Die-cuttable and printable adhesive containing labelstocks for use in preparing die cut adhesive labels, and methods of preparing the labelstocks and die cut labels are described. The labelstocks comprise extruded machine direction oriented monolayer or multilayer films and an adhesive layer. The monolayer films comprise a mixture of about 25 percent to 80 percent by weight of a propylene polymer or copolymer, and from about 20 percent to about 75 percent by weight of a polyethylene. The films are stretch oriented in the machine direction at a temperature at about or above the melting temperature of the polyethylenes.

A method for recycling materials having an affixed label is disclosed. The present invention also includes labels and adhesives that is readily removable from a material during a process for recycling the material.

Disclosed are articles having authentication features, as well as methods for authenticating such articles by forming authentication features to prevent or diminish counterfeiting activities. A surface of an article to be authenticated (or a surface of a component associated with the article) may have a region with a periodic array of nanopillars comprising a polymeric material formed thereon. The array of nanopillars thus defines an authentication feature (e.g., a graphic image or other pattern). In certain aspects, the authentication feature may be substantially invisible to the human eye under normal conditions, but revealed when condensate is created on the surface by exposure to moisture or vapor (e.g., human breath). The methods of forming nanopillar arrays disclosed herein are simple and permit single-step replication with high fidelity. Furthermore, the methods may be used with a variety of substrates, including fabric, textiles, leather, glass, paper, and metals by way of non-limiting example.

The invention relates to a shrink multilayer face film and a label produced thereof. According to an embodiment the multilayer face film comprises a core layer including: propylene random copolymer(s) or propylene terpolymer(s); and polyolefin elastomer(s), polyolefin plastomer(s), or olefin block copolymer(s); and a first skin layer and a second skin layer comprising at least 80 wt. % of cyclic polymer(s). The invention further relates to a method for providing a shrink multilayer face film and a method for labelling of an item.

A method for marking an item including a shape memory polymer (SMP) having a visual readable and/or machine readable graphic element on the surface of the item. The method includes pretreating the surface of the item; coloring the surface of the item with a dye solution containing an organic dye and an organic solvent; cleaning and drying the surface of the item; and engraving by at least partially ablating the surface of the item. The dyeing process is suitable for coloring the surface of a shape memory polymer (SMP), wherein the information is engraved in a form of a code or other label on the colored surface. The coloring causes an increased contrast and thus facilitates machine readability of marking and coding without affecting the other properties of the SMP.

What is provided is a heat-shrinkable film and a heat-shrinkable label that, when applied to a container in which the difference between the diameter of the body portion and the diameter of the mouth portion is large, sufficiently shrink in the mouth portion and do not easily allow the generation of a wrinkle or a sink mark in the mouth portion. The heat-shrinkable film contains polyester, a dicarboxylic acid component that constitutes the polyester contains 95 mol % or more of terephthalic acid, and a diol component that constitutes the polyester contains 50 mol % or more of ethylene glycol and 15 mol % or more of cyclohexanedimethanol. The shrinkage rate in the primary shrinkage direction when the heat-shrinkable film is immersed in hot water at 70 C. for 30 seconds is 20% or less, the shrinkage rate in the primary shrinkage direction when the heat-shrinkable film is immersed in hot water at 80 C. for 30 seconds is 45% to 65%, and the shrinkage rate in the primary shrinkage direction when the heat-shrinkable film is immersed in hot water at 98 C. for 30 seconds is 65% or more.

A marking label includes an RFID transponder with an RFID chip and an antenna structure which are coupled to one another by signal technology, and a sealing layer which covers the RFID transponder. The sealing layer is bonded to a substrate by welding so that the RFID chip and/or the antenna structure is surrounded by a weld seam and enclosed between the sealing layer and the substrate.

Die-cuttable and printable adhesive containing labelstocks for use in preparing die cut adhesive labels, and methods of preparing the labelstocks and die cut labels are described. The labelstocks comprise extruded machine direction oriented monolayer or multilayer films and an adhesive layer. The monolayer films comprise a mixture of about 25% to 80% by weight of a propylene polymer or copolymer, and from about 20% to about 75% by weight of a polyethylene. The films are stretch oriented in the machine direction at a temperature at about or above the melting temperature of the polyethylenes.

A method and system is provided for forming a three-dimensional image and, more particularly, for making three-dimensional digital image transfer thermoformed objects on, e.g., generic molds. The system comprises a computer infrastructure operable to receive images of a subject. display the images, stitch together the images to form a single image, adjust portions of the images or single image to compensate for deformation during thermoforming of the single image, register the single image with points on a mold, and print the single image.

A method for recycling materials having an affixed label is disclosed. The present invention also includes labels and adhesives that is readily removable from a material during a process for recycling the material.
