Modern food and beverage packaging requires reliable product identification and monitoring across complex supply chains, where temperature variations, moisture, and metallic surfaces pose significant technical challenges. Current RFID implementations face interference issues with metal containers, signal degradation in high-moisture environments, and reliability concerns during microwave heating—where field strengths can exceed 1000 V/m.

The core challenge lies in developing RFID systems that maintain consistent performance across varying environmental conditions while meeting food safety requirements and remaining cost-effective for mass production.

This page brings together solutions from recent research—including electromagnetic shielding structures for microwave-safe tags, conductive packaging designs that enable frequency transformation, smart containers with integrated temperature monitoring, and specialized RFID modules for metal surfaces. These and other approaches focus on practical implementations that enhance supply chain visibility while ensuring product safety and quality.

1. Conductive Packaging-Based Frequency Transformation for Dual-Frequency RFID Communication

TETRA LAVAL HOLDINGS & FINANCE S A, TETRA LAVAL HOLDINGS & FINANCE SA, 2024

Method for wireless information exchange between a user device and a food package holding a liquid food product using the conductive properties of the packaging material and/or the product to transform frequencies. The food package has an unshielded RFID device operating at a lower frequency. When the user device with a higher frequency RFID device is nearby, it activates the lower frequency device via electromagnetic fields. The user device transmits a request at the higher frequency which is transformed by the package's conductivity into the lower frequency for the package device to respond. This allows exchanging info between devices using different RFID frequencies leveraging the package's conductive properties.

2. Container Incorporating Slit-Structured Metal Film for RFID Antenna Integration

MURATA MANUFACTURING CO LTD, 2023

Container with an integrated RFID module that allows RFID tagging on metal containers without interference. The container has an RFID module with a base material, metal film, and slits. The metal film on the base forms an antenna. The RFID module has electrodes connected to filter circuits. Slits separate the metal film into regions. In assembled container state, the regions capacitively connect through the container walls. This allows antenna operation despite the metal. The slit regions prevent shorting when metal film covers the container.

3. RFID Tag with Conductive Shielding Structures and Dielectric Layers for Microwave Frequency Voltage Limitation

AVERY DENNISON RETAIL INFORMATION SERVICES LLC, 2023

RFID tags for microwavable food packaging that can be safely microwaved without risk of arcing or fire.
