Pulsed Light: a high-performance decontamination technology for the integrity of your packaging
In modern production lines, packaging is becoming lighter, thinner and increasingly technical.
This evolution, essential to reduce environmental impact and optimize costs, also makes packaging more sensitive to decontamination treatments often chemical or thermal.
Ensuring microbiological safety while preserving packaging integrity has therefore become a major challenge for producers.
It is precisely in this context that Claranor Pulsed Light decontamination provides an effective solution.
5 technological pillars at the core of Claranor solutions
- COMPACT: Equipment designed for simple, space-efficient integration into existing or new production lines.
- CLEANTECH: Chemical-free technology with no residues, no effluents and low energy consumption.
- COST-EFFICIENT: Controlled total cost of ownership, with no chemical consumables, optimized maintenance and long equipment lifetime.
- PACK INTEGRITY: Effective decontamination while preserving the physical, functional and aesthetic integrity of the packaging.
- POWERFUL: Intense, broad-spectrum light that disrupts the DNA and RNA of microorganisms, achieving high microbiological reduction in a single flash, enabling the decontamination of cups and caps on high-speed filling lines up to 100,000 containers/hour.
What are the risks for your packaging?
Modern packaging is becoming lighter, thinner and increasingly technical. Decontamination must therefore deliver high microbiological performance without compromising packaging integrity, product quality or line efficiency.
Critical parameters include:
- cap, cup and lid geometry
- surface condition and appearance
- barrier properties
- sealing performance
- closure functionality
- lubricants and other functional surface treatments
- product taste, odour and sensory properties
Yet conventional decontamination methods can involve significant constraints.
Chemical treatments can provide effective microbiological reduction, but may require rinsing and involve chemical consumables, residues or effluents. Residues can potentially affect the product’s taste, odour or sensory profile, or interfere with functional treatments such as cap lubricants.
Thermal treatments can be effective against bacteria, but may be less suited to mould control and can expose sensitive packaging materials to heat, potentially affecting geometry, barrier properties or functional performance.
The challenge is clear: achieving high microbiological reduction with no impact on the packaging, the product or the performance of the filling line.
Why Pulsed Light protects packaging integrity
Compared with single-wavelength UV systems, Pulsed Light delivers intense broad-spectrum energy that acts directly on the DNA and RNA of moulds and bacteria such as Aspergillus brasiliensis, one of the most resistant microorganisms to eliminate in food packaging environments..
Pulsed Light effectively protects packaging integrity because it is:
Chemical-free: No chemicals, therefore no risk of residues, no interaction with packaging materials and no rinsing constraints.
Water-free: No humidification, which eliminates risks for cardboard, fibre-based or moisture-sensitive packaging and prevents any material alteration.
Non-thermal: The treatment is instantaneous and non-thermal. Even the thinnest lids do not experience shrinkage or deformation.
Pulsed Light achieves high microbiological reduction while fully preserving packaging structure.
Claranor solutions guarantee both microbiological integrity and the physical and functional integrity of packaging, securing production lines while optimizing overall performance.
Because efficient decontamination should never compromise packaging integrity.
