Avery Dennison's New Tags Target Challenging Use Cases
The company has released seven EPC Gen 2 UHF inlays and labels for use in hard-to-read environments, such as on metal or near liquids, as well as for applications requiring durable or small tags.
May 07, 2013—
Leveraging its own research and development, as well as the improved functionality found in three different RFID chips, Avery Dennison's Retail Branding and Information Services (RBIS) division has released a new group of passive EPC Gen 2 ultrahigh-frequency (UHF) RFID tags and labels. The new offerings are intended to address use cases traditionally inhospitable to radio frequency identification, including the tagging of fragrances, jewelry, cosmetics, accessories and housewares. The company's new products include a label for tagging items containing metal and liquids, faster encoding tags with greater read sensitivity, and ruggedized tags for use in sewn-in garment applications, as well as within harsh environments.
The AD-451m5 RFID label is intended for tagging items composed of metal and liquid. Mark Hill, Avery Dennison RBIS' VP and general manager of global innovation and solutions development, says his firm's apparel customers had indicated that, based on their success in tracking women's intimate apparel and other products, they would like to track high-value items, such as cosmetics and perfumes, that can be challenging for RFID. When it comes to certain goods, such as cosmetics, lotions, fragrances, housewares and any product packaged in foil, he explains, EPC Gen 2 passive tags often have limited read range and reliability.
The AD-451m5, however, operates well in the presence of metals and liquids, Hill reports. The label is produced through a unique manufacturing process developed by Avery Dennison, consisting of using an RFID inlay (made with an Impinj Monza 5 IC) attached to a thin layer of foam twice the width of the inlay, and capable of being printed on a standard thermal-transfer printer. Once the label is printed, a liner can be removed, thereby exposing an adhesive coating. The label is then folded in half (like a hot dog bun) and the two halves adhere together, resulting in the inlay being on top of the label, with two layers of foam beneath it. Another liner, attached to the bottom-most foam layer, can then be removed, exposing an adhesive coating that is then used to affix the label to an item, such as a packaged cosmetics product.
In addition, Avery Dennison has announced the AD-318m5 tag, which is also made with a Monza 5 IC and is designed for tagging products containing metal or liquid. The AD-318m5 is small—the antenna measures 1.63 inches by 0.63 inch (41.4 millimeters by 16 millimeters)—and is intended for items on which the space available to attach a tag is limited. These include jewelry, pharmaceutical containers and intimate apparel.
The AD-234eM, AD-382eM and AD-319eM inlays are of three different sizes—the antennas' dimensions are 2.756 inches by 0.571 inch (70 millimeters by 14.5 millimeters), 1.181 inches by 1.969 inches (30 millimeters by 50 millimeters) and 1.063 inches by 0.63 inch (41.4 millimeters by 16 millimeters), respectively—and are designed for RFID applications requiring greater durability for sewing into a garment, or for high-impact situations, including automotive and industrial applications. The inlays are made with EM Microelectronic's EM 4124 IC, which can sustain greater manhandling than most chips.
