Antimicrobial films are commonly tested using JIS Z 2801, which measures the antimicrobial properties of plastics and other nonporous materials. This method has been adopted as an official procedure by The International Organization for Standardization (ISO), and is globally recognized for its reliability.
Our SGS test results indicate 99% antimicrobial effectiveness.
STEK antimicrobial films have not been approved by any regulatory body, and do not guarantee protection against COVID-19 and other infectious diseases. Those who use STEK products in the above context do so entirely at their own risk.
