A label assembly including one or more dissolvable thermal direct adhesive labels and methods of assembly and use. According to one embodiment, each label includes a base layer, a thermal direct layer, an adhesive layer, and a barrier layer. The base layer, which has an upper surface and a lower surface, is water-dissolvable and may be made of a water-dissolvable paper. The thermal direct layer is positioned directly over the upper surface of the base layer and functions in the conventional manner to produce markings therein in response to heat. The adhesive layer is water-dissolvable and is positioned below the lower surface of the base layer. The barrier layer, which is positioned directly below the lower surface of the base layer and directly over the adhesive layer, serves to prevent migration of the adhesive layer through the base layer and into contact with the thermal direct layer.

A heat spreader for high volume manufacturing of a heat source, having a heat spreader composition which comprises a heat spreader material, an adhesive thereon, and a release material. The adhesive and release material are selected to prevent delamination of the heat spreader material when the release material is removed during the high volume manufacturing process of heat sources.

The present invention provides a photocurable adhesive composition. The photocurable adhesive composition comprises, based on the total solid content thereof, 10 to 40 wt % of a thermoplastic polymer containing carboxylic groups and epoxy groups, 20 to 50 wt % of an epoxy component, 1 to 10 wt % of a hydroxy-containing compound, and 0.1 to 5 wt % of a photoinitiator. The present invention further provides a photocurable adhesive tape comprising the photocurable adhesive composition. The photocurable adhesive composition and the photocurable adhesive tape prepared according to technical solutions of the present invention have excellent adhesiveness to phosphorus-containing nickel-plated substrates.

A multi ply plastic film to create a heat-sealed enclosure for food to be heated inside the enclosure save for a region of the heat-seal where a vent-opening can be established to allow gas and/or steam to escape the enclosure during heating of the food. The film has a primary panel to create the enclosure by heat sealing to itself or a separate panel or to a peripheral lip of a container There is also provided a release panel applied to said primary panel to be located intermediate of and to prevent the primary panel being heat-sealed to itself or peripheral lip at the peripheral heat-sealed region for the vent-opening to thereat be established.

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.

An optical clear adhesive film is provided. A first tearing part is disposed on a first side of a first protective film, such that when an external force is applied to the first tearing part, a starting position at which the colloid layer is separated from the first protective film is a line contact. Therefore, the colloidal layer is less stressed at each point of separation, and phenomenon that the colloid layer is pulled is avoided.

An adhesive sheet includes an adhesive layer having a fine structure on the surface. The fine structure includes a plurality of convex structures. The convex structures each have two or more parts. A first part located at the top portion of the convex structure is made from a non-adhesive or weak adhesive material. A second part located below the first part is made from a strong adhesive material. Given that a width of a bottom surface of the convex structure is a and a distance between bottom surfaces of adjacent convex structures is β in an arrangement direction of the convex structures, β/(α+β)<0.3 is satisfied.

The invention relates to a device that includes a substrate and a thin film of a photo-switchable adhesive layer applied to at least one surface of the substrate. A method of releasably supporting a product that includes adhering a product onto the thin film of the device and exposing the thin film to light sufficient to cause a change in the adhesive strength of the thin film. A method of making the device is also disclosed.
