A green shrink film for packaging frozen food, fruit and vegetables that can oxobiodegrade has performance at par with conventional films has been introduced by French packaging company Bollore. The Bolphane Byo film oxidizes with the effect of light and heat, disintegrating into components that are bio-assimilated by soil microorganisms, leaving only water, carbon dioxide and biomass, whether in normal landfill conditions or when accidentally abandoned in nature. The shrink film meets the EU food contact standard and internal tests have proved its oxobiodegradability, though it still remains recyclable. The polyolefin film will completely disappear within three years, unlike the 300 years taken by conventional shrink films.
The film is based on its BY grade of polyolefin shrink films, whose unique five-layered construction makes sealing easier and also provides exceptional clarity and gloss. It offers mechanical and esthetical characteristics equivalent to that of other high performance shrink films- outstanding yield, excellent sealing, hot slip property after shrinkage and good optics. It also seals and shrinks at considerably lower temperatures than any shrink film currently available, thus offering additional environmental benefits. The film has good machinability on high speed shrink wrapping equipment and can also be run effectively on manual machines.
