More and more of our customers are asking for biopolymer coloration. Today, color masterbatches are made up almost exclusively of polymer carrier materials and corresponding colorants. AF-COLOR’s AF-Eco® product range is based on biodegradable materials. For our bio-based color and additive masterbatches, we exclusively use biodegradable and bio-based polyesters as the carrier matrix.
Various additive combinations are available in the AF-Eco® product range, all designed to meet the specific technical and color requirements of our customers. These products are suitable for use in injection moulding as well as for film, profile and sheet extrusion and thermoform applications. We can also create specific combination products and special tailor-made products following an application-support consultation.
Meeting Industry Standards
The defining standard for biodegradable materials in Europe is DIN EN 13432. Suppliers must carry out all necessary testing to meet this standard. The Vinçotte, and DIN CERTCO certification authorities have designated laboratories that carry out these tests. The content of non-biodegradable filler materials is limited to a maximum of 5 %, or 1 % by DIN EN 13432 standards for each individual filler material. The heavy-metal content is also regulated within this standard, primarily in packaging applications.
AF-ECO® - biodegradable film applications
For some time now, the retail sector has been using organic plastic bags which are biodegradable through an industrial composting process.
This process is regulated in DIN EN 13432 and awarded with a seal such as "OK compost INDUSTRIAL" by TÜV AUSTRIA Belgium. The biodegradable bio-compound used must be at least 90 % fragmented under industrial conditions after 3 months, and remaining fragments must not be larger than 2 mm. Furthermore, after 6 months, the film must be biodegraded to 90 %, while a conventional grocery bag remains unchanged for several decades or even centuries. With our AF-ECO® products we show you possibilities in color of the compostable plastic range.
