Seedling label for compostable Jungbunzlauer polymer additive

With CITROFOL® BII, Jungbunzlauer is now offering a certified compostable citrate ester – a known substitute for phthalate plasticiser in many applications.

Every year more than 600 billion plastic bags are produced – and there is hardly anyone in the world who does not use them. The bulk of these plastic bags end up somewhere in nature and, depending on the materials they are made of, the degradation process takes between 100 and 500 years. Thus, many governments have forbidden or restricted the use of plastic bags, while others have imposed high taxes on them, making them a luxury good. The industry, however, has come up with alternatives. The modern, green bioplastics are made from renewable sources, which in most cases require plasticisers to achieve comparable properties in terms of stability and flexibility to nowadays bags.

The additives used in these bio-based plastics also need to be fully biodegradable. There are standard requirements for these additives, and many manufacturers ask for additional certifications.

CITROFOL® BII, a versatile, first-rate plasticiser, has been certified by the renowned DIN CERTCO institute according to the US standard ASTM 6400 and the European compostable additives standard DIN EN13432.

Biopolymers with CITROFOL® BII will fully decompose without influencing soil. Consequently, the additive was granted permission to use the well-known seedling label, which indicates a voluntary self-commitment to environmentally friendly products and has been acknowledged by the European authorities.

Compostable plasticiser for a regenerative future

CITROFOL® BII is a citrate ester suitable for traditional polymeric products and bio-based plastics, which now bears the seedling symbol for sustainability.
