If the virus’ microbes land on Cropper’s packaging’s surface, silver ions added to the paper prevent them from growing. Within two hours, the virus’ viability is destroyed by 99.9 percent.
Respiratory viruses can be transmitted where someone touches a contaminated surface. Cropper points to recent studies suggesting COVID-19 can remain viable on metal, glass, wood, textiles, plastic and paper surfaces from several hours to a number of days.
