Problem statement
Traditional laundry bleach sachets use polyethylene (PE)-coated filter paper for heat sealing, which leaves a residual plastic layer, making the packaging non-recyclable and environmentally harmful. This practice contributes to microplastic emissions and prevents full degradation of the material. Ugrinpack addressed this issue by replacing the PE coating with a natural, water-soluble dispersion coating that provides the same heat-sealability without leaving plastic residues. This innovation enables complete recyclability and degradation of the filter paper, significantly reducing environmental impact and supporting compliance with new EU packaging directives.
Main outcome
The solution is now being implemented in cooperation with Henkel. Internationally sourced filter paper is coated in Hungary with the eco-friendly substance, enabling recyclable and degradable heat-sealable packaging. This coated material is then processed into final packaging by partner companies, demonstrating seamless integration into existing systems. Benefits include reduced microplastic emissions, improved recyclability, lower energy consumption during manufacturing, and strengthened competitiveness for Ugrinpack. The innovation supports EU environmental goals, boosts sustainable practices in the packaging industry, and opens new market opportunities across Central Europe.
