Metallic screw capping with threaded plastic or aluminium insert for still wines
Scope of application
This document applies to the screw capping of still wines with a metallic closure having a threaded plastic or aluminium insert and a tamper-evident band which needs to be snapped before it can be opened. The closure is screwed and crimped during capping. The application shall be done only on a BVS finish according to EN 16293 - PACKAGING - GLASS PACKAGING - DEEP BVS FINISHES FOR STILL WINES. standard. This provides a seal on the top and evenly on the side of the finish. The term “still wines” does not exist in the legislation. This category includes all wines except sparkling, nor soft or natural, etc, and for which the overpressure due to carbon dioxide is below one bar in sealed containers when kept at a temperature of 20°C. Still wines are defined as having a level of carbonation below 1,2 grams per litre of liquid.

This joint group aims to coordinate the production of documentation at the junction of glass container production and closure application. It accompanies the development of documentation for glass containers for different types of closures including, but not limited to, aluminum screw caps, crown caps, and their components (liners). This joint group also provides an opportunity for cap and liners manufacturers to open discussions on specific work items of the permanent glass groups
