This permanent group is dedicated to the creation and revision of Cetie's "GME*" neck finishes data sheets, and also to the revision of equivalent neck finishes data sheets previously submitted to official standardisation (ISO and/or CEN), dedicated to the production of glass bottles and jars for the food and beverage sectors. These neck finishes data sheets concern the following applications: ROPP, aluminum screw caps, crown caps, twist-off caps, cork or synthetic stoppers, bar-top, or swing stoppers.
*Initiated by the glass industry in the 1960s, the acronym 'GME' stands for 'Glass Manufacturing Experimental'. The idea was that Cetie, as an unofficial standards body, would only publish 'experimental' data sheets, before submitting these to the official standards bodies. At the same time, in the USA, the acronym 'GME' was also used. As the original meaning was lost over time, this nomenclature for Cetie's glass finishes documents has been, later on, applied to the PET finish data sheets.
