The food packaging sector is undergoing its fastest technological evolution in 30 years. Collaborative robots, artificial intelligence, sustainable films and industrial connectivity are reshaping production lines. Here are the trends that will drive investment over the next two years.
Collaborative robots (cobots) in packaging
Cobots (collaborative robots) are replacing operators in loading-unloading, portioning and machine feeding operations. Unlike traditional industrial robots, they work side by side with humans without safety barriers. The cost of a cobot for vacuum chamber loading has dropped below €35,000, with ROI in 12-18 months in medium-to-high labour cost contexts.
- Cobot for chamber feeding: simple integration, 12-18 month payback
- Machine vision: product recognition and automatic positioning
- Pick-and-place: portioning and tray sealer feeding at 60+ pcs/min
- Flexibility: reconfigurable in < 30 min for different products
Industry 4.0 and OPC-UA connectivity
Connected machines transmit real-time production data (output, waste, process parameters) to the MES or company ERP. The OPC-UA protocol is the emerging standard for interoperability between machines from different manufacturers. This enables predictive maintenance, AI-driven parameter optimisation and complete traceability of every pack.
- OPC-UA: standard protocol for machine-MES communication
- Real-time dashboard: OEE, output, waste, alarms
- Predictive maintenance: pump vibration analysis, bar wear
- Digital traceability: every pack linked to process parameters
Sustainability and new packaging materials
The EU Packaging Regulation (PPWR) being approved will impose increasing shares of recycled material and mono-material recyclability by 2030. Machines will need to handle mono-material PP or PE films that present different sealing challenges compared to traditional multilayer films. Machine manufacturers are developing sealing bars and temperature control systems specific to these materials.
- Mono-material films (PP, PE): recyclable but harder to seal
- Bio-based films: PLA, PHA — shelf life and barrier compatibility challenges
- PPWR regulation: recyclability obligation by 2030 for all packaging
- EMA Pack: software updates and sealing bars for new materials
