Abstract: Provided herein is flexible retroreflective sheeting that includes an emboss layer having retroreflective elements, a backing layer and/or metallized layer in contact with the retroreflective elements, and an interleaf layer sandwiched between two adhesive layers. The tensile and color properties of the layers of the construction allow the sheeting to be particularly useful as a label for articles, e.g., traffic safety devices, subject to crushing or bending. Also provided are methods and articles including the provided sheeting.

Abstract: A textile RFID transponder (20) has a textile carrier substrate (19) with a flat thread structure (16). At least one electrically conductive antenna thread (17) is introduced into the flat thread structure (16) of the textile carrier substrate (19). An RFID chip module (15) with a chip-bound module antenna (11) is applied to a first side of the textile carrier substrate (19) so that the module antenna (11) is coupled inductively into a transponder antenna (18) formed by the at least one conductive antenna thread (17). At least one hot-melt adhesive yarn (12; 16a; 16b; 16c) is introduced into the flat thread structure (16) of the textile carrier substrate (19).

Abstract: Provided herein is a pressure sensitive adhesive (PSA) comprising two different acrylate polymers and a metal chelating agent to produce the PSA. The PSAs produced according to the methods described herein can be used under a broad range of working temperatures, i.e., from ?99° C. to 40° C., e.g., ?40° C. to 37° C. These PSAs demonstrate optimal tack and cohesiveness and/or resistance to warm water bath, when affixed to substrates.

Abstract: A system and method for configuring Radio Frequency Identification (RFID) read and write power levels includes an RFID module that generates RF signals, a digital step attenuator that attenuates RF signals, an antenna that transmits attenuated RF signals, and an RF shield that isolates the antenna from an RFID label supply roll. A floor read power is determined by iteratively interrogating an RFID label while decreasing the RF signal power until the label fails to respond to the interrogation. A ceiling read power is determined by iteratively interrogating the RFID label while increasing the RF signal power until multiple labels respond to the interrogation. The read power level is set between the floor read power and the ceiling read power. The write power level is determined by iteratively attempting to program the RFID module while increasing the write power from the read power level until successfully written.

Abstract: UV-LED ink composition compositions containing a matrix or binder system, one or more colorants, and one or more photo-initiators. In some embodiments, the matrix or binder system is cured using one or more UV-LED sources. In some embodiments, the matrix or binder system contains one or more materials that are polymerized, crosslinked, and/or cured upon exposure to the UV-LED source. This allows the ink composition to be free of any organic solvents. After polymerization and/or crosslinking, the ink is dry. UV-LED ink compositions can be better suited for curing black inks, improve/increase productivity due to its instant on/instant off capability, and produce little or no heat. Such compositions may have environmental benefits as well as the curing process does not produce ozone and requires less exhaust air surrounding the press.

Abstract: A label assembly includes a label print layer with enhanced tensile, tear, and/or stiffness properties. The enhanced property or properties may be achieved by including a reinforcement layer, including a reinforcement material in the adhesive layer, and/or modifying the facestock layer.

Abstract: Hot melt adhesives comprising (i) styrene butadiene copolymer, (ii) olefin block copolymer (OBC), and (iii) water white hydrogenated hydrocarbon resin are described. The adhesives exhibit high optical clarity and are relatively clear over a wide range of temperatures. The adhesives also exhibit good adhesion at cold temperatures. Also described are laminates of the adhesive with polymeric films, such as adhesive labels that can be used in labeling containers. In addition, various goods such as containers labeled using the adhesives are described.

Abstract: Modification of functional groups along a polymer backbone to render the groups activatable upon exposure to actinic radiation is described. The polymers are typically controlled architecture polymers. Also described are adhesives containing the modified architectured polymers and related methods of use.

Abstract: Microporous structures in face films are described for improving printability of the films. Also described are laminates and pressure sensitive adhesive laminates including the microporous structured face films. Various related methods are additionally described.

Abstract: RFID devices are provided for improving the performance of electronic surveillance article systems. The RFID devices may be modified in any of a number of ways to decrease their peak sensitivity and increase their bandwidth, thereby stabilizing their read range. The performance of an RFID device will depend on the nature of the article to which it is associated, such that the nature of the article to which the RFID device is to be associated may be factored into the design of the RFID device to equalize the performance at an operating frequency of RFID devices associated with different articles. By reducing the peak sensitivity and increasing the bandwidth of RFID devices in an electronic article surveillance system, the size of a transition zone between two read zones of the system may be reduced.
