A transparent PVC film with silver silicate nanoparticles incorporated into the material is an innovation designed to provide safer shrink-wrap packaging for food – especially for storage in refrigerators, as is common practice in domestic, commercial, and industrial environments. Silver nanoparticles are added to the plastic in order to eliminate bacteria and fungi, protecting the wrapped food. The technology was developed by Nanox, a company in the city of São Carlos, state of São Paulo, which licensed the product to another company, Alpes Indústria e Comércio de Plásticos. Alpes, based in the city of São Paulo, is already distributing the product under the name AlpFilm Protect. According to Nanox director Luiz Gustavo Simões, the product meets the requirements of Brazil’s National Health Surveillance Agency (Anvisa), as well as international regulations. Nanox was created by three Chemistry undergraduate alumni from the Federal University of São Carlos (UFSCar) who went on to obtain master’s degrees at the Chemistry Institute of São Paulo State University (Unesp), in the city of Araraquara. To develop the company and the technology, they received support from the Center for Development of Functional Materials (CDMF), a FAPESP-funded Research, Innovation and Dissemination Center (Cepid) coordinated by Professor Elson Longo. The CDMF also funded the development of AlpFilm.
