Toyobo one of Japan’s top makers of fibers and textiles and scale-up renewable chemicals company Avantium have partnered up to jointly develop thin films made from PEF, a 100% bio-based polyester with strong performance benefits. This material is based on Avantiums proprietary YXY technology for the production of FDCA, which has numerous potential applications as a bio-based building block for PEF as well as new chemicals and plastics. PEF can be produced from FDCA using conventional industrial production plants.
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 10x higher oxygen barrier, 2~3x 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. 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 & Co., Ltd. (Mitsui), with which Avantium ( @)announced a partnership in December 2015 (reported here by Bio-Based World News). The parties expect to offer samples for packaging tests from 2017 onwards.
Moreover, Toyobo and Avantium are jointly optimizing polymerization processes in Toyobos existing polymerization assets to produce PEF resin at commercial scale from MEG (ethylene glycol) and Avantiums bio-based chemical building block FDCA,. The parties intend to scale up PEF resin production to Toyobos 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 bio-based 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 polymers 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.
Using our flexible assets and the know-how of our employees, it is the strategy of Toyobo to stay ahead of the curve in bringing innovative products to the market, states Chikao Morishige, Senior General Manager Plastics Production Technology Operating Department at Toyobo. 100% bio-based PEF fits very well with our track record of introducing innovative materials and products to the market. Toyobo is therefore pleased to be working with Avantium and Mitsui to bring high performance PEF based packaging to customers.
In March this year Avantium announced it is in exclusive negotiations with BASF with the intention of establishing a joint venture for the production and market development of FDCA and the marketing of PEF.
