Why using modified atmosphere packaging technology in the food industry?

Modified atmosphere packaging aims to extend the shelf life of a foodstuff and maintain its quality. By responding to chemical, microbial or enzymatic processes. This allows the food industry to meet the expectations of today's consumers:  

  • Fresh products with a long shelf life  
  • Attractive food products (colour retention)  
  • Reduction of chemical additives (preservatives)
  • Maintaining food quality (taste and texture) 


The final result of a food packaging in modified atmosphere depends of the following factors: the gas mixture, the packaging machine, the packaging materials, the good hygiene, the temperature and the food product type.

‘’For products with a water activity greater than 0.91 the shelf-life is doubled. It can be up to five times higher for foods with lower water activity. "
