Screen-Printed Electrodes in Food Packaging: Toward Intelligent and Interactive Labels

Have you ever thrown out food because you weren’t sure if it was still fresh? Traditional packaging doesn’t give real-time insights, and that’s where innovation steps in.

Modern supply chains face microbial spoilage, oxidation, and quality degradation. Traditional packaging cannot detect biochemical or gaseous indicators critical for monitoring perishable food quality in real time.

Screen-Printed Electrodes (SPEs) are flexible, affordable electrochemical sensors that detect real-time changes in food freshness. They can sense gases, pH changes, and chemical markers like nitrates—perfect for integration into smart labels and packaging films.

SPE-enabled smart labels enable continuous freshness tracking, reducing food loss, enhancing regulatory compliance, and empowering consumers with visible, real-time quality cues based on scientific sensing principles.

At Alphaion, we design field-ready, scalable printed sensors for smart packaging. With a strong focus on sustainability and innovation, we’re helping reshape the food industry—one smart label at a time.
