Edible Clingfilm

Hungry summer picnickers will soon be able to tuck into their sandwiches, sausages and pork pies without having to take the clingfilm off first.

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