Smart packaging starts with the PET preform. We embed a laser-etched RFID antenna directly into the neck ring during injection, creating a unique digital ID that survives the 200 °C blow-moulding cycle.
Each 28 mm preform becomes a data carrier that can store origin, batch, and recycling history, readable by NFC-enabled smartphones at retail. For temperature-sensitive probiotics, we integrate a thermochromic pigment that changes colour if cold-chain breaches 8 °C, visible without opening the carton.
The same preform platform accommodates printed electronics for real-time freshness sensors, adding <$0.002 per bottle-a fraction of traditional smart-label costs.
Brand owners gain track-and-trace capability from filler to consumer, while recyclers can sort bottles by resin grade using the embedded RFID, increasing rPET purity above 98 %. This convergence of digital and physical data turns a commodity preform into a gateway for Industry 4.0 transparency.
