These PEF films are about 10 micrometer in thickness (one hundredth of a millimeter) and can be applied for food packaging, in electronics applications such as displays or solar panels, industrial and medical packages. Compared to standard PET-films, PEF-films have a 10 times higher oxygen barrier, 2 to 3 times higher water vapor barrier, improved mechanical strength and are fully transparent.
‘The performance benefits enable new packaging opportunities, such as transparent pouches for soups, sauces or baby foods’, Avantium claims. ‘The barrier properties extend the shelf life when packaging oxygen sensitive products like meat, fish, dairy products, or fresh pizzas, or moisture sensitive products such as cereals, cookies, crisps, personal care or medical products, and enhance the aroma barrier for packaged cheeses, fish or detergents.’
The market development of the PEF-films in Asia will be performed in collaboration with Mitsui, with which Avantium announced a partnership in December 2015. The parties expect to offer samples for packaging tests from 2017 onwards.
Moreover, Toyobo and Avantium are jointly optimizing polymerization processes in Toyobo’s existing polymerization assets to produce PEF-resin at commercial scale from MEG (ethylene glycol) and Avantium’s biobased chemical building block FDCA. The parties intend to scale up PEF-resin production to Toyobo’s commercial polymerization lines in Iwakuni, Japan.
‘I have been impressed by the innovative capability and drive of the Japanese industry’, says Tom van Aken (CEO Avantium). ‘Toyobo has state-of-the-art know-how and manufacturing capability in polymerization and thin films. The outstanding performance of PEF offers the potential of replacing complex and petroleum based multilayer packaging solutions, with a biobased and recyclable PEF film, without compromising the high quality standards required by Japanese packaging market. We are proud to work with such an excellent partner to scale up PEF polymer and thin film production. These developments support our efforts, in partnership with Mitsui, to introduce 100% bio-based PEF products such as films and bottles to consumers in Asia, making PEF a commercial reality.’
