IN Brief:
- Canovation and CANPACK are collaborating to advance CanReseal toward pilot-scale deployment.
- The system is designed to add resealability to aluminium beverage cans while using established canning infrastructure.
- The project reflects growing demand for packaging that combines convenience, recyclability, and production-line compatibility.
Canovation and CANPACK have formalised a collaboration to move CanReseal toward commercial readiness and pilot-scale deployment.
The partnership brings together Canovation’s resealable aluminium can-end technology and CANPACK’s global manufacturing expertise in beverage cans and packaging formats. Stolle Machinery will continue to support the development through engineering, tooling, and can-making equipment work as the technology moves closer to pilot implementation.
CanReseal is designed to give aluminium beverage cans a resealable function while preserving compatibility with established can manufacturing and filling infrastructure. That production fit will determine how far the technology can move beyond late-stage development. Many packaging concepts work well in isolation before struggling with seaming, filling speeds, pressure retention, line changeovers, pack handling, secondary packaging, and cost.
The current beverage can system has survived because it is efficient. Aluminium cans are light, high-barrier, stackable, fast to fill, printable, and supported by mature recycling channels. Adding a new closure function without disturbing those advantages is a difficult engineering task, particularly for carbonated beverages and high-speed production environments.
CanReseal aims to bring resealability into that existing format rather than push brands toward a completely new container. Resealability gives beverage producers a route into portion control, portability, and open-pack product protection, functions usually associated with plastic bottles, cartons, and some aluminium bottle formats. The value is strongest if the pack remains easy to manufacture, easy to fill, and easy to recover in recycling streams.
CANPACK’s role gives the development a practical manufacturing frame. The company works across beverage cans, glass bottles, food and industrial packaging, and metal closures, giving it direct experience with the industrial constraints that new packaging systems must meet. Its involvement moves the project into the less forgiving stage where technology validation has to meet line readiness.
Packaging is increasingly being asked to carry more function without adding unnecessary operational complexity. Coding and data control are already moving deeper into food and beverage production, with 2D coding systems extending packaging’s role in traceability, verification, and product information. CanReseal operates in a different field, but it sits within the same broader shift: the pack is no longer a passive container.
For beverage manufacturers, the technical tests will be wide-ranging. Carbonated soft drinks, energy drinks, juices, functional beverages, alcoholic drinks, and still products each impose different requirements on closure performance, hygiene, shelf life, internal pressure, tamper evidence, and consumer handling. A resealable end must remain robust through filling, distribution, storage, opening, reclosing, and recycling.
The sustainability case will also depend on material discipline. Aluminium has strong recovery value, but any additional component or design complexity has to work inside current sorting and recycling systems. A resealable can that retains aluminium’s circularity advantage would be more attractive than a format that improves convenience while creating downstream recovery issues.
Line compatibility remains the central manufacturing question. Beverage plants are built around speed, reliability, and uptime. If CanReseal can be implemented without major disruption to established can-making and filling operations, it could open a useful new function for one of the industry’s most widely used formats. If it demands extensive equipment changes or slows production, adoption will be narrower.
The collaboration gives Canovation access to packaging manufacturing expertise at the point where design, tooling, process capability, and market demand have to converge. Pilot deployment will now test whether resealability can be added to aluminium cans without weakening the simplicity and efficiency that made the format dominant.
