Scientists made films with zinc and tested how well they kill bacteria and break down over time.

A special type of film made with certain chemicals and tiny zinc particles can stop bacteria from growing, and how well it works depends on how many zinc particles are used.
This is about special plastic-like films that break down in soil. Films without tiny zinc particles lost 72% of their weight, while those with zinc particles lost only 47.5% after 120 days.
When more zinc oxide nanoparticles are added to special films, they become better at killing germs, which you can see by bigger clear rings around the film where germs can't grow.
A special film with tiny zinc particles makes it much harder for water vapor to pass through, keeping things inside much drier than if they were just in an open bottle.
Scientists tested special plastic wrap made with tiny particles on tomatoes and found it kept them fresh for a whole month, which means it could be good for keeping food fresh longer.
