Cetie continues to actively modernise its reference documents

The year 2022 enabled us to reconnect through in-person meetings with Cetie’s experts in Europe while, for the time being, remote meetings continue for other continents. However, the capacity for many of our members to travel has been restricted and hybrid meetings, which before the pandemic saw 90% of participants coming to Paris, now have an equal balance between those there in person and those attending remotely. As such, our working methods are evolving to accommodate this new reality, but all participants still continue to support the organisation of face-to-face events.
Translation work also continued in 2022. Twenty-one documents were translated, including a complete guide translated into Spanish, a language that is not yet prominent in our library.

At end 2022

The main finishes for glass bottles have been revised

The crown finish for beer bottles is now available in a ‘’smoother ‘P’ point” version, a variant of the traditional crown finishes (ISO 12821 and 12822).

Similarly, the “MCA” finish designed for pressurised bottles, particularly sparkling water, for metal or plastic caps, has been carefully reworked, with harmonisation between the versions and a clearer definition.

Other glass finishes are being updated, such as the cork mouth finish (EN 12726), the bar top stopper finish (port wine bottle type), the Verplast finish (for plastic caps, normally used on oil and vinegar bottles), or the “swing stopper” finish designed for beer or traditional lemonade bottles with an imitation ceramic closure system that can be closed using a metallic lever wire.

Finishes for PET bottles are adapting to the “Tethered Caps” Directive

The first finish specially designed to receive tethered caps, GME30.40 – PET Finish 26/22-15,1-1/2,3, has been published and validated by industrial experience, after more than one billion bottles were sold.

The test methods applied to caps for PET bottles have been improved

Guidelines No. 18.01 define the 11 main test methods allowing qualification of snap-top type caps.

Perfume flacon decoration test methods have been harmonised

The main test methods (eight in total) have been established and finalised over the past two years, working closely with perfumers and glass manufacturers. A new “generic bulk” (or simulant) has also been developed that is better suited to modern EHS (Environment, Health, and Security) standards and is closer to new perfume types.

Progress by all of the working groups

2022 saw the emergence within Cetie of the “Reuse of food and beverage containers” group (see Newsletter#2), which met in March for the 4th time. The other groups were not to be outdone, with the series of five newly designed finishes in the “Home & Personal Care” group, PET finishes published or revised with stakeholders from the PET sector, and two revised and expanded PET guides.
