K‘2013 Review Kafrit

K‘2013 Review Kafrit Kafrit Industries Ltd based in Negev, Israel introduced three new products. Ecocomp 420 is a biodegradable compound for twin-wall sheet applications. It is comprised of 100% renewable resources and fulfils the standards: EN 13432, ASTM D6400- 04, ISO 17088. Ecomp 420 compound is starch-based with the addition of plasticizers and biopolymers. This combination can be easily processed on conventional sheet extrusion equipment, with only minor process parameter changes, namely reduced temperature and controlled screw speed. Sheets of 4 mm (300 µm wall thickness) may be produced. They have a first class welding performance, excellent mechanical properties and good printability. Ecocomp 131 is a grade to produce tie layers for biodegradable multilayer films. Details will be subject of a more comprehensive article in one of the next issues of bioplastics MAGAZINE. Ecocomp 142 is a compostable PHA based compound for film applications. It is a soft, flexible compound designed for shopping bags and applications that can be easily processed on conventional film extrusion equipment. Ecomp 142 biodegrades quickly in a composting environment and in soil. Kuraray Kuraray Europe (Hattersheim, Germany) presented Mowiflex TC 232 C14, a partly biobased polyvinyl alcohol. Mowiflex TC 232 C14 is produced from bio-VAM (Vinyl Acetate Monomers) which is acquired from renewable raw materials (bio-ethylene). The use of Mowiflex TC 232 C14 allows the manufacture of biobased products such as water-soluble foils, packaging and fibres. The biobased portion of the material (measured using ASTM D6866 procedure 12 C/ 14 C) was determined to be 89%. Cathay Cathay Industrial Biotech has been a pioneering industrial biotechnology company with commercial-scale production since 2003. It is the world leader in the production of long chain dibasic acids used primarily for nylons, polyesters and adhesives and bio-solvents. Cathay’s leading-edge technological innovations allow the manufacturing of chemicals and fuels from renewable resources. Cathay is managed by a globally experienced team of technology, business and finance experts. Cathay Biotech’s Terryl Green Nylons are a series of polyamides based on their unique 100% biobased 1.5-pentanediamine, C-BIO N5 polyamide 56 and based on this new diamine has similar performance properties to PA 66. In addition to potentially substituting HMDA with C-BIO N5, Cathay’s five carbon diamine, offers new performance properties in certain polyamide applications due to the even/ odd carbon arrangement. Available Terryl polyamides include PA 510, 512 and copolymers. DongChen ShanDong DongChen Engineering Plastic Co. Ltd. (Shandong, China)‚ is specialized in the synthesis, modification development and sales of long carbon chain PA1212, and the synthesis of PA1012, PA612, and PA1010, PA 610 and transparent PA. Their annual capacity of long carbon chain nylon resins is 6,000 tonnes. The PA1212 developed solely and uniquely by the Technical R&D Center of the company has filled a gap of China and has been rated to meet PA11 and PA12 standards of similar foreign products in respect of performances. Lifocolor Lifocolor produces colour masterbatches and offer these under the brandname Lifocolor BIO. These masterbatches are for colouring applications made from bioplastics. By using pigments that fulfil the requirements of the standard DIN EN 13432 the customers can — provided a correct dosing — get certification as biodegradable per EN 13432. The colour pallet developed by Lifocolor comprises a multitude of colour shades, offering customers good opportunities to differentiate their products from competition in the various fields of applications for biobased as well as biodegradable plastics. Greemas Greemas is the brand of the biosourced materials from the Getac Technology Corporation (Taiwan). They focus on the research of the fundamental characteristics of biomass materials and provide green plastic solutions. Greemas includes three main product lines. These are PLA series, bio- PA (bio-nylon) series and NFRC series (natural fibre-reinforced composites). Based on the material features, Greemas can be applied in household items, furniture supplies, tableware, kitchenware, stationery, toys, baby and child products, packaging, and even automotive components and electronic products. 32 bioplastics MAGAZINE [06/13] Vol. 8

K‘2013 Review Celanese Clarifoil ® cellulose diacetate film from Celanese was among the world’s first thermoplastics. In the 1950s and 1960s it was the number one material for transparent thermoform packaging. Today, cellulose diacetate is again gaining popularity as an alternative to oil-based plastics. Clarifoil thermoform film from Celanese is produced from cellulose obtained sustainably from managed forestry plantations and without genetic modification. The outstanding clarity means the film has an excellent appearance and has good properties for thermoforming of outer packaging, containers, lids etc. The high thermal stability of the Clarifoil thermoform film means that the softening temperature is 120°C. This makes it especially attractive for packaging hot foods and beverages. Additionally, this environmentally friendly film is ideal for the storage and transport of goods in hot climates. The manufacturing process is very flexible, allowing for easy integration of other functions in the materials such as for UV blockers, tint or flame retardant additives. The film is approved for direct food contact and is, therefore, ideal for packaging organic fruits and vegetables, pastries or confectionary. Clarifoil film also reliably protects cosmetics, upscale electronics devices or other luxury goods and lends them a glamorous packaging design. Polyblend POLYBLEND GmbH, a company of the Polymer-Group, started offering highly flexible biodegradable compounds under the name BioBlend. These polymers consist of biopolymers and special additives that are being certified in accordance with DIN EN 13432 as well as ASTM D6400 by DIN CERTCO. Applications are landscape and agricultural films, garbage bags, hygiene and packaging films. BioBlend 1851 and 1852 are composed of biobased as well as fossil raw materials. BioBlend is highly suitable for printing without pre-treatment, welding and bonding. Of course, BioBlend compounds can also be coloured and the company Masterbatch Winter, part of the Polymer Group, offers appropriate masterbatches. Particular emphasis is on processability using standard converting machines. Film lines processing PE-LD or PE- LLD can be changed to BioBlend without any modifications. Due to good compatibility with polyethylene, changeover can be achieved without stopping the production process. Merely adjustments of temperature profiles might be necessary. Polyblend is in the process of developing a variety of new formulations in the bio sector and will soon offer bio-based and biodegradable formulations. Shanghai Disoxidation Shanghai Disoxidation Macromolecule Materials Co. Ltd. (DM) is a manufacturer of biodegradable starch resins and related derivatives, such as shopping bags, garbage bags, films and external packaging. The company is located in the Xiangshi Road Jin Ban Industrial Zone of Kunshan, Jiangsu Province and runs 10 Coperion dual screw extruders, with automatic feeding and packaging. DM has a capacity of 32,000 tonnes/year. Their product BSR-09 was developed for blown film application and is EN 13432/ASTM 6400 certified compostable. Editor’s note On a big show like K’2013, with more than 3000 exhibitors, it is of course inevitable to come across some black sheep. A total of 38 out of the 145 companies (more than 25%) listed in the official catalogue of K’2013 under bioplastics s did not offer any bioplastics related products or services at all. Or they offered products that we do not consider as bioplastics, such as oxo-additives or additives that claim not to be oxo, but rather enzymatic or organic additives. None of these companies was, however, able or willing to provide scientifically backed evidence for a complete biodegradation (per EN 14855) so far. We are still waiting for some of such promised evidence. MT bioplastics MAGAZINE [06/13] Vol. 8 33
