BASF to Offer First Compostable Water-Based Adhesive Certified by GTI

Published on 2011-01-24. Author : SpecialChem

As producer of Epotal ® Eco, BASF shall forthwith be able to offer the first compostable water-based adhesive certified by the German Technical Inspection Agency TÜV. "Biologically degradable adhesives will play a decisive role in the future when it comes to developing compostable packaging materials," says Cornelis Beyers from Marketing Industrial Adhesives. Epotal Eco is particularly suitable for the production of multi-layer films for flexible packaging materials based on biodegradable plastics. Possible applications are bags for potato chips or chocolate bar wrappings.

Trend towards biodegradable packaging

There is growing demand for efficient and at the same time sustainable raw materials in the packaging industry. "In the past, we received, again and again, inquiries for biodegradable adhesives but were unable to satisfy them," confirms Merle Dardat, Product Manager at DIN Certco, a certification company of the TÜV Rhineland Group and of the German Standard Institute (Deutsches Institut für Normung e. V. / DIN). DIN Certco has now issued the registration notice for Epotal P100 Eco certifying the product as a biodegradable additive.

Feed for microorganisms

According to the European EN 13432 standard, substances are considered as fully biodegradable if at least 90 percent of the organic carbon contained in them is converted into CO2 within a testing period of no more than 180 days. The rotting test in composted earth showed that after 70 days only, 90 percent of Epotal Eco is broken down. The molecule structure of the product resembles the one of naturally occurring polymers. Microorganisms are able to convert them into carbon dioxide, water and biomass with the help of enzymes. The best results are achieved in industrial composting facilities since they offer ideal conditions for microorganisms. After the decomposition process, Epotal Eco leaves no toxic residuals und shows no negative impact on the environment.

Water-based adhesives - environmentally friendly and efficient Apart from its compostability, Epotal Eco offers all benefits of water-based adhesives, which are an environmentally friendly and efficient alternative to solvent-based and solvent-free products. They are free from toxic components and are suitable for food packaging. In addition, multi-layer films, which are produced with the help of water-based plastics, can be processed immediately. This helps the packaging industry to save time and money.
