UVC disinfection of food packaging materials and surfaces by log stages

Harmful germs such as bacteria, yeasts and fungi need to be completely removed during food packaging. UVC disinfection is a dry and chemical-free method that reduces the germ load by 99.9% (germ reduction rate log stage 3).

UVC disinfection of films

Just a few seconds of the intense UV light are sufficient to render harmless food spoiling germs such as bacteria, yeasts or fungi on sealing foils and yogurt cups.

To efficiently inactivate even the more UVC-resistant mold fungi, it is recommended to use UVC radiation following disinfection with low-percentage hydrogen peroxide (1% to 3%).

This combination uses two mechanisms: the UVC radiation inactivates microorganisms which are less sensitive to hydrogen peroxide, e.g. bacillus subtilis spores, and hydrogen peroxide destroys microorganisms that require a high UVC dose, e.g. aspergillus niger spores.

This achieves an efficient and broad germicidal effect and a reduction of the germ load by up to 99.99% to provide the required germ reduction rate of log stage 4, "Ultra-clean".

This means a longer shelf-life and less returns of spoiled food.

Your advantages using UVC disinfection

  • Dry and cold disinfection
  • Energy-efficient
  • No chemicals
  • Just low heating of the packaging material
  • UVC disinfection in-line with the filling and sealing machines
  • Easy shielding of the UVC radiation e.g. by means of Makrolon® panes
  • Safe method due to breakage detector
  • Easy retrofitting due to compact versions
  • Long service life
  • UVC light ensures more hygiene during the cold filling of paste-like and liquid foods
