The retailer is using NaturePlus compostable film from Amcor Flexibles and Flextrus in a bid to boost its green credentials and move closer to its sustainability goals.
Ninety per cent of Sainsbury’s organic fresh produce is available in compostable, recycled or recyclable packaging. The company says using the new film should help Sainsbury's achieve its objective to halve customer's household waste by composting.
Sainsbury’s packaging manager Stuart Lendrum said:
“Food packaging is very important to our customers and it influences their buying decisions. Amcor's NaturePlus compostable film helps us to meet our customers' needs and our sustainability goals without compromising on shelf life and seal performance requirements.”
Amcor believes it has created a “revolutionary concept”, with NaturePlus believed to be the first film that is both compostable and suited for use in wet environments.
Amcor sustainable product development manager Peter Ettridge said: “Sainsbury’s challenged us to deliver a non-genetically modified, compostable film for prepared produce. We created a revolutionary new concept which maximises both seal integrity and barrier properties.
"The new film is water resistant and can run in a wet environment at standard speeds. We are very excited about this new concept.”
The firm said improved sealing properties of the film also helps to reduce food waste as once the salad has been eaten, the pack can be added to the compost heap.
