Application News

Application News Air-Cushioning Made of Bio-Film The air-cushioning system Airplus from Storopack, Metzingen, Germany, is being extended to include a bio-plastic material quality. The compostable film is designed to run on all the machines in the series, giving great variation on the types of applications it is suitable for. The filling and padding material can be used throughout all service departments, from small dispatch rooms to the automated distribution centre. The compostability of Airplus Bio Film is certified according to the European standard EN 13432. For this reason, the air cushions are marked with the seedling and the BPI compostable logo ensuring the recipient is aware of the shipping company’s ethos of sustainability. At present, this air-cushioning is available in the following sizes, 200 x 200 mm and 200 x 100 mm. It is planned to include further variants from the portfolio of PE films. The raw material is a biologically degradable plastic compound based on PLA with a co-polyester. It was developed by FKuR Kunststoff GmbH, Willich, in co-operation with the Fraunhofer Institute, Oberhausen, both Germany. As with polyethylene based films, Storopack co-extrudes the polymer during processing to produce a three-layered structure. Compared with mono-extruded films, this reduces material consumption, the elasticity is increased and the low permeability ensures that the air fill does not shrink. Introduction to the market will take place in Europe and North America. Airplus Bio Film is to be manufactured at the production sites in Wildau (Germany) and Cincinnati (USA). Storopack emphasises that it wishes to distinguish itself from suppliers marketing so-called ‘oxo-degradable’ films labeled as ‘bio’-products. These products are usually made of 100% petroleum based polyethylene. This PE is mixed with additives based on metal compounds to accelerate its degradation. According to European Bioplastics data, some of these additives are to be classified as hazardous materials according to EU law. For example, the presence of cobalt has been detected. World’s First Fully Compostable Net Bag Giró net bag made with FKuR´s Bio-Flex Giró from Badalona, Spain, launches worldwide first certified complete compostable net bag. The new net packaging system developed by Giró comprises 100 % compostable materials certified according to EN 13432 for net and label. For the knitted net itself Bio-Flex ® F 1130 and for the label Bio-Flex ® F 2110 of FKuR were selected. “The excellent mechanical properties of Bio-Flex and the easy processing were convincing factors that made us decide to use these materials from FKuR”, says Carles Llorens, responsible for Engineering at Giró. “We are sure that other innovations with these materials will follow.” Net bags are often used for fresh food & vegetable packaging. Quality factors are high elongation at break, high stretch elasticity as well as good printing and welding properties. Giró is a group of companies that provides state-of-art technology and systems for the fruit and vegetable packaging industry. Giró is currently present in more than 50 countries on the 5 continents. 28 bioplastics MAGAZINE [02/09] Vol. 4

Radiator End Tank Made with Renewably Sourced Plastics Application News The plant-derived DuPont Zytel ® 610 nylon resin that debuts on DENSO Corporation’s new automotive radiator end tank illustrates the benefits of close collaboration throughout the value chain and marks the first use of DuPont renewably sourced plastic in mechanical components exposed to the hot, chemically aggressive underhood environment. “The strategy of collaborating throughout the value chain is critical when cost effectively bringing high-value solutions to the market,” said Chris Murphy, global accounts director – DuPont Engineering Polymers. “This development truly illustrates a great way to get from today to tomorrow.” In this case, DENSO engineering and DuPont R&D embarked on development of a new material for use in a higher performance radiator end tank that meets auto manufacturers’ needs for sustainable solutions. The new material, developed jointly by DENSO and DuPont in a proprietary process, contains 40% renewable content by weight derived from the castor bean plant, and meets requirements for exceptional heat resistance, durability and road salt resistance – attributes DENSO says were difficult to deliver with many resins containing a high percentage of plant-derived ingredients. Production of the part for the global vehicle market begins this spring and DENSO has announced intentions to use the material in a wide range of products. bioplastics MAGAZINE [02/09] Vol. 4 29
