Transmission Challenges
As RFID technology becomes essential for digital supply chain management, its application to liquid products has faced challenges due to the way liquids and metal packaging interfere with radio frequency transmission. To address this, Goodwin Inc. has collaborated with Phoenix Label to develop innovative RFID solutions that enhance tag readability for liquid goods, helping Walmart suppliers meet RFID compliance requirements.
The Challenge of RFID and Liquid Products
RFID has long been effective for tracking solid goods like clothing and footwear. However, when applied to liquid products, radio waves tend to be absorbed or reflected, causing significant reading issues. This problem is particularly pressing for suppliers in the automotive and household cleaning industries, where products often contain liquid chemicals.
Goodwin Inc.’s Innovative RFID Tag Solutions
To overcome these challenges, Goodwin Inc. and Phoenix Label introduced a new RFID tag featuring advanced inner-layer embedding technology. This design isolates the RFID chip and antenna from liquid interference, significantly improving read accuracy. The tag also features a multi-layer structure with perforated edges, allowing it to be attached to the front of packages without compromising functionality.
Additionally, Goodwin Inc. has implemented flexible tagging strategies, including:
Extended Labels & Hanging Tags – Placing RFID tags externally to avoid direct contact with liquid.
Top-of-Bottle Placement – Positioning the tag above the liquid level to ensure a clear signal.
Precise Filling Control – Leveraging advanced bottling technology to prevent liquid from interfering with the tag’s attachment point.
Exploring RFID-Enabled Bottle Caps
Goodwin Inc. is also testing an innovative approach by embedding RFID chips and antennas into bottle caps. This method minimizes signal interference by positioning the RFID components away from the liquid. Although still undergoing evaluation at Auburn University’s RFID Laboratory, it holds promise for future implementation.
Ensuring RFID Readability and Compliance
Quality control is integral to Goodwin Inc.’s RFID solution. The company:
Uses handheld RFID readers to verify tag readability during production.
Conducts post-bottling verification to ensure stable RFID performance.
Works closely with Walmart and other retailers to align with industry requirements.
The Future of RFID in the Liquid Products Industry
Goodwin Inc.’s pioneering work in RFID-enabled liquid product tracking is setting a new industry standard. As more retailers embrace RFID for inventory management, the company anticipates significant market growth. By continuing to innovate and collaborate with industry leaders, Goodwin Inc. is driving digital transformation in liquid product tracking.
