Automotive rials 10 Years ago „Green“ packaging for electronic components Article contributed by Thomas Weigl, Managing Director, Sukano Products Ltd., Schindellegi, Switzerland E Transparent antistatic masterbatch for PLA ven electronic components can be attractively packaged in compostable plastic - at least they can if Sukano‘s transparent antistatic PLA (polylactic acid) masterbatch is used. The highly transparent materials compare well, both technically and economically, with conventional alternatives, and have the added advantage of being biodegradable. And to be sure that the product in the pack is not only presented in an environmentally friendly and attractive way, but also securely protected, Sukano calls once again on its experienced research team: SUKANO ® PLA as S546 transparent antstatic masterbatch significantly reduces the surface electrical resistance and so prevents the build-up of a static charge on film, sheet and injection-moulded parts. The packaging attracts less dust and the risk of damage to any sensitive components by electrical discharge is extremely small. On PLA film extruded in the Sukano test laboratory using 4 to 6% (monofilm) and also 5 to 7% (outer layer of laminated film) of SUKANO ® PLA as S546 and 2% SUKANO ® PLA dc S511 slip/antiblock masterbatch, a surface resistance of █1011 ohms was measured and any electrostatic charge was dissipated after a few seconds. In order that plastics processors can achieve optimum performance for each application Sukano offers, in addition to the antistatic masterbatch, a wide range of functional and visually enhancing masterbatches and compounds. These include the recently launched and highly successful SUKANO ® PLA im S550 impact modifier, plus slip/antiblock, UV and color masterbatches, to mention just a few. All SUKANO ® PLA masterbatches are biodegradable and the majority of them are approved for food contact. They can also be supplied by the manufacturer in combination, i.e. as special tailor-made masterbatches to provide processors with an ideal performance profile. Published in bioplastics MAGAZINE In May 2018, Daniel Ganz, Global R&D product leader for Bioplastics masterbatches at Sukano says: Sukano is proud to have embarked in the bioplastic challenging journey already since 2005, and witness the progress over the years of our bioplastics portfolio. Back 10 years ago, Sukano was promoting its PLA transparent impact modifier, and its antistatic masterbatches for PLA electronics packaging, launched around the same period, which now became a reference in the market. Since then, Sukano´s portfolio has grown significantly with the market and its demand, from a product range for any kind of polylactic acid (PLA), as well as polybutene succinate (PBS) and bio PET. From these days till today, the company has defined its bioplastics platform of masterbatches as core and strategic, established presence and proactive engagement and collaboration with leading companies in the bioplastics supply chain for the full PLA and PBS bioplastics market (cf. p. 18). This decision has proven to be successful both in generating industry-leading technical know-how about bioplastics processing for our technical experts and dedicated R&D team, resulting in new products brought to the market. Companies can now use our masterbatches certain that the integrity of their claims, certifications on compostability and biodegradability will be supported by our products. Just as well as mechanical and visual properties will be very close to conventional oil-based plastics allowing manufacturers to use bio-materials that meet all their processing requirements and which can be adapted to each packaging and production practices. Such as for BOPLA, creating lighter weight packages with a greater proportion of biobased content. Or the launch of new PBS-based masterbatches for flexible packaging manufacturers to design new multi-layer packaging structures – addressing the consumer demand for lower environmental impact through smart product design and packaging. And we are extremely active in this field, aiming to continue to bring the bioplastics applications to more diverse markets and processing conditions. 30 bioplastics MAGAZINE [03/08] Vol. 3 bioplastics MAGAZINE [03/18] Vol. 13 51
