interpack Review VTT VTT

interpack Review VTT VTT Technical Research Centre of Finland, based in Espoo is a globally networked multitechnological contract research organization. Concerning bio-based and biodegradable plastics, in Düsseldorf VTT showed some examples of their developments. One example are biobased barriers and hybrid materials with improved oxygen, water vapour and grease barrier properties for packaging applications.Very thin barrier layers can be achieved with VTT’s ALD process, which stands for Atomic Layer Deposition. For print products and also for packaging applications ‘see-through’ paper and cardboard was developed. A last example in this field of applications are bio-based adhesives. Different grades can be applied as hydrophobic hotmelt adhesives, water soluble hot melt adhesives water based dispersion adhesives based on starch / biopolymer products and more. Xinfu Under the brandname Biosafe, Zhejiang Hangzhou Xinfu Pharmaceutical Co., Ltd of Linan, P.R. China offers EN 13432 and ASTM 6400 certified fully biodegradable PBAT, PBSA (Polybutylene Succinic Adipate) and PBS resins. Biosafe can be blended with other biodegradable materials (such as PLA, PHA, PPC, etc.), starches, plant fibers and inorganic fillers to modify the properties to satisfy all kinds of manufacturing and cost requirements of biodegradable products. MedKonPack Based in Menzel Bourguiba, Tunisia, MedKonPack s.a.r.l. is a producer of flexible packaging for example plastic bags and sacks that started production in September 2010. The products are EN 13432 (OK compost) certified and are made of e.g. TPS, PLA or PBAT using Chinese technology at Tunisian labour cost. The production capacity of the final project will be 25,000 tonnes/year. Limagrain Limagrain Céréales Ingrédients (LCI) based in Ennezat, France is the manufacturer of biolice, a material made from maize flour that is 100% biodegradable and 100% compostable. The broad range of applications comprises shopping bags, garbage bags, bags for garden waste, plant pots, agricultural films, industrial films and much more. A range of products that adds value to the agricultural produce of farmers and to the vitality of the environment. biolice is manufactured from maize flour using a unique process in the bioplastics sector. Nearly ten years of research were necessary to develop specific varieties that make up Limagrain biolice products. This innovation is based on a combination of cereal fractions and biodegradable polymers. biolice is an authentic product with surprising functionalities similar to those of plastic. It has a soft and silky touch without static electricity, has excellent mechanical strength, good optical properties … and the great smell of maize, not plastic. Wentus (all photos courtesy European Bioplastics) Wentus Kunststoff GmbH of Höxter, Germany, manufacturer of flexible packaging showcased different bioplastics products. WENTERRA ® biobags and biopackaging can be used for wastebags and bin liners, for bio-packaging of flowers, herbs and salads or for fruit and vegetables. The new biobased laminates WENTOFLEX ® are made from compostable films using environmentally friendly inks and glues. The barrier properties are similar to those of standard films such as PET/PE or OPA/PE. Special multilayer barrierfilms WENTOPRO ® round off the portfolio shown in Düsseldorf. 20 bioplastics MAGAZINE [03/11] Vol. 6
