Numerous advances in the development of antibacterial plastic were presented within the framework of the EHEDG World Congress on Hygienic Engineering & Design 2012. These plastics have bactericide properties, obtained by incorporating nanoparticles into plastic materials, which destroy or halt the growth of bacteria that are harmful to human health. These nanoparticles are integrated into the materials using injection, extrusion and coating techniques.
In vitro tests, a pilot plant and analytical tests have shown that MgO, ZnO, CaO, Ag and CuO nanoparticles can be integrated into these materials and have biocidic properties capable of destroying, counteracting and neutralising the activity of harmful bacteria such as E.coli and Listeria Monocytogenes, among others.
Antibacterial treatment is a very new process in the market, however, in spite of the high costs involved, Erum group is planning to apply it to hangers and other hospital sector products as well as to food and culinary sector packaging. All this depends on the demand and its customers’ needs.
