This permanent group is dedicated to a wide range of topics downstream of the production of glass bottles and jars dedicated to the food and beverage industries:
- Surface treatments, marking, labelling;
- Testing methods (impact, headspace, internal pressure, etc.);
- Nomenclatures (of finishes, jars, bottles, and visual defects, etc.);
- Quality management (food and beverage safety, best practices, regulations).
