Equipment performance is one of the competitiveness factors for companies. Whether it concerns fillers, cappers, labellers or monoblocks, each stoppage can generate financial losses, delivery delays and a deterioration in product quality.
In order to prevent these issues, two approaches coexist: corrective maintenance and preventive maintenance. But which one should be favoured?
CDA helps you understand the differences, the advantages and the concrete impacts of these two strategies on your packaging machines.
Corrective maintenance: a risky solution
Corrective maintenance consists of intervening only when a breakdown occurs.
It is based on a simple logic: repair when the problem appears.
Advantages of corrective maintenance
- Low immediate cost (no planning)
- No scheduled downtime of machines
- Suitable for non-critical equipment
Major disadvantages
In an industrial environment, this approach quickly shows its limits:
- Unforeseen production stoppages
- High repair costs (emergency, parts, labour)
- Risk of chain deterioration
- Direct impact on customer deadlines
On a packaging line integrating a filler, a capper and a labeller, a breakdown on a single element can stop the entire process. For example, a breakdown on a capper immediately blocks the closing of containers,
making upstream and downstream packaging steps useless!
Preventive maintenance: anticipating to better produce
Preventive maintenance consists of intervening before the breakdown, according to a defined schedule (time, cycles or level of use). It is based on analysing the operation of equipment in order to avoid failures.
The main types of preventive maintenance
- Systematic maintenance (fixed schedule)
- Condition-based maintenance (based on the state of the machine)
- Predictive maintenance (data analysis and sensors)
Advantages of preventive maintenance
Adopting a preventive maintenance strategy presents many benefits for industrial players:
- Reduction of unplanned stoppages: anticipated interventions greatly limit breakdowns
- Improvement of productivity: lines operate more smoothly and continuously
- Stability of rates: the performance of fillers, cappers and labellers remains constant
- Controlled product quality: fewer defects, less waste
- Extension of equipment lifespan: components wear out less quickly
- Better cost control: interventions are planned and optimised
In the case of monoblocks, which group several functions into a single machine, this approach is even more strategic: a single failure can impact the entire production cycle.
Disadvantages of preventive maintenance
Despite its many advantages, preventive maintenance also presents certain
constraints:
● Higher initial cost (time, organisation, human resources)
● Need for rigorous planning
● Scheduled machine stoppages, sometimes perceived as a constraint
● Mobilisation of technical teams
However, these disadvantages are largely offset by gains in performance,
reliability and profitability.
The direct impact on productivity
Well-structured preventive maintenance makes it possible to greatly limit production stoppages. On a packaging line combining fillers, cappers and labellers, each piece of equipment being interdependent, a single failure can stop the entire process. Anticipating interventions therefore guarantees production continuity and secures performance over time.
The stability of rates is also essential for profitability. A lack of maintenance can lead to a loss of precision on fillers, defects in application on labellers or even a slowdown in capping operations.
Result: a drop in productivity, an increase in waste and degraded overall efficiency.
Finally, preventive maintenance helps to extend the lifespan of equipment.
Even robust machines require regular monitoring to limit wear, avoid costly replacements and secure industrial investment, particularly on complete solutions such as monoblocks.
Best practices to optimise your packaging machines
To fully benefit from preventive maintenance, it is recommended to implement a structured maintenance plan.
Support from experts, such as CDS teams, also makes it possible to optimise machine maintenance and extend their lifespan. Thanks to QUALIOPI-certified training, operators gain autonomy and efficiency across all packaging equipment.

FAQ: preventive and corrective maintenance.
1. What is the difference between preventive and corrective maintenance?
Corrective maintenance takes place after a breakdown, whereas preventive maintenance aims to avoid breakdowns.
2. Why is preventive maintenance essential in packaging?
Because packaging lines are built from interdependent machines: a breakdown can block the entire line.
3. Which type of machines is most concerned?
None, all machines must be taken care of. In the case of monoblocks, which group several functions on a single machine, it is all the more important to prevent maintenance.
4. Is preventive maintenance costly?
Preventive maintenance greatly reduces costs in the long term.
5. How to implement effective maintenance?
By planning interventions with our CDS experts, by offering training to your teams, and by choosing reliable equipment.
