The Austrian headquarters of the Stölzle Glass Group started its manufacture of hollow and packaging glass in 1871, formerly being a production site of flat glass. Over the past 20 years, Stölzle has turned into one of the leading producers of high-end glass packaging worldwide.

Investments in all aspects of production, quality control and logistics together with its motto “STO success is based on successful employees” have turned Stölzle into Europe’s leanest and most efficient producer of  pharmaceutical glass packaging as well as miniatures for food & spirits.


The flagship for Healthcare & Consumer products is proud of its important role as pioneer in glass production:

  • certification according to GMP since 2002
  • certification according to ISO 15378 since 2008
  • certification according to BRC/IoP standards for food packaging since 2009
  • Austria Gütezeichen
  • ISO 50001 since 2016



The production amounts to almost 1.5 billion pieces of container glass in white flint, amber and green glass each year, what reflects an impressive output of 250 tons of glass every day.
