Edible cling film (Saran Wrap) developed

Scientists in the US have developed a clingfilm that can be eaten.

Experts at Oregon State University have come up with a wrapping that not only keeps food fresh but can also be safely eaten.

The film, which contains natural preservatives, can be fortified with vitamins and minerals, says the Daily Telegraph. Used in liquid form, it can also be sprayed on fresh foods such as fruit to keep them fresher.
