An astonishing 11 days additional in-store shelf-life has been achieved in mushroom trials by an overseas customer using an innovative packaging film from Sirane - the same packaging film used for the Fresh: Shelf-Life Bags sold by Thinking-Cooking.
The mushrooms were packed in standard expanded polystyrene trays (EPS) which were then stretch-wrapped in Sira-Flex™ Resolve® film using an Omori machine - but the same results would be achievable by anyone buying mushrooms and just popping them in Fresh: Shelf-Life Bags themselves.
Jeremy Haydn-Davies, Sirane sales director, said: “This is once again further testament to the unique properties of Sira-Flex™ Resolve® and Fresh: Shelf-Life Bags and results like this keep coming in. These are the most impressive yet with mushrooms, and are tremendously exciting.
"The company in question, a large overseas customer, achieved an additional 11 days on what they had been achieving in store with their current packaging solution.
"We know Sira-Flex™ Resolve® has some remarkable properties, and we’ve had people running trials around the world, many of whom are now starting to share their results.
"Supermarket shelves are often full of discounted mushrooms, which are turning brown. Trials show Sira-Flex™ Resolve® can help retailers keep their mushrooms fresher for longer But it can also be used by customers who home who want are happy to buy the produce and then transfer it themselves into these amazing bags.
"It's not just mushrooms... transferring salads and fresh tomatoes, for example, can keep them fresher for much longer. The results are outstanding. Salads can often be utterly inedible within days of purchase, but not if you immediately transfer them into one of our bags.
"All you have to do is ensure the bag is sealed - a simple clothes peg will do the job, or tie a loose knot. So long as the bag is sealed, it will work."
Sirane’s Sira-Flex™ Resolve® - the packaging film used in Fresh: Shelf-Life Bags - is a unique film which has been developed to have the optimum balance between humidity control and O2 and CO2 permeability. It is perfect for keeping fresh produce fresher for longer.
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.
Very positive findings have also been reported in tomatoes, strawberries, green beans, salads and potatoes. Mr Haydn-Davies added: “We try to avoid making claims that Sira-Flex™ Resolve® will achieve a particular level of shelf-life, as there are so many factors at play - but we are convinced that users will be impressed by the results.
