Abstract: An optical film includes a plurality of alternating first and second polymeric layers disposed on a first protective layer. Each of the first and second polymeric layers has an average thickness less than about 500 nm and the first protective layer has an average thickness greater than about 750 nm. An olefin layer can be disposed on the first protective layer opposite the plurality of alternating first and second polymeric layers. The olefin layer includes cyclic olefin copolymer, cyclic olefin polymer, or a blend thereof. The olefin layer can have an unstructured major surface opposite the first protective layer. A bonding layer is disposed between, and bonds together, the olefin layer and the first protective layer. The optical film is integrally formed.

Abstract: The present disclosure provides a core-sheath filament. The core-sheath filament includes an adhesive core and a non-tacky sheath, wherein the sheath exhibits a melt flow index of less than 15 grams per 10 minutes. The present disclosure also provides a method of printing an adhesive. The method includes a) melting a core-sheath filament in a nozzle to form a molten composition, and b) dispensing the molten composition through the nozzle onto a substrate. Steps a) and b) are carried out one or more times to form a printed adhesive. The core-sheath filament includes an adhesive core and a non-tacky sheath. Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying an article; and generating, with the manufacturing device by an additive manufacturing process using a core-sheath filament, the article including a printed adhesive based on the digital object. A system is also provided, including a display that displays a 3D model of an article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of an article including a printed adhesive, using a core-sheath filament.

Abstract: A core-sheath filament including a crosslinkable adhesive core that can be cured using ultraviolet or visible light radiation. These crosslinkable adhesive core compositions can provide very high bond strength and are capable of replacing traditional mechanical fasteners in many industrial applications. Core-sheath filaments including such crosslinkable compositions, crosslinked compositions, articles containing these compositions, and methods of making the articles are provided. The crosslinkable compositions contain pendant aromatic ketone groups or pendant (meth)acryloyl groups that, upon exposure to ultraviolet radiation, result in the formation of crosslinks within the polymeric material. The crosslinked compositions can function as pressure-sensitive adhesives.

IPC: C09J7/28

Abstract: The disclosed film backing has a multilayer extensible substrate with a securing adhesive that can secure to a surface and a tab to stretch the extensible substrate to remove the securing adhesive from the underlying surface. Stretching the extensible substrate will easily release the adhesive from the underlying surface. Therefore, a strong adhesive can be used. The multilayer extensible substrate includes an elastic layer forming the core adjacent to a plastically-deforming layers forming the skin to minimize the elasticity of the overall construction.

Abstract: A method of making an adhesive article is described comprising melt extruding a core film layer comprising a composition comprising at least 50% of a polylactic acid polymer. The method further comprises melt extruding an adhesive layer on a major surface of the core film layer such that regions of interdiffusion are present between the core film layer and adhesive layer. The adhesive layer may comprise C1-C10 (meth)acrylic acid or ester thereof, vinyl acetate, ethylene vinyl acetate, hydrolysed polyvinyl alcohol and combinations thereof. The adhesive layer may also be a pressure sensitive adhesive. The method further comprises melt extruding a release film layer on an opposing major surface of the core film layer. The layers are sequentially extruded or co-extruded and can be uniaxially or biaxially oriented. Articles comprising a core film layer comprising a composition comprising at least 50% of a polylactic acid polymer and an adhesive layer disposed on a major surface of the core layer are also described.

Abstract: Polymeric multilayer material includes an adhesive layer having first and second opposed major surfaces. A first foam layer is joined to the first major surface and includes a first plurality of expandable microspheres. A first skin layer is attached to the first foam layer and is free of the first plurality expandable microspheres. A second foam layer is joined to the second major surface of the internal adhesive layer and includes a second plurality of expandable microspheres dispersed therein. A second skin layer is attached to the second foam layer and is free of the second plurality of expandable microspheres. A portion of the first expandable microspheres of the first foam layer and of the second foam layer is at least partially embedded within the adhesive layer. Embodiments, of polymeric multilayer materials described herein are useful, for example, as wearable medical or athletic support components. The materials can also be used as protective wrappings. For example, the materials can be wrapped around a sharp corner of an article, building, etc.
