Braskem’s vinyl application engineering team supported AlpFilm in developing the formulation that gives rise to the film, maximizing the potential for protection against fungi and bacteria, and achieving virucidal function – in other words, capable of eliminating viruses. In a second step, the plastic film received the addition of silver and silica based on the technology developed and licensed by the São Paulo company Nanox with support from the FAPESP Innovative Research in Small Business Program (PIPE).
