Brazil’s got a brand new antimicrobial, biodegradable bag

Symphony Environmental Technology Laboratories announced that its d2p masterbatch incorporated in polyolefin films exhibits antiviral performance of 99.9% after two hours and 99.999% after 24 hours. The tests were conducted at the Institute of Biology at Unicamp University in Sao Paolo, Brazil, according to ISO 21702:2019, EN 14476:2013, and Robert Koch Institute standards. It was demonstrated that the active compound was active toward the virus only and would not harm host cells, said Symphony. Moreover, d2p technology is embedded in the plastic and provides protection for the lifetime of the product, said Symphony.

“This is another important breakthrough for Symphony that leads to an exciting commercial phase that will help accelerate our global sales pipeline for d2p already in development,” said CEO Michael Laurier. “Plastic is the only material in common use that can be given anti-microbial properties, and d2p can be included in almost all the plastic products that we touch every day.”

Indeed, shortly after this announcement on Sept. 14, the Brazilian chain of supermarkets Cotripal launched its biodgredable d2w and antimicrobial d2p carrier bags. Symphony is the technology partner of the program and RES Brazil masterbatch supplier is the exclusive distributor.

Cotripal is the world’s first supermarket to upgrade its carrier bags by using antimicrobial and biodegradable plastic technologies together, said Symphony, thus giving consumers additional protection they most urgently need from coronavirus and other harmful bacteria. The addition of d2p also makes it safer to re-use the bags. The addition of  d2w biodegradable technology goes further, by protecting the environment from any plastic that escapes on land or into the oceans, said Symphony.
