What is doorknob foil?

Doorknob foil, also known as touchpad film or door handle film, is a thin adhesive film that can be applied to doorknobs, handles, and other high-touch surfaces to protect against the spread of germs and bacteria. The film is usually transparent and can be easily removed and replaced as needed. It is commonly used in public places such as hospitals, schools, offices, and public transportation to maintain hygiene and reduce the spread of infections. The film is also popular among homeowners who want to keep their homes clean and reduce the risk of illness. Doorknob foil is usually made of durable materials such as PVC or vinyl and can be easily cleaned with disinfectants.
