Bottling & capping Guides

Practical Bottling Guides for glass and PET packaging

 
 
These guides define and compile current best practices specific to the interoperability of a package with its closure system depending on the nature of the product being bottled. These guides bridge the gap between customers and suppliers by providing precise technical terminology.
 
They also help to :
  • ensure the correct functionality of the assembly interfaces of the various components;
  • limit the modes of application to certain equipment and specific operating conditions;
  • determine possible performance limits and related individual responsibilities;
  • Fulfil the supplier's obligation to inform users;
  • provide references to the relevant standards and regulations;
  • to ensure the highest level of consumer safety by placing safe and healthy products on the market;

 
GUIDE N° 1 - CAPPING OF STILL WINES ON A CORK MOUTH FINISH

Scope
This guideline applies to the capping of still wines with a cork mouth finish as per CETIE data sheet GME 50.01 which has been used as a base for the European standard EN 12726.
If application is done on another finish, the user must carry out sealing tests to ensure that this application is technically acceptable.
The term “still wines” does not exist in the legislation. Still wines are defined as having a level of carbonation below 1.2 grams per litre of liquid, and for which the over-pressure due to carbon dioxide is below one bar in sealed containers when kept at a temperature of 20°C.
For wines with a level of carbonation above 1.2 grams per litre of liquid (but below 2 000 mg), suitable stoppers must be used (diameter above 24 mm for natural cork, to be defined for other types of stoppers).

GUIDE N° 3 - TIRAGE (BOTTLING) AND FINAL CORKING OF QUALITY SPARKLING WINES PRODUCED IN SPECIFIC REGIONS (QSWPSR)ON 29-MM AND 26-MM CROWN CLOSURE. (NF H35 029)

Scope
The initial documents (1), drawn up in conjunction with professionals in the wine sector, enabled us to better understand the needs of producers of high quality sparkling wine.
To respond to the constraints and problems of QSWPSR capping, it was important that all material and equipment producers can supply and guarantee specifications and guidelines in order to ensure successful capping, filling and shipping and to respect required storage and transport conditions.
Although apparently a very simple operation, effective corking has to be regularly checked throughout the process, as quality and the protection of the product’s initial value cannot be left to chance. Flexibility in the composition of the work group has enabled us to call on different experts and specialists of the closure process to throw light on different problems.
Two complementary concerns prevailed in this work:
  • Suppliers’ obligations to state not only what materials have been used but also provide information regarding the entire closure process and its limitations, as covered by interprofessional agreements
  • Drawing up a set of structured and recognised quality guidelines that provide a fundamental tool to respond to the needs of quality assurance. Although the obligation to inform is already included in product specifications, providing information on their application must also be provided.
All the groundwork - conformity of supplies, conditions of use, limitations and necessary verifications – has to be done for quality assurance to be ensured. This guide will also help in diagnosing any eventual problems.

GUIDE N° 4 - 26 mm CROWN CAPPING

Scope
This document concerns the crowning process, using crown caps for which the seal is provided by a plastic liner, onto glass finishes adapted to either "pry-off" or "twist crown" applications. It mainly focuses on capping with crown caps designed with a 6 mm height and a 26 mm diameter, as defined in EN17177, onto glass bottles.
 
The main objectives of the document are:
  • to provide manufacturers and users with a reference tool that can ensure the correct procedures for crowning and also the safety of the consumer;
  • to give the specifications of each of the components and their interfaces;
  • to provide manufacturers and users with a reference document for drafting specification sheets and quality assurance procedures;
  • to simplify troubleshooting in the event of problems.
 
This guide represents the current situation and may be updated according to the development of new crowning technologies.
It has been drafted with reference to those standards that are either current or in preparation, and to other reference documents recognised in the industry, identified as pertinent.

GUIDE N° 6 - METALLIC SCREW CAPPING FOR STILL WINES ON BVS TYPE GLASS FINISHES - WITH REDRAW

Scope
This Guide gives information on good practice for bottling still wine with an aluminium screw caps on a BVS type glass finish according to EN 16293, with redraw of the cap on application.
For the purposes of this Guide wine is considered to be "still" with a CO2 content < 1.2 g CO2/l (as defined in EN 16293)
The Guide defines:
  • The functions of the closure and its limits,
  • The specifications of each of the components in relation to each other, to fulfil the global functions within determined limits.

GUIDE N° 7 - METALLIC SCREW CAPPING WITH THREADED PLASTIC INSERT FOR STILL WINES

Scope
This guideline applies to the screw capping of still wines with a metallic closure having a threaded plastic insert and a tamper-evident band which needs to be snapped before it can be opened.
The closure is screwed and crimped during capping. Application must be done only on a BVS finish. 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.
In this category are all wines which are neither sparkling, nor soft or natural, etc, and for which the over-pressure 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.

Guide N° 8 - PLASTIC SCREW CAPPING FOR STILL WINES

Scope
This guide concerns screw capping of still wines with a threaded plastic closure having a tamper evident ring whose bridges must break on opening
The cap is screwed on after filling and can be applied on a screw finish in glass or PET of the BVS type. This operation enables a seal to be ensured on the top and sides of the sealing surface.
Note
The term “still wines” is not currently defined in legislation; it is generally accepted practice to consider “still” wines whose carbon dioxide content is less than 1.2 g per litre of liquid and which gives an overpressure of less than 1 bar relative when maintained closed at 20°C. Wines entering in this category are neither “sparkling” nor “sweet” nor “natural”, etc.

GUIDE N° 9 - METALLIC SCREW CAPPING FOR PRESSURISED WINES & OTHER BEVERAGES ON BVS TYPE GLASS FINISHES - WITH REDRAW

Scope
This Guide gives the necessary information on good practice for bottling wines and other products with a CO2 content > 1.2 g CO2/l with an aluminium screw cap on a BVS type glass finish accomodating redraw of the cap on application.
Both the cap and the bottle must be foreseen for the application, subject to written agreement between the cap supplier, the bottle supplier and the filler.
It remains the responsability of the filler to ensure that the package is appropriately designed for the product bottled and foreseen conditions of storage and transport as well as to avoid risk of injury on opening.
Attention is drawn to the neccessity to observe special precautions for carbonation levels above ~3 g/l CO2 or a pressure exceeding 6 bars.
This guide does not cover the use of MCA type pressure caps or smaller diameter BVP type caps/finishes used with redraw.
The Guide defines:
  • The functions of the closure and its limits,
  • The specifications of each of the components in relation to each other, to fulfil the global functions within the determined limits.
Note that possible defects of applied closures and troubleshooting methodology are described in Cetie Bottling Guide n°11.
