Quality policy

Primary packaging materials for the pharmaceutical sector are our core business, into which we want to invest and further develop jointly. On the basis of the applicable GMP and DIN standards and considering the interests of our company and the environment, primary packaging materials are manufactured to the highest quality by acting responsibly, so that a permanently rising profit results from it for our stakeholder.

Our focus is on the quality and performances of our products as well as on product safety (hygiene) and consumer protection (e.g. as set out in the GMP, QA as well as EU regulations and domestic legislation).

Our processes are systematically verified and evaluated with the aim of guaranteeing the quality of our products and the on-going improvement of our Quality Management System.

Our guiding principles

„We create safety and confidence through quality and competence!“

For our company the following applies:

„Hygiene during manufacturing primary packaging materials for the pharmaceutical industry is not an imposed obligation, but a great responsibility for each and every employee!“

Quality assurance

1. Inspection of incoming goods (tubular glass, packing material)

2. Production-accompanying quality assurance
