surface of the substrate to which the protective layer is to be secured. The dust removal layer may include two or more separate or separable sections, as well as pair of adjacent tabs on opposite sides of a boundary between adjacent sections of the dust removal layer. The adjacent tabs may facilitate removal of the adjacent sections of the dust removal layer from the contact surface of the protective layer to facilitate adhesion of the protective layer to the surface of the substrate. Methods for cleaning the surface of an electronic device in connection with securing a protective layer to the surface are also disclosed.

A shield that is attachable to a touch sensitive screen is disclosed. The shield may be attached to the touch sensitive screen only at its outer peripheral portion. An air gap is enclosed between the shield and the touch sensitive screen to form a planar air bearing. The shield preferably does not touch the active area of the touch sensitive screen when the user is not touching the shield but only viewing the touch sensitive screen through the shield. This mitigates unwanted optical artifacts such as trapped air bubbles, Newton rings and chromatic interference while maintaining the sensitivity of the touch sensitive screen.

A patterned pressure-sensitive adhesive tape includes a pressure-sensitive adhesive layer. The pressure-sensitive adhesive layer is formed by a pressure-sensitive adhesive composition for patterned pressure-sensitive adhesive tape. An elongational viscosity of the pressure-sensitive adhesive composition measured at 30 C. is 1,000 mPa.Math.s or greater and 650,000 mPa.Math.s or less, or a Trouton's ratio thereof measured at 30 C. is 8 or greater and 400 or less. The pressure-sensitive adhesive layer has two or more pressure-sensitive adhesive portions (B) and a non-pressure-sensitive adhesive portion region having no pressure-sensitive adhesive portions (B) between the two or more pressure-sensitive adhesive portions (B). The non-pressure-sensitive adhesive portion region is patterned to lead to an outer periphery of a sheet plane.

An attachment structure includes a main body and a first adhesive layer. The main body has an upper side as a first side and a lower side as a second side. The first adhesive layer is selectively disposed on one of the first and second sides. The first adhesive layer has multiple first passages. The first passages divide the first adhesive layer into multiple first adhesive blocks. By means of the first passages of the first adhesive layer, when the main body is attached to another unit, the main body can be more easily and tightly attached to the unit without producing any void or blister.

The present invention is directed to a safety reflective device for domestic safety. The safety reflective device can be in the form of reflective strip and reflective decal, and can be produced in different shapes and sizes. The safety reflective device comprising a high intensity prismatic reflective layer and an ultra-strong adhesive layer adjacent to the prismatic reflective layer.

The described embodiments relate to a sensor patch that can be temporarily removed and re-applied in the same location using a side element of the sensor patch. The side element can be folded onto the sensor patch when the sensor patch is adhered to an object such as an appendage of a person. The side element can be unfolded and adhered to the appendage in order to preserve the placement of the sensor patch on the appendage. In this way, maintenance such as cleaning can be performed on the area where the sensor patch is located without having to dispose of the sensor patch. Once maintenance is completed, the side element can be folded back onto a surface of the sensor patch until maintenance is to be performed again.

A composite film includes a first thermoplastic elastomer film layer and a second thermoplastic elastomer film layer, wherein the first thermoplastic elastomer film layer includes a first styrenic block copolymer. The second thermoplastic elastomer film layer is disposed on the first thermoplastic elastomer film layer, wherein the second thermoplastic elastomer film layer includes a second styrenic block copolymer, diffusion particles dispersed in the second thermoplastic elastomer film layer, and a surface microstructure disposed on the surface of the second thermoplastic elastomer film layer.

A binding tape (10) includes an intermediate layer (11), and a first surface layer (16) covering one surface of the intermediate layer (11). The intermediate layer (11) has a plurality of first linear members (12) arranged side by side at an angle with respect to a longitudinal direction (D1) of the binding tape (10).

A polymeric tape comprises a facestock extending lengthwise, the facestock including a polymer. An adhesive layer is on a first surface of the facestock. Tear-cuts are formed into at least one longitudinal edge of the facestock and extending inwardly, the tear-cuts being provided all along the at least one longitudinal edge of the facestock.

A pressure sensitive adhesive surface that does not adhere to the adherend and can be positioned by sliding it under low pressure, while it can exert a sufficient adhesive force under a pressure above a certain level. The adhesive sheet includes an adhesive layer with a fine structure on a surface thereof. The fine structure includes a plurality of cone or frustum structures, with the cones or frustums having two or more parts joined to each other via an interface. A first part is present on a top of the cones or frustums and is formed from a non-adhesive or a weak adhesive material, and a second part is present below the first part and is formed from a strong adhesive material.
