Application News Fancy Potato Poncho http://spudcoat.co.uk Last September, the Spanish sustainable products brand ‘EQUILICUA‘ presented an original garment made from bioplastic – 100% biodegradable and compostable (even home compostable in a backyard compost bin). It is a raincoat that comes with seeds incorporated into it that promote the disintegration of this new generation of materials made completely from bioplastic that is based on potato and corn starch (BIOTEC). The ‘plantable‘ potato poncho is the first product from the collection that the company calls ‘Fantastic Bioplastic‘, and for which Equilicua is already developing new projects based on plastic resins made from renewable resources. The idea is to work with diverse biocompatible materials for the production of future designs, going from textiles to other types of consumer goods. The company also wants to introduce these ecomaterials to the final consumer in a creative and innovative way. The slogan of the company - “Equilicua, thought-provoking products” - nicely sums up its principal objective. The so-called ‘Spudcoat’ was specially designed for excursions and outdoor activities (on foot or by bike). It is a large model made for people wearing backpacks. The space to insert any type of seeds is incorporated in the chest area. The graphic printing is done using biodegradable inks, free of solvents, so that the whole product can be absorbed into the natural environment if it is lost, or at the end of its life cycle (when it is recommended that the coat be buried to speed its breakdown). For the ethical company gift sector personalized raincoats are available as an eco-alternative for public or private institutions and businesses committed to the environment and Corporate Social Responsibility. Today, Equilicua is working on the development of new designs for distributors of the product. The potato raincoat can be purchased in Spain for example from Greenpeace and in the United Kingdom from Comp Bio Products Ltd. In China, the ecological product business Livegreen is launching the garment. Various selling points are available in European countries and the introduction to the Canadian and American markets is expected in the spring of 2010. MT PTT Mascara Packaging At Luxepack in Monaco last fall, Oekametall fom Bamberg, Germany presented a new standard mascara packaging line. It is made with renewably-sourced material DuPont Biomax® PTT1100, a high-performance packaging polymer with excellent surface gloss, chemical and scratch resistance. “By increasing the standard range with a mascara pack made of Biomax PTT1100, we are contributing to the awareness for sustainability. The resin has been the best material in terms of processability, dimensional stability and gloss for our quality standards“ says Mrs. Jasmin Hamida, Packaging Innovation Manager at Oekametall. This new standard product provides beauty packaging with luxury aesthetics and high performance while reducing the impact of the environment of the package. Because of the natural scratch resistance and gloss of Biomax PTT1100, Oekametall does not need to apply an additional solvent-based coating to ABS and SAN. It is a great example of reducing the environmental footprint with no impact on performance and aesthetics requirement of the beauty industry. DuPont Biomax PTT1100 (PolyTrimethylTerephthalate) is a polyester-type resin with up to 37% renewably-sourced content (bio-PDO based on corn or beet sugar) and a performance similar to polybutylene terephthalate (PBT) and polyethylene terephthalate (PET). It is intended for use in high-performance cosmetic packaging with a lower environmental footprint. Its attributes include a glossy surface for attractive aesthetics, excellent resistance to common personal care and cosmetic formulations, a naturally opaque to translucent appearance, good colorability, high scratch resistance and excellent environmental stress cracking resistance. Such attributes can create the potential for additional cost-savings during production, including the elimination of additional barrier layers for protection against scratches or more chemically-aggressive cosmetic formulations. This injection-moldable resin is especially suitable for use in cosmetic packaging applications including compact cases, cream jars, thin-walled perfume caps and mascara caps as presented at Luxepack.

Application News OLYMP Tests PLA Shirt and Blouse Fabrics OLYMP Bezner GmbH & Co. KG of Bietigheim-Bissingen, Germany is permanently on the look-out for innovative production processes to manufacture their up-market business shirts. The limited possibilities open to them when using thread and cloth made from cotton required the development of new alternative raw materials. Eberhard Bezner, Olymp‘s owner and CEO, is not just a highly experienced textile specialist, but an expert on innovative fabrics. By carefully studying the latest global developments in the manufacture of fabrics and textiles he came across the spunbond process for the production of PLA fibres. Now Olymp is testing the use of PLA as a fabric for shirts and blouses. Alongside advantages such as good wicking, good colour performance and high tear resistance, polylactide fibres constitute a particularly resource-friendly bioplastic. “To harvest a kg of cotton up to 20,000 litres of water are required,“ explains textile expert Herbert Ostertag, who has worked closely with Olymp for several years. Lactic acid production is significantly more environmentally friendly because water consumption is minimal and in certain circumstances renewable resources from local agriculture can be used. The test garments produced so far consist of 65 % cotton and 35 % PLA. The latter percentage could be higher and thus a shirt would be much more economical in the use of resources. “A Chinese supplier has been researching and experimenting on our behalf for some time now, looking at the possibility of using polylactide fibres, which are already used in other types of product, in garment manufacture,“ explains Marc Fritz of Olymp- Marketing. “OLYMP first made some sample shirts from polylactide material for test purposes. These were thoroughly tested in our laboratory in Bietigheim-Bissingen for washing performance, ease of care, light resistance, stretch and tear resistance and their resistance to abrasion in daily wear“. At the same time the first trials were carried out to test the performance and skin tolerance of the shirts when actually worn. Despite not yet having planned an advertising and marketing strategy the expectations are that this year the company will have 2000 shirts made to test the reaction of customers in selected department stores. MT www.olymp.com Biodegradable And Compostable Sugar Sachet A new product has joined the range of catering solutions available in Mater-Bi ® by Novamont from Italy. The biodegradable and compostable sugar sachet, born of a partnership between Novamont and Novarese Zuccheri joins the cutlery, plates and cups already available. With their personalisable print, the new sachets use paper extrusion coated with a special grade of Mater-Bi. This groundbreaking solution has the same performance characteristics of traditional packaging but, since it is biodegradable and compostable, it can be disposed of together with organic refuse meaning it is also eco-friendly. Laminates obtained with Mater-Bi extrusion coating ensure performance very similar to that of traditional plastics. They create a barrier against gasses and fats and have excellent thermal resistance making this type of laminate particularly suitable for food packaging. www.novamont.com bioplastics MAGAZINE [01/10] Vol. 5 35
