Researchers at a Russian university have developed an "edible cling film" for astronauts. Its practicality is no less than that of polymer films, but it can be eaten with food, making it easier to use and more environmentally friendly. .

Researchers extracted natural ingredients from a variety of vegetable soups and fruit jams to create this food packaging. This cling film can not only be used to store and heat a variety of foods, but also edible, and is as durable as polymer films. .

In addition to being used in space, this food packaging can also be used in extreme conditions such as the Arctic and Antarctica. The all-natural film is believed to slow down the oxidation process of the food it wraps and will also help solve waste disposal challenges. The report said that at this stage, this edible packaging is "unique" in the world.
