“S G” mark on recent/modern glass containers (2000-to date)
Muncie, Indiana (head office), known (as of 2010) as Verallia North America. NOTE: Verallia North America (VNA) has officially been acquired by the Ardagh Group (based in Luxembourg) as of April, 2014.
This mark dates from the year 2000 to the present (as of 2014). The ” SG” mark is seen embossed on many of their modern jars and bottles, usually on the lower heel area of the container, but sometimes on the base. I have been told that Verallia will continue to use the “SG” mark on their glass containers even though the “official” company name was changed.
This concern was formed when Ball Corporation and Saint-Gobain (SG also acquiring Foster-Forbes Glass at that time) merged in 1995 to form Ball-Foster. In the year 2000, the name was changed from Ball-Foster to Saint-Gobain Containers.
Saint-Gobain Containers/ Verallia is a subsidiary of Saint-Gobain, France, a huge firm with a corporate history involved with glassmaking that goes back over 300 years. Saint-Gobain has diversified and expanded it’s range of products greatly over the last few years, so glass container manufacturing is just one important component of their enterprise. They are the “number two” producer of glass containers worldwide, after Owens-Illinois, Inc.
Verallia now includes 13 glass manufacturing plants in the United States, some of which are former Ball Brothers/Ball Corporation factories.
