Scientists in the U.S. have developed a clingwrap that can be eaten.

Experts at Oregon State University have come up with a wrapping that keeps food fresh and can also be safely eaten.

The film, which contains natural preservatives, can be fortified with vitamins and minerals.

Used in liquid form, it can also be sprayed on fresh foods, such as fruit, to keep it fresher.

Dr. Yanyun Zhao, a food technologist at the university, said, "You can use it as a film to wrap foods, or you can use it as a spray or dip to coat foods. "And you can enrich the film or coating with extra nutrients, such as vitamin E and calcium."
