Quality assurance

In both production laboratories the quality assurance is verifying the specified quality as well as the suitability of our products every day.

The implemented tests provide detailed and absolutely reproducible results and guarantee highest product quality.

The integrated hygiene management ensures that we produce according to strictest hygiene directives and under satisfactory hygiene conditions at both plants in Lauterbach and Sünna. This also confirms the certification according to the global standard of hygiene management norm BRC packaging.
