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.

Cross-Sectional Study

In Vitro

The study tested the exact same material mentioned in the claim and found the same numbers, showing these films really do reduce water vapor transmission.

Similar Assertions

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.

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.
