Cetie Bottling Guides are intended to help bottlers avoid defects when using the closure systems in question. Cetie has recently supplemented its publications with a new Bottling Guide No. 11 which specifically addresses the identification and correction of defects in capping with ROPP (Roll-On Pilfer-Proof) closures. This document was developed during the sessions held by Cetie’s groups of experts, convened to revise Bottling Guide No. 6 Metallic Screw Capping for Still Wines on BVS-Type Glass Finish (published in 2016) and Bottling Guide No. 2 Metallic Screw Capping for Non-Carbonated Liquids, Foodstuffs and Pharmaceutical Products (revision in progress) and to produce Guide No. 9 Metallic Screw Capping of Pressurized Wines & Other Beverages on BVS-Type Glass Finishes (published in 2016). Initially, the intention was for the first of the above documents to include one chapter devoted to the identification and correction of capping defects. It rapidly became obvious, however, that given the quantity of information available and its applicability to all the ROPP closure applications, it would be worthwhile developing this chapter to produce a reference document in its own right. Guide No. 11 now comprises 41 pages, contains 44 illustrations and lists 26 types of capping defects with their possible causes and the appropriate corrective actions. At present published in English, the main working language of the groups involved, under the title Aluminium Screw Capping Defects – Identification and Correction, the French version will be published shortly, along with the revised Guide No. 6 and the new Guide No. 9.
