A collaborative research started 15 years ago by the Federal University of San Carlos (UFSCAR), Brazil, the University of Ham I (UJI), Spain, and Nanox finally launched in 2014 a patented plastic film with antibacterial and anti-toxicidal properties. This product focuses on the addition of silver nanoparticles inside a transparent PVC plastic film to achieve a germicidal effect.
The collaborative group says that upon encountering metallic silver, the semiconductor silica is activated and will produce an oxidizing molecule that is highly toxic to the new coronavirus. It can remove 79.9 percent of COVID-19 viruses in 3 minutes and up to 99.99 percent in 15 minutes.
The product is commonly used for packaging meat, fruits, vegetables, frozen meat and other foods, in addition to being used to stick on various contact surfaces to keep them clean and sterile.
This product with antimicrobial and virucidal properties was created in 2014, and the nanosilver particles were key,” said Alessandra Zambaldi, AlpFilm’s manager of promotion. But in this plague, we conducted more in-depth research and adjusted the product’s composition to make it antibacterial and more effective.”
In addition to AlpFilm, there are several other manufacturers in Brazil that produce this PVC plastic film, from which up to 450 tons are produced each month.
