Application AutomotiveNews Ecological packaging for natural cosmetics Sulapac’s unique fully biodegradable eco-designed packaging has been selected by Finnish cosmetics company Naviter for its new Atopik range of natural cosmetic products. Both companies are based in Helsinki, Finland. Naviter is a fast-growing family-owned company that develops and produces innovative skin and hair care products. The company specialises in professional, medical and eco-friendly cosmetics as well as products for sensitive skin. Atopik All Over Balm will be the first cosmetic product to use Sulapac as its primary packaging. The Sulapac packaging material for the Naviter balm is made from several different types of renewable and fully biodegradable biopolymers from different suppliers, various fully biodegradable natural binders and ceramics in addition to wood from sustainably managed Nordic forests. In order to prevent product leakage from the package, Sulapac developed a barrier solution that allows 11 months stability of the product inside the package. The Naviter primary packaging recipe including barrier solution involves over 10 different biodegradable material types in addition to wood. For different cosmetic products such as oils, emulsions and make up Sulapac has developed several barrier solutions to allow 12 to 30 months product stability. Sulapac packages contain no microplastics and are specially designed for brands that value sustainability and ecological values. Sulapac CEO Suvi Haimi: “As a natural cosmetics manufacturer and innovator in its field, Naviter is an ideal partner for us as we share the same values and a vision of a future where cosmetics can be packaged and used without generating harmful plastic waste. Furthermore, both our companies draw inspiration from the purity of Finnish nature.” Naviter’s CEO Anni Linnavirta: “Thanks to Sulapac’s innovative and sustainable packaging, our packaging and content can now speak the same language. Sulapac packaging demonstrates our firm commitment to sustainability and eliminating microplastics, which will be important as we begin to expand into the international market.” MT www.naviter.fi | www.sulapac.com Gasoline-resistant bioplastic film for door handles Teijin Limited (Tokyo, Japan) recently announced that it has developed a formable gasoline-resistant film made of PLANEXT® bioplastic to replace chrome plating, which Honda Lock Mfg. Co., Ltd. has now adopted for nonconductive door handles integrated with smart-entry systems. Teijin developed the innovative film using a special metal-evaporation technology from a processingmanufacturer partner. Teijin is currently developing other automotive applications in addition to mass producing the film for door handles. This new film is made with Planext SN4600, an improved grade of Teijin’s Planext bioplastic, which is made from isosorbide, a bio-based chemical building block. In addition to original Planext properties such as chemical resistance, transparency and surface hardness, polymer reforming is used to give Planext SN4600 important new properties including gasoline resistance, formability, UV resistance. Teijin’s gasoline-resistant film is ideal for vehicle doors, which of course have the possibility of coming into contact with gasoline. Optimized heat resistance and filming technology enable high formability for fashioning into complicated shapes. UV protection helps to shield the base material and prevent discoloration. Vehicle door handles are increasingly being integrated with secure smart-entry systems that enable doors to be locked and unlocked by simply placing one’s hand on a handle sensor. The material surrounding the sensor, however, must be nonconductive to avoid sensor malfunctions, so conventional door handles made of electroconductive chrome plating coated on a resin base are not suitable. Plastic films made with a metal-evaporation process are nonconductive and already being used as metal substitutes for automotive exteriors, but they are not suitable for door handles because they are neither gasoline resistant nor highly formable. Teijin presented its innovative new film at 3Decotech Expo 2018 at Tokyo Big Site in mid February. MT www.teijin.com 46 bioplastics MAGAZINE [02/18] Vol. 13

Application Automotive News 100 % renewable and biodegradable pyramid teabags PG tips, owned by Unilever (Leatherhead, Surrey, UK) recently announced to move to fully biodegradable, plant based material in the UK’s favourite tea bag, PG tips, over the course of 2018. As part of an initial run, the new tea bags have been made using a new material that is 100% plant-based and 100% renewable. PG tips pyramid bags are currently made mostly with paper, with a small amount of polypropylene used to seal the tea bag, a method used widely across the industry. Unlike polypropylene the new PLA based sealing material is made from corn starch and is fully biodegradable. As PLA has very different thermal behaviour compared to polypropylene, Unilever had to work in close collaboration with their suppliers, to develop the right specifications that could meet their stringent manufacturing and quality standards. (Photo: The Guardian / Shutterstock) The aim is that all tea bags manufactured will use the new material by the end of 2018. Noel Clarke, Vice President Refreshment, Unilever: “Tea is the most consumed beverage after water in the UK 1 with 9 billion PG tips tea bags made every year and after 85 years of making PG tips, we have a great understanding on how brits love their tea. The new 100% plant based material we’re moving to is an innovation based on cutting edge science and technology and we’re all really excited that, starting from now, the PG tips that you know and love will come from 100 % plant based material from a renewable source that’s fully biodegradable.” Mike Falconer Hall, Organics Programme Manager, WRAP: “We’re keen to see the UK’s tea drinkers recycle their tea bags and it’s great to hear that PG tips is helping them to do this with the introduction of their new fully biodegradable tea bag. If you have a food waste recycling collection in your area, you can put your used tea bags in there. Alternatively, you could pop it into your home composter, however, our climate means it can take a long time to break down, so you may want to sieve out the leftover part of your tea bag and discard it or dig in with the compost.” MT www.unilever.co.uk | www.pgtips.co.uk How about going bio? For almost every conventional plastic, there is a bioplastic alternative. Our PLA masterbatches can help introduce PLA into your portfolio.
