aalto university and vtt technical research centre, both from finland, developed a film which look like plastic, these include food packaging, where the material &ndash nanofibrillated cellulose film nfc can help increase the shelf life of a product. these films are manufactured by evenly coating fibril cellulose on plastic films so that the spreading and adhesion on the surface of the plastic can be controlled. this technique wouldn&rsquot require packaging companies to install completely new technologies. &lsquoin most cases, fibril cellulose films are manufactured through pressurised filtering. source httpwww.packagingint.comnewswoodbasedclearpackagingfilmunveiled.html
