The present invention addresses the problem of providing a surface protective film that makes it possible to cut blue light and has exceptional durability. As a solution, the present invention provides a surface protective film in which at least four layers comprising a protective layer made of polyurethane, a transparent substrate film, a blue light cutting layer, and an adhesive layer are laminated in the stated order.

A label material attachable to a product, and a method of applying the label material to the product is described herein. Printed indicia, such as brand identifiers or other labeling information, are applied to the substantially transparent label material using a thermal or other suitable printer. The label material is then bonded to the product using a low heat and pressure technique to activate the adhesive. Once applied to the product, a portion of the label material bonded to the product substantially blends into the product leaving only the printed indicia readily visible to a consumer.

Various embodiments disclosed relate to a surfacing film. The surfacing film includes a base layer. The base layer includes a thermoplastic polyurethane film comprising a reaction product of a reaction mixture of a diisocyanate, a polyester polyol having a melting temperature of at least about 30° C.; and a diol chain extender. There are many reasons to use the surfacing film including easier and more cost effective manufacturing of the surfacing film by directly extruding the base layer by mixing the reaction mixture in an extruder. Another reason to use the surfacing film is that the film has improved resistance to discoloration. Another reason to use the film is that the film shows good toughness.

Multilayer graphics products are described. The graphics products include a polyvinyl chloride film layer, an adhesive layer on one face of the film layer, and a polyurethane layer on another oppositely directed face of the film layer. Also described are methods of producing the multilayer graphics products.

A patch including a polyurethane film, a first adhesive layer provided on one surface of the polyurethane film, and a cover tape provided on the other surface of the polyurethane film, wherein the cover tape includes a base material and a second adhesive layer provided on one surface of the base material and an adhesive surface of the second adhesive layer is laminated on the other surface-side of the polyurethane film, and the first adhesive layer contains an adhesive and an organic liquid component.

The disclosure provides a thermal bending-free photocuring curved screen protective paster which comprises a first protective film, an OCA glue layer, a main functional layer, a PET film layer, a surface functional layer and a second protective film sequentially arranged from bottom to top. The protective paster of the disclosure can be well attached to a curved screen and the like, and avoids the phenomena of warping, forming failure, springback and the like occurring after the traditional protective film is attached. The protective paster of the disclosure has good wear resistance, good anti-scraping effect, good transparency, good temperature resistance and stable structure, which can be prepared into a film with any angle, can be firmly attached to a curved screen with a large radian, and can effectively protect the curved screen.

A pressure sensitive adhesive tape for semiconductor processing includes a base having a Young's modulus of 1000 MPa or more at 23 C., and a pressure sensitive adhesive layer provided on at least one surface of the base, and the product (N)(C) of (N) and (C) is 500 or more at 30 C., and 9000 or less at 60 C., where (N) [m] is a thickness of the pressure sensitive adhesive layer and (C) [m] is a creep amount.
