The 'DT's data sheets are categorised as general technical documents, specifically dedicated to glass and PET packaging (containers). They cover various aspects, including dimensional tolerances of glass containers (including the DT15 series for glass flacons), neck finishes, and glossaries for caps like ROPP/metallic screw caps, stoppers/cork, and plastic caps. Additionally, these sheets encompass test methods such as decoration on glass bottles, impact tests, label adhesion tests, and liner compressibility tests. Laser coding technical data sheets are also included in this category.
