K‘2013 Review Show

K‘2013 Review Show Review K’2013 - Oct. 16 - 23, 2013 At K’2013 some 218,000 trade visitors came from well over 120 countries around the world to Düsseldorf, Germany, between October 16 th and 23 rd , 2013. At the world’s biggest trade fair for plastics and rubber, held every three years, it again became clear that the K-Show remains the most important event in the rubber and plastics industry In our K-show preview we already presented a large number of the bioplastics related products and services. This review will round off our report with a couple of news items and highlights that we found in Düsseldorf. MT becausewecare Using bioplastic technology, becausewecare (Derrimut, VIC, Australia) has scientifically developed products that are made with a combination of organic plant and biodegradable components to break down into compost within weeks. In addition, they have programmes in place to educate business people and consumers worldwide about the negative impact that conventional plastics have on the environment. They also encourage Government moves to ban non-compostable bags, and support strict policies to ensure that all claims of biodegradation and compostability are substantiated. Most importantly, becausewecare endeavours to keep its costs to a minimum so that customers and end-users can be environmentally responsible at the lowest cost possible. The range of products of becausewecare includes retail checkout bags, waste bin liners, doggy bags, nappy bags, produce bags, food prep and related products, garden products, fashion bags, and the BotanicBag. Even the soy-based non-toxic inks used to print on the products will not leave any harmful residue in the process of breaking down. becausewecare can also extrude film, thermoform, injectionmould, and blow-mould articles to customers’ specifications, as well as supplying rigid and flexible packaging options. BIOTEC BIOTEC (Emmerich, Germany) presented their new film grade BIOPLAST 500 with a biobased carbon content of more than 50%, which biodegradable according to EN 13432, and home compostable (OK compost Home certified). Biodegradable bags made with Bioplast 500 are ready to meet the challenges of European waste disposal regulations that now require more than 40% biobased contents. The OK compost home certification also allows bags made of BIOPLAST to comply with waste disposal policies, which put a real focus on home composting. “We are extremely proud to announce that Bioplast 500 can be extruded down to a film thickness of 18 µm,” says Harald Schmidt CEO of Biotec. Bioplast 500 is designed for blown film extrusion used in short life packaging, multi-use bags (e.g. carrier bags and loop-handle bags), single-use bags (biowaste bags, bin liners, etc.) and agricultural film. Such film products are recyclable, printable by flexographic and offset printing without pretreatment and have a soft touch. The films can be coloured with masterbatches and are sealable (hot, RF, ultra-sonic) Texchem Texchem (Penang, Malaysia) introduced their proprietary biobased materials, which consist of thermoplastic starch derived from agricultural waste. This bio-based material (40% PP plus 60% non-edible food residues such as rice hull or palm fibre, corn residue, sugar cane residue, soy bean shell, cassava residue, kernel powder, etc.) can be thermoformed with a surface smoothness, texture and finish that brings elegance to different packaging applications whilst maintaining all the characteristics of conventional petroleum based plastic material. In addition, Texchem exhibited biobased injection moulding grades to replace conventional HIPS as well as to reduce destruction of forests to produce wood-based packaging. One of the benefits of the material is its good processability. There is no need for any additional equipment or processing in order to make products using this biobased material. 30 bioplastics MAGAZINE [06/13] Vol. 8

K‘2013 Review Solvay acetate bioplastic, manufactured using wood pulp obtained from SFI (Sustainable Forestry Initiative) certified forests. This it has a much lower CO 2 manufacturing footprint when compared to petroleum-based products. A new and amorphous engineering bioplastic, it is a non-toxic material. Together with a bio-plasticizer the biobased content of Ocalio compounds is at present 50 % (ASTM D6866). Gehr Mannheim (Germany) based GEHR has relaunched its bioplastic product line ECOGEHR. Gehr is a manufacturer of plastic sheets, rods, tubes and profiles, active in the bioplastic market since 2007. During K 2013 Gehr has shown its new sheets produced from Ecogehr PLA-LF and Ecogehr CL. PLA-LF is a blend of PLA, lignin, wood fibres and some additives. CL is a blend of cellulose and lignin. These wood-like sheets at a size of 1000 x 2000 mm and with a thickness of 2 mm, are dedicated to point of sale applications. Gehr is convinced that these sheets will be used for product displays, marketing materials and interior design elements. Besides their new products Gehr also exhibited the well-known Ecogehr PA 6.10 and Ecogehr WPC-30PP. The interest for semi-finished products based on renewable resources was again very high during the exhibition. Gehr’s Sales and Marketing director Thorsten Füßinger pointed out: “Now brand owners have, with these sheets, the possibility of presenting their ecofriendly products on eco-friendly product displays.” GreenWorks Zhejiang Huju GreenWorks Technology Co., Ltd is a hightech enterprise that mainly produces and sells products which are completely biodegradable and compostable, such as: deliware, cutlery, tableware and related products, as well as raw material granules. The resources of the raw materials for biodegradable products are several, but mainly corn and tapioca starch. They are natural and can completely biodegrade in a short time. GreenWorks claim to be leading the industry into a new era of petroleum-free bioplastics that recycle agricultural by-products and eliminate both the use of food crops and the use of petroleum in plastics. This can greatly reduce the food service and retail packaging industries reliance on materials that contribute to global warming, and help create new jobs and new opportunities for sustainable business practices at the same time. With excellent technical properties and performance, such as better mechanical and heat resistance, enhanced transparency and outstanding processability, Ocalio cellulose acetate compounds can not only replace applications made with engineering plastics such as polymethyl methacrylate (PMMA) and acrylonitrile butadiene styrene (ABS) but also polycarbonates (PC). The material is designed for use in a wide range of end-use consumer goods such as containers for cosmetics and personal care, food packaging, electronic devices, toys and mobile phones. In addition to the beneficial range and balance of mechanical properties and ease of processing, Ocalio plasticized cellulose acetate displays excellent surface aesthetics such as a high gloss, smooth and silky tactile qualities and an exceptional depth of colour, for both opaque and transparent grades. Manufactured in Europe in back-integrated and completely self-sufficient facilities, Ocalio cellulose acetate compounds will be commercially available in Q1 of 2014. Ningxia Ningxia Qinglin Shenghua Technology Co., Ltd. is a hightech enterprise specialized in nanometer sized biological based biodegradable environmental protection plastics and their preparation, as well as their technology research, plus manufacturing and sales. Products can be widely applied in industry, agriculture and other fields. The registered trademark of their products is Jia Jia Gu. The company’s products use potato, cassava, sweet potato and other natural plant starch and straw fibre nanometerfine powder as the main raw material, as well as food grade or pharmaceutical grade modified materials and additives. The company developed special technologies and uses advanced equipment. All of their biodegradable plastic products have properties Info: comparable to traditional plastics. The performance is between that of polyethylene and polypropylene. Under natural conditions, the products can be completely biodegradable with an adjustable and controlled degradation cycle. Currently the development and production of products include disposable snack-boxes, plates, bowls, knives, forks, spoons, chopsticks, water cups, coffee cups, toothpicks, toothbrushes, combs, shopping bags, and much more, including children’s toys and 3D glasses frames bioplastics MAGAZINE [06/13] Vol. 8 31
