Sirane Sira-Flex Resolve wrapping film

Shelf-life extension of between two and five days has been reported for fruit and vegetables using Sirane’s Sira-Flex Resolve wrapping film. Retail trials using the film have reported four additional days of shelf life for potatoes and similar results with other fruit and vegetables.

Sira-Flex Resolve has been developed to have the optimum balance between humidity control and O₂ and CO₂ permeability. The permeability is temperature dependent so that the ideal atmosphere is maintained inside the pack even if the storage temperature is variable. There is no condensation on the inside of the film and the product does not dry out. As there will be no ‘fogging’, mould or bacterial growth will be minimised.

The film is suitable for all types of vegetables including salads as well as many types of fresh fruit. It is a natural biopolymer made from plants and is sustainable and fully compostable. The permeability is controlled by the property of the film itself.

Due to the structure of the film material, the permeability to humidity, O₂ and CO₂ is different in each case. This has allowed Sirane’s team of scientists to balance the permeability of each component to achieve the optimum result.
