Sirane's new wrapping film extends food shelf-life

16 April 2012


Significant shelf-life extension of between two and five days has been reported for fruit and vegetables using a new method of wrapping.

Retail trials using Sirane’s Sira-Flex Resolve have reported four additional days shelf-life with potatoes and equally significant results with other fruit and vegetables.

This new film has been developed to have the optimum balance between humidity control and O2 and CO2 permeability.

The permeability is temperature dependant so that the perfect atmosphere is maintained inside the pack even if the storage temperature is variable.

Simon Balderson, Sirane’s managing director, 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.

“Shelf life extension of several days and more is achieved for many products. The film is suitable for all types of vegetables including salads as well as many types of fresh fruit.”

The film is a natural bio-polymer made from plants. It is sustainable and fully compostable. The permeability is controlled by the property of the film itself.

Due to the unique 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.

Sirane’s European Development Centre is located at Stafford Park, Shropshire, UK
