Plastic to the Rescue of Covid and More News from Brazil

Michael Stephen, an international expert on bioplastics, shares his thoughts and opinion on important issues impacting the bioplastics industry. Today, Michael writes about Plastic to the Rescue of Covid and more news from Brazil.

Covid – Plastic to the Rescue

The entire public bus system in the city of Guarulhos, Brazil -858 vehicles in total with 400,000 regular users – will soon be protected against viruses, fungi, and bacteria with d2p anti-microbial film covering the internal surfaces

The film is being supplied by a Brazilian company Extrusa Pack who said: “We wanted to contribute in some way to tackling the pandemic, and as we already manufacture garbage bags with this important antimicrobial technology, we only needed to adjust the factory equipment to produce the protective plastic film.”

Guarulhos has become the first city in the world to use anti-microbial plastic film in its public transport system. The technology can also be used to protect water pipes and tanks, and all plastic surfaces in hospitals, restaurants, schools, airports and any other public spaces, as well as private homes. d2p antimicrobial masterbatch ( ) has been tested by Unicamp University in Brazil to be 99.9% effective within one hour of contact with the microbes.

Guarulhos is the second largest municipality in the State of São Paulo and 13th in Brazil in terms of population, with 1,379,182 inhabitants. 

More News from Brazil

One of Brazil’s supermarket chains, Cotripal, started in September 2020 to use plastic shopping bags made with d2p antimicrobial technology to protect its customers from infection, and also with d2w biodegradable technology ( in case any of the bags should escape into the open environment, where they will biodegrade much more quickly.   

Six months later, Cotripal made a customer survey, which showed that the new bags have had an excellent acceptance by their customers. They perceived greater care by the supermarket for the safety and health of everyone and for the environment. Cotripal said that this perception goes beyond customers, and includes supermarket employees and all those who come into contact with the bags.

Cotripal also said that it is pleased with its investment in the bags, as they not only protect employees, customers and everyone involved in using them, but the company can demonstrate to the whole community not only its concern, but also its effective action, in the fight against coronavirus and plastic pollution – thereby reinforcing the value of its brand.
