In the field of airline meal packaging, the accuracy of the sterilization process directly determines the food safety level. Traditional high-temperature sterilization easily leads to water loss in meals, while chemical reagent spraying has the risk of residue. The atomized hydrogen peroxide sterilization technology launched by the ply-pack R&D team atomizes food-grade hydrogen peroxide solution into 3-5 micron particles, so that it can be evenly diffused into the packaging environment. This micron-level atomized particle can not only penetrate the dead corners of the equipment, but also quickly decompose into water and oxygen after contacting microorganisms, avoiding the problem of chemical residues from the source.
"The breakthrough of this technology lies in the balance between 'dynamic inactivation' and 'environmental compatibility'." A supplier of airline meal packaging equipment commented. Traditional sterilization equipment needs to be left for 30 minutes before filling for sterilization, while the atomized hydrogen peroxide sterilization technology relies on a closed-loop sterilization system and can operate synchronously when the production line is running continuously. Its built-in humidity sensor can monitor environmental data in real time. When it detects that the airline meal packaging material is not tolerant enough to low humidity, the system automatically adjusts the concentration of atomized particles to prevent the packaging film from becoming brittle due to low humidity.
Actual measurement data from an airline meal production company showed that after adopting this technology, the microbial detection rate in the heat seal area dropped from 0.8% to zero. The operator specifically pointed out that the self-circulation design of the closed-loop sterilization system reduces the consumption of hydrogen peroxide by 40%, and the air pressure in the sterilization chamber is stably maintained at 0.5-0.8kPa, ensuring that the packaging bag will not deform in the subsequent high-altitude low-pressure environment. At present, this technology has been included in the recommended solution library of the International Air Catering Association (IFSA) and has become a new benchmark in the field of airline meal packaging.
As airlines' demand for lightweight packaging grows, ply-pack is integrating atomized hydrogen peroxide sterilization technology with biodegradable material processes. The head of R&D revealed that the new generation of equipment will introduce AI visual inspection modules to judge the sterilization effect in real time through spectral analysis, further shortening the quality control cycle. "Our goal is not only to kill microorganisms, but also to build a complete safety ecosystem from sterilization to packaging."
