Application News Biobased barrier packaging for cheese Bicycle mudguards As part of a diploma project on the subject of “Ecologically sustainable packaging in the food industry” the Ecological Dairies at Allgäu (ÖMA – Ökologische Molkereien Allgäu) worked closely together with Plantic Technologies GmbH (the German branch of Australian Plantic Technologies Limited) on the basic concepts of using sustainable packaging materials. After an extensive series of product tests the cheeses specialists, who consistently focuses on ecological products, decided in February 2013 to try a new approach to the packaging question and from April used Plantic eco Plastic for the first time for their pre-packaged sliced cheese. Plantic eco Plastic was developed to replace petroleumbased plastics with bioplastics in the food industry. It is the first barrier packaging in the world that is biobased up to 80% from renewable resources. The thermoform sheet consists of a three-layer structure with the Plantic core layer being up to 80% of the total film thickness and having particularly good barrier properties, as explained to bioplastics MAGAZINE by Brendan Morris CEO at Plantic. “It is embedded between two very thin layers of polyethylene which also contributes to the excellent sealing performance of the laminate film. The new biobased lidding film will come in the next few months”. During the production process up to 50% less energy is used when compared with conventional polymers, and Plantic eco Plastic can offer this material, which is so important for food packaging, in good quantities. “That was an important step in the right direction, and underlines our company philosophy. We aim for ecological progress and high quality. In both areas, using the new packaging, we have made a significant step forward”, said Michael Welte, CEO of ÖMA. “As the first German supplier of bio-cheeses we have now developed a sustainable packaging solution for our bio-cheese slices that also supports the product’s freshness.” “At the time of the changeover we had two main problems”, continued Michael Welte. “Firstly we had to ensure that the maize-based packaging we were using was totally free of any genetically modified products, and secondly, since our product places high demands on the barrier performance of the packaging material it was important that our project partner Plantic Technologies, was able to offer a material that would not allow any loss of quality or taste”. “We were able to confirm this within the extensive product test programme that was carried out”, said Brendan Morris. MT Zéfal (Jargeau, France) is the world’s leading manufacturer of bicycle accessories. Innovation and environment play a significant part in the corporate strategy and eco-design of the products is part of a longterm progress undertaking. Zéfal launched its bio-based range Green’Z with a low carbon footprint at the Eurobike show in 2012. This range, the first in the world, comprises the Green’Z Deflector FC50 & RC50 mudguards made with plant-based plastic. To this end Zéfal selected Gaïalène ® (by Roquette) on account of its certified environmental qualities and its possible recyclability at the end of life. This plastic has turned out to be easy to use with slight manufacturing process adjustments and has enabled a reduction in the consumption of electricity used by the injection machines. ‘’Focused on the future our teams who are passionate about their work innovate every day in order to improve the practice of cycling. The strong links we have forged with the cycling community and the bicycle distributors inspired the creation of this Green’Z range”, explains Mathieu Brunet, the Chairman and Chief Executive of Zéfal. This initiative enables Zéfal to propose a range of products that constitute a breakthrough from an environmental standpoint, while retaining the same manufacturing quality that the customers are used to. The mechanical and ageing tests have confirmed the suitability of this material for these applications linked to sport and nature. The result is a carbon footprint reduced by over 65% compared with the products usually made from polypropylene, without any compromising on the technical or economic performances. Zéfal is consequently going to pursue this initiative with several products in its range and intends in the coming years to develop the Green’Z brand by innovating in other complementary applications.

Application News First PA 410 film introduced DSM Engineering Plastics (since early 2012 headquartered in Singapore) recently announced that its development partner MF Folien GmbH in Kempten, Southern Germany, successfully introduced a new polyamide film, which is based on DSM’s bio-based EcoPaXX ® polyamide 410. MF Folien is a leading expert in the production of polyamide film, and has been DSM’s development partner for EcoPaXX film from the start. In 2011, the company was the first to create samples of 30 µm cast film from EcoPaXX. This film has the same high quality level for which MF Folien is very well known in the market. Samples of film based on EcoPaXX are available in various thicknesses: 30, 40 and 50 µm. Potential application areas are in flexible food packaging, building & construction, medical, aviation and shipping. Rainer Leising, general sales manager MF Folien, said: “We are delighted to be working with DSM on the development of this innovative and sustainable material solution. Since we first introduced EcoPaXX film, with its distinctive shiny, silvery ‘high-tech’ appearance, the material has been featured in our product brochure.” EcoPaXX polyamide 410 films are strong and transparent with a high puncture resistance. They have a reduced moisture transmission rate versus polyamide 6 film, and a comparable oxygen barrier. When fully wet, the oxygen barrier of polyamide 410 is even higher. Recently, three grades of EcoPaXX were given the “Certified Biobased Product” label (70%), awarded by the United States Department of Agriculture (USDA). The bio based content of EcoPaXX polyamide 410 stems from one of its building blocks, derived from castor oil obtained from plants that grow in tropical regions and which are not used for food products. MT PLA serviceware in Asia Purac’s partners have successfully launched a range of PLA serviceware based on PURALACT ® Lactides. The range, available in retail outlets in Singapore, features printed text ‘Love Eco’ and ‘PLA’ on each item. The packaging includes a variety of sustainability and performance statements, including: • dishwasher safe • microwave safe • food contact approved (USA & Europe) • biodegradable. The serviceware is being produced by New Sunrise Plastics Co and is retailed at Giant Hypermarket in Singapore. Puralact Lactide monomers for PLA are exclusively made from non-GMO feedstocks, heat resistant up to 120°C, biobased, biodegradable & recyclable. bioplastics MAGAZINE [03/13] Vol. 8 35
