Packaging Design Visible Time Timed Fading Capsule by Yilin Zhao Visible time is a new modification to traditional capsules, with a progress bar printed on our side of the capsule with our patented ink. As time goes by, the progress bars will become shorter and the color of the progress bar will become lighter. Only if the progress bars have come to an end, the drugs have expired. The patient can know if the drug has expired by observing the color of the progress bar. So as to avoid patients eating expired drugs.
