Collaborative development agreement to generate global beverage industry voluntary guidelines

Today ISBT and Cetie announced a formal agreement of a novel collaborative approach to jointly develop and distribute global beverage industry voluntary guidelines. Significantly, this agreement allows both organizations to utilize a new shared platform to create guidelines and document best practices within their respective memberships in Europe and North America. The result will be a unified guideline that can be used by global brands and their suppliers while creating, producing, and packaging their products.


Co-production of harmonised guidelines

Both organizations often address the same topics in the beverage industry. ISBT and Cetie will now combine efforts and co-produce harmonized guidelines, nomenclatures, specifications, or test methods that provide consistency across the global beverage industry. “Now anyone in the global beverage industry wishing to adopt the best of industry practice can access guidelines from both ISBT and Cetie,” says Larry Hobbs, Executive Director of ISBT about this agreement.

Gone are the days of silos by regional area, and the various regionalization of protocols, which added cost and confusion at a brand and supply-side companies.

As a secondary benefit, the most common problems are global, not regional. “Now solutions can be quickly adopted for the largest consumer markets,” says Josquin Peyceré, Secretary-General of Cetie.
Consumers today are concerned about the safety and security of all food products. This agreement will leverage the best in beverage industry technical knowledge in responding to the development of new beverages, processes, and packaging.” As part of this agreement, both organizations are launching their first jointly produced guideline. A significantly updated Plastic Bottle Closure Qualification Test Manual will soon be made available to the public. The manual will allow brands and suppliers to reduce qualification costs and prove out new lightweight closure designs. This is a win – both economically and for improved sustainability – for the global beverage industry. The industry can expect more collaborative efforts soon.

This document provides a collection of test methods for the qualification of plastic flat-top closures applied on PET bottles that are used in the beverage industry. This document has in view to ensure that every party involved in measuring and determining results consistently the same way. It should be understood that specifications have always to be agreed upon between the packaging supplier or packaging technology supplier on the one hand and bottler or brand owner on the other hand. It needs to be considered that closures are a part of the entire packaging system. (88 pages - 39 tests  (see below) and numerous additional information!)
