PET plenary
WG chair: Alessandro FALZONI - SACMI IMOLA
This joint group is in charge of all GME data sheets ("Finish data sheets"), dedicated to the geometry of PET neck finishes and their related documents. These data sheets are related to finishes dedicated to the beverage industry (such as soft drinks, mineral water & wine), packaged in an aseptic environment and/or with nitrogen injection, and to the food industry (e.g. edible oils, vinegars, and sauces) and allowing to receive mainly plastic caps.
