A plastic launched by the company Promaflex, was found to be able to eliminate the virus. The company founded in 1988 specializes in producing surface protection films and adhesive tapes. The plastic which is made up of polyethylene with micro-particles of silver and silica (silver oxide), was able to eliminate 99.84% of the virus after 2 minutes.

The material was developed by the company Nanox, but it will be marketed by Promaflex. Nanox received input and financial support from the Sao Paolo Research Foundation (FAPESP). During the study, the material with and without the silver and silica particles were maintained in contact with the coronavirus, at different time intervals. A University of Sao Paolo Researcher, Lucio Freitas Junior said in a statement ‘The plastic film with the additive proved to be capable of achieving this objective in a much shorter time and the virucidal action increases with time.’

This plastic is the second product from Nanox that has silver and silica additives in it. The previous product was a reusable flexible plastic mask. The company applied the silver and silicon oxide in the threads of the mask to protect the wearer from COVID-19.

It is recommended to use the plastic for no more than 3 months. The applications for the anti-COVID-19 plastic are very wide. It can be used in elevator call buttons, touch sensitive screens, door handles etc..

Brazil is the second worst hit country in the world in terms of the number of deaths, and third in terms of the number of cases. Earlier this month, the Sao Paolo governor said that 60 million doses of the vaccine produced by China’s Sinovac Biotech and Instituto Butantan will be received to start the inoculation of 46 million people. Recently, another Brazilian state, the state of Bahia managed to secure 50 million doses of Sputnik V, the Russian vaccine.
