Aluminium screw caps for pressurised liquids on BVS glass finishes

Scope of application

This data sheet gives specifications and dimensions for aluminium caps designed for BVS-type glass finishes according to EN 16293 GLASS PACKAGING - DEEP BVS FINISHES FOR STILL WINES WITH REDRAW ON APPLICATION, FOR PRESSURISED WINES AND OTHER LIQUIDS TO A MAXIMUM PRESSURE OF 2,5 BAR AT 20°C (max 4 bar in service).
 
Higher carbonation levels require specific conditions to agree between the filler and the cap supplier. Only long skirt caps are considered in accordance with current practice at the time of writing.
 
Note that as stated in this standard, the use of this finish for wine with a CO2 content > 1,2 g CO2/l. is subject to prior agreement between the cap supplier, the glassmaker and the filler. It concerns the cap before application with generic information on liner characteristics.
  • It does not specify a liner type, for which several alternatives are available according to the requirements of the product and customer preference;
  • It does not cover caps for shallow finishes and is only available for "BVP" type closures which cannot be used for pressurized beverages;
  • It does not cover short-skirt BVS capsules which are practically not used in pressure applications.

Vice WG chair : Mr. Giuseppe MENCACCI (Process innovation manager - GUALA CLOSURES S.P.A.)
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
