The microbe-killing platform has been developed at the Italian laboratory of Netherlands-based Parx Plastics. It relies on a bio-mimicry effect, and does not employ biocides, instead it changes the material surface properties of trays to retard the growth of dangerous bacteria.
Through 2015, the partners have been working on integrating this into the expanded polystyrene (EPS) trays produced at Erze Ambalaj two production sites.
Independent tests carried out at the University of Ferrara have now shown positive results. These found that over 24 hours, the Parx Plastics technology reduces the presence of the bacteria listeria by 92.5%, salmonella by 96%, and staphylococcus aureus by 96.5%, compared to non-treated samples of the same materials.
The antimicrobial technology will offer the possibility of extending the shelf life and reducing instances of food poisoning for a wide range of foods, including meat, poultry, and fish.
Parx Plastics reports the new process is ‘very economical.’ Erze Ambalaj, which produces 15 million food trays every day, will now be offering the antimicrobial enhancement across its product line.
