interpack Preview Multilayer made from Bio-Flex® A 4100 CL / F 2201 CL / A 4100 CL FKuR has launched a new transparent, flexible biopolymer. Called Bio-Flex ® F 2201 CL this material contains a high amount of renewable resources and, in line with the other resins in the Bio-Flex family, can be processed easily on standard LDPE blown film lines and converting equipment. This brand new grade has a renewable resource content of approximately 60%. Its mechanical properties exhibit a high elongation and flexibility along with good puncture resistance. Consequently Bio-Flex F 2201 CL can ideally be used to adjust the properties of all the available Bio-Flex family resins. However, due to its limited sealing strength, Bio-Flex F 2201 CL should always be used as a mid-layer in a co-extruded structure. As a result of its mechanical properties it is the perfect partner for Bio-Flex ® A 4100 CL in a transparent 3-layer combination. Bio-Flex A 4100 CL is a clear but stiff material with properties comparable to PP. The combination of these two transparent grades offers superb and unmatched clarity for a biodegradable blown film available today while maintaining a very high content of renewable resource material. This is between 60 - 80% depending on the variation of polymers of the final structure. As both polymers are clear, the transparency of a 20µm film, for example, is close to 91% (light transmission figure). The toughness and high tear resistance are the result of the core Bio-Flex F 2201 CL layer and the renewable content of a 20 micron 3-layer structure with a layer ratio of 20 / 60 / 20 (%) is around 70%. Using such a structure, this film is ideal for VFFS applications. www.fkur.com 09F14 MANN+HUMMEL ProTec will present the latest, most up-todate technologies and systems in the areas of material drying, crystallization and condensate separation in the drying process. Exemplary for the new generation of stationary material drying systems, a SOMOS ® D 200 dry air dryer (air flow rate 200 m 3 /h) will be presented at Interpack. A new, powerful controller (MH 25) now controls the triggering of the dew point-constant dry air with the D-dryer. In combination with additional design innovations it leads to a significantly more flexible application of the dryers. The SOMOS D 200 dryer presented at the trade fair can be, for example, ‘expanded’ from nominally 200 m 3 /h up to 500 m 3 /h by adjustment in control technology. The systems engineering presented at interpack and proven many times for PET treatment in the meantime, is in principle also suited for the treatment of biopolymers such as PLA (polylactide) and is currently being tested in operation in pilot projects. www.mh-protec.com 09G10 Other companies exhibiting at interpack, that are involved in bioplastics but who were unfortunately unable to provide us with detailed information in time for this issue are: Mondi 9A24/B23 VTT Technical Research Centre of Finland 9C20-2 ANL Plastics 9D06 Medkonpack 9D10 Polinas Bio 9D15 Bollore 9D20 DIN Certco 9E04 Biobag International 9E06 Kaneka 9E07 Pacovis 9E15 Zhejiang Hangzhou Xinfu 9F08 Biostarch Technology Europe 9G06 Mitsubishi Chemical Europe 9G09 Wentus Kunststoff 9G15 Plantic 9G16 AGRIPLAS 9G18 Synprodo 9H11 Natureplast 9H19 Sleever International 07aB11/C30 Kisico 7.1 B02 Cromex 7.1 D07-5 Tianjin Greenbio 7.1A36 Velox 7.2A26 Dics Korecopack Company 7.2A39 Anton Debatin 10B45 Icimendue 10E85 Easypack 11F42 Zhejiang Zhongcheng 17A03 Itene EN1 / 05 36 bioplastics MAGAZINE [02/11] Vol. 6
