Toppan develops film-type Virusweeper™ packaging with antiviral and antibacterial functions

Toppan Printing, a global leader in communication, security, packaging, décor materials and electronics solutions, has developed film-type Virusweeper™ packaging with antiviral and antibacterial functions.

The new film packaging is an addition to Toppan’s "SMART LIFE-VALUE™ Packaging” lineup, part of the recently launched "TOPPAN S-VALUE™ Packaging” range targeting added value for society and fulfilling living. Samples of Virusweeper™ film packaging will be available from March, with the launch of sales scheduled for April.

The COVID-19 pandemic has prompted an increase in safety and hygiene awareness among consumers and propelled demand for contactless environments and products offering antiviral action. In response to these needs, Toppan took advantage of its unique printing and coating expertise to first add antiviral functionality to printed décor materials. Toppan subsequently applied the treatment technique to packaging, announcing Japan’s first paper-based carton packaging capable of reducing the presence of virus particles on surfaces in October last year. Toppan has now enhanced the lineup of the Virusweeper™ series by establishing technology for adding both antiviral and antibacterial performance to film packaging.

Virusweeper™ packaging inhibits the growth of certain viruses and bacteria and significantly reduces their numbers on surfaces. The action of both the film and carton types of Virusweeper™ has been verified by measurement in line with ISO 21702 for antiviral activity and ISO 22196 for antibacterial activity on plastics and non-porous surfaces, and the packaging has been certified by Japan’s Society of International sustaining growth for Antimicrobial Articles (SIAA) for its antiviral and antibacterial performance. The packaging also conforms to Japan’s specifications and standards for foods and food additives.
