The series focuses on Glass and PET Finish Geometry (GME),
providing information about the upper part of bottles or
jars known as the "neck." It covers specifications for measuring
neck finishes, including drawings, definitions, and dimensions for
plastic and glass bottles. Various neck finish types, such as PCO,
ROPP, MCA, and FEA, are available for download. The importance of
these specifications is highlighted for designing molds, ensuring
closure functions, compatibility with bottling lines, and serving
as a basis for new designs. Special considerations include
compatibility with the bottled product, filling conditions,
heat treatments, storage, and distribution conditions.
The data sheets emphasise collaboration with bottle manufacturers
to minimize manufacturing defects.
