Application News Natural

Application News Natural Snacks in High Barrier Film Based in East Sussex, UK, Infinity Foods has been owned and operated as a workers’ co-operative for over 30 years and is one of the UK‘s leading wholesale distributors of organic and natural foods. They have now decided to use high barrier NatureFlex NK by Innovia Films to wrap its range of snack packs. Make it a Happy Meal Spondon, Derby (UK) based Clarifoil, a company of the Celanese Group has made millions of children very happy. The new movie series ‘Shrek’ gave Mc Donald’s the idea of packing 3D glasses into their traditional ‘Happy Meal’ boxes. The packaging design had to incorporate 3D glasses into a Happy Meal box without hindering handling in the restaurant. The lead-time was also immensely tight just 8 weeks to include design and production of some 12 million cartons. The ingenious design solution led to the packaging winning a number of awards. The designers specified the use of Clarifoil’s acetates because the requirements were exceedingly complex. The glasses were to be used by children and they had to be simple to handle, whilst being made of material that can have direct contact with food as well as offering transmittance values suitable for computer screens and printed cartons. The health and safety regulations which had to be adhered to were immense as the glasses had to gain approval as a toy. Marion Bauer, Marketing, Clarifoil comments: “At Clarifoil we listen closely to our customers and develop products that give greater options. No challenge is too big. We thrive on finding the right solution for specifiers.” The resulting packaging exceeded all expectations and even better, the 3-D lenses can also be recycled as they consist of a thin acetate film, combined with recycled paper. Now these glasses can be integrated into any type of carton, at very low cost. Clarifoil acetate is made from sustainable, GM free wood pulp from Sustainable Forestry Initiative managed forests, so that it has low impact on the environment throughout its life cycle. It is fully home compostable which is unheard of with competitive films that can only be composted as 50°C plus. It doesn’t emit any noxious or hazardous by-products and it adheres to the compostability criteria EN 13432 and ASTM D6400 as well as the OK Compost Home and US Composting Council standards. MT Kieran Gorman of Infinity, stated: “At Infinity Foods we are always looking for ways to limit our environmental impact and carbon footprint. For example, our catalogues are printed on paper from sustainable forests using no chlorine in manufacture and some of our transport fleet runs on bio-diesel. So opting for a film such as NatureFlex is a logical progression for us. Our products are available across the UK and Ireland and can be found at specialist retailers across Europe and as far a field as Asia. We are currently only packing our new snack packs in NatureFlex but are looking to start using the film across the whole range.” For the creation of the pack design, Infinity Foods collaborated with packaging consultant, Andy Skinner of Aboxhigh, who said: “Having supplied Infinity Foods for over 15 years and being fully aware of the company’s ethos on the environment, NatureFlex has filled the void we have been waiting for. NatureFlex is one of the most exciting products I have been involved in within my 35 years experience in the packaging industry. The high visual shelf appeal of the packs, coupled with sustainability and reduction in carbon footprint fulfills all the criteria that Infinity Foods require.” The resulting pack has helped to re-brand the range of handy size snack products including Organic Milk Chocolate Buttons, Organic High Energy Trail Mix and Hot Chilli Cashew Nuts. The NatureFlex NK used in this application provides the best moisture barrier of any biopolymer film currently available, it is 45µm thick and is flexo printed by Modern Packaging.

Application News Biopolastic Components in Cutting Dies Compostable School Milk Cups Austria‘s farmers have been supplying schools and Kindergardens with millions of portions of school milk since 1995 directly from their farms and thereby are significantly contributing to the nutritional health of children. A negative result of this activity and a major disadvantage to the environment is the enormous amount of plastic waste which is created, and in addition the waste of resources. The project ‘Compostable school milk cups / school milk packaging’ is currently replacing approx. 10 million of the traditional polystyrene cups (plastic cups) with their aluminium lids and plastic straw with compostable cups, lids and straws, based on renewable biodegradable and compostable materials, namely Ingeo PLA by NatureWorks This idea is to replace about 100 tonnes of polystyrene and about 20 tonnes of aluminium through renewable biodegradable and compostable materials in Austrian schools alone. The advantage is a huge reduction of usage of fossil resources - significant cost savings in disposal or composting, the positive example for the children in these schools and the cost savings for the environment due to the elimination of aluminium use and the dramatic reduction in the production of CO 2 . This Austrian initiative is currently Europe‘s most modern milk packaging idea and a role model and leader for the future of environmentally friendly packaging. MT Reported by Ewald Kapellner, BioBag Austria, Linz Austria At the special show on ‘Sustainable Production and Packaging’ within the framework of FACHPACK 2010, last fall in Nuremberg, Germany, the Heilbronn, Germany, based company Karl Marbach GmbH & Co. KG presented its green philosophy called ‘marbagreen’. This includes, among other things, the fact that Marbach, world market leader in cutting dies for the packaging industry, will switch step-by-step from plastic components for their dies to bioplastics. “Which we see as a very good thing!“, says Marketing Manager Tina Dost. The big advantage of the brand-new, biodegradable bioplastic that we use is that it is manufactured from 100% renewable raw material. Marbach cutting dies are being used for pharmaceutical packaging, packaging for cigarettes, cosmetics, food and much more. Since Fachpack 2010, Marbach has been replacing the die‘s plastic edge protectors with new ones made of a bioplastic material from Tecnaro. Further areas of application such as stabilizers for stripping tools, spring elements for pressure plates, handles for rotary tools for corrugated board die-cutting, as well as straighteners for blank separation, are also conceivable. Material tests are currently in full swing. In recent years Marbach’s customers have been more and more faced with ecological matters such as climate-neutral printing and carbon footprint issues. Consequently Marbach started to look into ecological sustainability at a very early stage in order to support their customers. The result was the first ‘green’ dieboard on the market - the Marbach greenplate. Based on the ‘marbagreen’ concept more ecologically sustainable projects followed. Replacing petrol-based plastics with resource-saving bioplastics is one of these projects. The Tecnaro material was chosen because it is obtained as by-product of paper production Testing has shown that this bioplastic material perfectly meets the company’s technical and design requirements. For Marbach, the most important aspect is resource-saving. Unlike normal plastics, no finite resources are used for the production of this bioplastic, which is obtained as by-product of paper production. This is how natural resources can be purposefully protected, “and,” says Tina Dost, “we, as a company, contribute to maintaining living conditions for future generations.”MT bioplastics MAGAZINE [01/11] Vol. 6 45
