This joint group aims to coordinate the production of documentation at the junction of glass container production and closure application. It accompanies the development of documentation for glass containers for different types of closures including, but not limited to, aluminum screw caps, crown caps, and their components (liners). This joint group also provides an opportunity for cap and liners manufacturers to open discussions on specific work items of the permanent glass groups
