The demand for biodegradable and compostable plastics is growing significantly due to the stricter environmental regulations and the rising consumer awareness. Consequently, a higher usage of biodegradable polymers has been recommended by various organizations. In order to increase the acceptance of these materials, color plays a significant role.
Heubach has been working on developing innovative colorants which appeal to customers while at the same time do not affect biodegradation and compostability.
Coloration of Biodegradable Polymers
The coloration of biodegradable polymers – such as PLA, PHA/PBS and PBAT – requires a careful selection of pigments that must comply with strict environmental standards. Our range of organic pigments complies with EN 13432 when not used above the maximum concentration in the final plastic application.
OK compost Certification
Selected products of our PV Fast and Graphtol ranges now feature the OK compost INDUSTRIAL label which guarantees that packaging and products are compostable in an industrial composting plant, fully meeting the requirements of the harmonized European Union EN 13432:2000 standard, and compliant with the requirements of the EU Packaging Directive.
