The scientists have already developed new monolayer films, are working on multilayer versions and foresee the eventual development of a range of biodegradable rigid packs. They have combined the starch molecules found in corn and potatoes with "readily available and inexpensive" palm kernel oil to form a free-flowing powder for subsequent conversion into film at AIMPLAS's labs.
Dr Fowler says the films already developed fulfil the same functions as non-renewable plastic films, and could be produced for a broadly similar cost, "given sufficient volumes".
He explains: "The technology is still being proven but on completion of our trials will be available to the producer partners in our project consortium, who include C&C Oils, Organic Farm Foods, Ibanez Extruders, Torres Plastic Film and Italgnocchi. We are also talking to an SME packaging converter interested in taking the technology forward."
