Packaging Robots Now Cost Less Than Labor Over Time, PMMI Says

The cost equation has flipped

For the first time, the total cost of deploying robots on packaging lines undercuts what companies pay for human labor over the equipment's working life. That assessment comes from Tom Egan, vice president of industry services at PMMI, The Association for Packaging and Processing Technologies, in a September 2025 column reported by Processing Magazine. Food, beverage, baking, snack, and consumer packaged goods operations are where the shift is most visible.

The claim matters because it moves automation from a productivity nice-to-have into a defensible line item on cost alone. For plant managers who have carried the same robot proposal through multiple budget cycles, the comparison now supports approval without requiring a strategic rationale beyond the numbers.

Why it matters

This cost crossover arrives precisely when the hardware can finally keep pace with high-speed packaging lines—a capability that didn't exist a decade ago. The timing opens automation to the tens of thousands of small and mid-sized manufacturers that have never deployed a robot, a group expected to drive most near-term growth. For procurement teams, it also means weighing new trade-offs: research shows heavy robot adopters spread purchases across more suppliers, gaining resilience but losing inventory efficiency.

Hardware finally caught up to the line

The reason Egan's argument lands now rather than in 2015 is straightforward: the robots that can match packaging line speeds are recent arrivals. Professor Mike Wilson, chief automation officer at the Manufacturing Technology Centre, traced the timeline in a January 2025 interview with Packaging Innovations. In the early 1980s, British Leyland's Cowley plant ran two robots; today the same site operates more than 1,000 building Minis.

Packaging lines were out of reach for those early hydraulic units, which were built for load rather than speed or precision. High-speed articulated arms, collaborative robots, and vision-guided systems changed the equation. Wilson points to collaborative robots—cobots—as the next wave, particularly for small and mid-sized manufacturers. Cobots require minimal guarding, install faster than caged industrial robots, and can be relocated when line configurations change. Wilson counts tens of thousands of UK SMEs with no robotic automation at all and expects that segment to supply most growth in coming years.

One caveat: most cobots today still operate independently rather than sharing tasks with humans. Genuine human-robot collaboration remains more promise than practice, according to Wilson. He also dismisses humanoid robots in manufacturing, arguing that any system designed for automation will be optimized for standard robots, eliminating the need for a humanoid's added cost and complexity.

AI-guided mobile robots target flexible lines

Two autonomous mobile robots illustrate how AI is reshaping packaging floor logistics, according to Packaging World's Matt Reynolds, writing in September 2025. ABB's Flexley Mover P603 carries 1,500 kg and uses Visual SLAM to map its surroundings without floor markers, achieving sub-centimeter positioning through onboard AI that recalculates load distribution and routing in real time. Programming happens via drag-and-drop in ABB's AMR Studio 4.0, and a Fleet Manager coordinates multiple units.

Agilox's OFL lifts 800 kg pallets and distinguishes itself with X-SWARM software: instead of a central traffic controller, each vehicle communicates peer-to-peer, sharing location, intent, and task status so the fleet reroutes and rebalances itself as conditions change. Reynolds frames this as a fit for plants that swap packaging configurations or retool lines seasonally, since there's no fixed infrastructure to remove.

These machines handle the unglamorous work of moving corrugate, pallets, totes, and kitted components between packaging stations. For plants whose layouts change more than once a year, the absence of floor markers and central controllers becomes the specification detail that matters.

The procurement effect automation models miss

A robot cell's ROI is typically modeled at the line level: hours saved, scrap avoided, throughput gained. But a June 2026 study in the China Journal of Accounting Research, analyzing A-share listed firms from 2012 to 2022, found that heavy robot adopters significantly reduced supplier concentration, spreading purchases across more vendors. The trade-off: better firm performance and supply chain resilience, but lower inventory efficiency and higher transaction costs. For procurement directors, the question is whether the automation plan and the supplier consolidation plan are working at cross purposes.

The nearest place to test Egan's cost claim against actual equipment is PACK EXPO International, which Packaging World lists at 2,600 exhibitors. The signal that would confirm Wilson's forecast is straightforward: if the small and mid-sized manufacturers that have never bought a robot start appearing as buyers rather than browsers, the cost comparison PMMI describes has reached the plants that needed it most.
