Evonik produces two BPA-alternative packaging coatings

The Dynapol range of polyesters made by Evonik has been expanded with two new products.

Dynapol L907 and Dynapol L914 have been developed as alternatives to existing coatings for  metal food cans that employ bisphenol A (BPA).

Despite official findings testifying that migration of BPA in metal cans is below safe limits, the issue remains one of concern for industry and consumers. New packages containing the material have been banned by the French government from 1 January 2015, which is helping prompt demand for substitutes

Scientists at the Germany-headquartered developer have used the crosslinker Vestanat B1186 A – which is approved for food contact applications by the US Food and Drug Administration (FDA) – to impart the requisite levels of chemical stability and flexibility to the new polyesters.

Sterilisation tests have shown that Dynapol L907 and Dynapol L914 give the strongest results when used with spicy or high staining foods on metal surfaces.
