Joint sorption project aims at migration from fibre
Research partners in SoLaPack (Sorption Layers for paper-based Packaging materials) include Celabor, Belgium, and COBRO, Poland. As a CORNET project, the aim is to work closely with small to medium-sized enterprises (SMEs) in the participating regions of Germany, Wallonia (Belgium) and Poland.
The objective is to develop active layers which will be applied like other coatings to recycled paper and board, and will adsorb (rather than absorb) any critical substances. "We are looking at different materials, including zeolite, silica, bentonite, alumine, clay and starch," explains project leader at Celabor Caroline Locre.
"Once coating formulations have been established, they will be tested on paper 'doped' with the critical substances.
"One part of the project includes the modification of sorption materials in order to obtain an 'ideal' material working with all critical substances," says Locre.
The final stages will also include pilot coating trials on commercial papers, studies regarding the recyclability of the coated materials and cost analyses.
Celabor says that its role will include the characterisation of the sorption materials, especially regarding BPA, the formulation of sorption layers containing zeolites and the characterisation of the sorption layer using specific migration tests. The other partners are the Papiertechnische Stiftung, Germany (co- ordinator), CERTECH, Belgium, and the Pomeranian University of Technology, Poland. The project began in May 2012 and will last for two years.
