In order to develop more environmentally conscious products, the Paper Mate division of the Newell Rubbermaid company has selected a polyhydroxyalcanoate (PHA) material to manufacture its latest innovative product range of pens and pencils available under the trade name ‘Paper Mate Biodegradable’.
The grade that has been chosen is a Mirel™ material from Telles, a joint venture between Metabolix and Archer Daniels Midland Company (ADM) that uses proprietary technology for large-scale microbial fermentation. The aim was to produce a new product line having 60% biodegradable content. As a result, the barrel, nosecone and clip of the pens and pencils have been produced by Qingdao Changlong Stationary Co. Ltd and Hanmate Pen Co., Ltd. by using the PHA Mirel™ P1003 grade.
Manufacturing these products using the new PHA grade provides cycle time reduction compared with conventional petroleum-based components. Tests have even shown that a 20% reduction in electrical consumption in molding has been achieved compared to similar ABS- or polycarbonate (PC)-based pens.
