The antibacterial film market is growing rapidly day by day as antibacterial films are applied to various places where cross-infection can occur due to the spreading of COVID-19. However, antiviral films that deactivate the virus 99.99% within 24 hours according to the test standards are not yet available in the market. Also, there are no film manufacturing companies worldwide that have a test report for 99.99% deactivation of COVID-19. Currently, all antiviral film manufacturers' reports, including copper ion antibacterial films and silver nanobacterial films, are only 24 hours of sterilization reports for general pathogens, and none of the manufacturers still have more than 99.99% reports on COVID-19. Will copper or silver antiviral films distributed on the market be effective in killing the COVID-19 virus? LiSTER K-viro antiviral film is made of Eco-froiendly Bio nano materials. And, LiSTER K-viro completely kills and blocks COVID-19(SARS-CoV2), Influenza, Coaxkievirus and Herpes virus. The test reports issued by KR Biotech, BSL3 grade disease control laboratory, show the efficacy of the LiSTER K-viro film. [ Specifications ] 1. Adhesive antiviral film a. Material : PET b.
