New film offers 'significant' shelf-life extension
Retail trials using Sirane's Sira-Flex Resolve have reported four additional days' shelf-life with potatoes and significant results with other fruit and vegetables.

Simon Balderson, Sirane's md, said: "The results are remarkable. There is no condensation on the inside of the film and the product does not dry out. The package atmosphere is maintained with the optimum balance of atmospheric gases to prevent degradation. In simple terms: the food lasts longer."

The film is a bio-polymer made from plants, which is said to be sustainable and fully compostable. The permeability is controlled by the property of the film itself.

"The key to shelf-life is to find a material that balances the oxygen and carbon dioxide permeability and the moisture vapour humidity to optimise the environment in the pack to give the maximum shelf-life. This is a difficult balance,"​ said Balderson.

"Up to now, no-one has been able to achieve this balance with complete success. Sirane has now managed it, and we think the food industry will be as excited as we are."
