Abstract

The invention relates to a biocidal polymer film comprising calcium oxide (CaO) nanoparticles smaller than 55 nm as a biocidal agent and a thermoplastic polymer selected from among polyethylene (PE), polypropylene (PP), polystyrene (PS), poly(lactic acid) (PLA), polyhydroxybutyrate (PHB), poly(glycolic acid) (PGA), or a mixture of two or more of same, in which the CaO nanoparticles are present at a concentration of between 3 and 10 wt.-% relative to the total weight of the film, as well as optionally comprising CaO nanoparticles modified with oleic acid.
