Recommendation data sheets (FS)

Cetie FS Series – Recommendations for Bottlers and Their Suppliers

The FS series includes a collection of recommendation data sheets specifically designed to support bottlers, container manufacturers, and closure system suppliers throughout the bottling process.

Developed by industry experts, these documents provide practical guidance and shared technical knowledge on a wide range of topics, such as:

  • Fundamental definitions, calculation methods, and physical principles relevant to packaging design and bottling operations

  • Safety and hygiene requirements, including critical hazard prevention, food safety management, and risk assessments

  • Conformity assessment and certification in line with European directives

  • Good practices for filling lines, storage, traceability, and pressure management in bottles for carbonated and still beverages

  • Headspace specification, tamper-evident finishes, and label application

The promotion of a common language and shared expectations between bottlers and suppliers, complementing Cetie’s quality guidelines. These sheets are essential tools for ensuring consistency, compliance, and product integrity across the packaging and bottling value chain.

This page provides an indicative list of Cetie documents.

This fact sheet gives requirements and controls to be observed during glass manufacture to help ensure the optimum performance of containers with Vacuum Lug and Press-on closure systems. These are in addition to the dimensional and other requirements within existing national and international standards. These are essential for proper and effective sealing of containers with vacuum lug and press-on finishes.

This data sheet gives guidance on the relationship between the internal pressure strength standards used for process control at the point of manufacture and the pressure strength standards applicable at the point of receipt of the bottles by the bottler and in the case of refillable bottles, the pressure strength standards which might be applicable to the pool of refillable bottles.
01/01/1998 - Latest update 26/07/2017
FS05.00 - Warehousing of filled glass containers

The following guidelines are essential for proper transport and storage of glass containers with vacuum lug finish and closure. Lack of adherence to these guidelines may result in loss of package integrity and stack stability.

FS07.00 - Design headspace recommendations for liquid products in bottles and jars
This document specifies design headspace recommendations for liquid products in glass containers. It does not concern containers for powders and tablets or flaconnage-type bottles. Note that for food products in wide-mouth containers with a vacuum seal closure, fill levels determine the level of vacuum obtained and are the responsibility of the filler and the cap supplier. The actual headspace achieved in the filled product is the responsibility of the filler. For general information on the physical principles governing headspace requirements, refer to Cetie FS15.00 - PHYSICAL PRINCIPLES FOR CONTAINERS FILLED WITH NON-CARBONATED PRODUCTS.

FS08.00 - Recommendations for design of cork removal devices
This data sheet gives recommendations for the design of devices for removing corks from wine bottles. Corks can be made of cork or plastic/synthetic material. 
01/03/2002 - Latest update 01/03/2002
FS09.00 - Relationship between mass and capacity for glass containers (Alpha factor)
This data sheet proposes a relationship between mass and capacity for normal glass bottles. This relationship, named alpha, can be considered as the lightening factor of a container, independently of its volume. For instance, a 1,5 l bottle with an alpha of 14 has the same lightening factor as a 66cl bottle with the same alpha of 14. In the first stage of development of a new container, it helps designers find reference weights for comparison, by giving them equivalent containers, to propose an initial weight for the new container.

FS12.00 - Traceability - Recommendations to bottlers and packers
This fact sheet has been set up by the Quality Committee of Cetie. Its objective is to help bottlers or packers to establish the traceability of packaging in the final product. These recommendations do not concern the liquid beverage, only the packaging and the bottling activity. The study is not intended for a specific type of business, it is a guide from which the user can take what suits his own needs. Traceability has a cost that increases proportionally to the precision sought from the system.

FS15.00 - Physical principles for containers filled with non-carbonated products
This fact sheet gives an overview of the physical principles which govern the behaviour of still liquids when bottled in rigid containers and the consequences in terms of head space requirements. It concerns in particular glass containers for which elastic deformation can be considered to be negligible, though some of the principles may also apply to other packaging types.

FS24.00 - Glass flaconnage for pharmaceutical products - Recommendations for use of ISO 11418 parts 1,2,3 & 4
This document concerns the options which are to be selected by manufacturers and users from the following standards:
  • ISO 11418 - Containers and accessories for pharmaceutical preparations - Part 1: Drop-Dispensing glass bottles
  • ISO 11418 - Containers and accessories for pharmaceutical preparations - Part 2: Screw-neck glass bottles for syrups
  • ISO 11418 - Containers and accessories for pharmaceutical preparations - Part 3: Screw-neck glass bottles (Veral) for solid and liquid dosage forms
  • ISO 11418 - Containers and accessories for pharmaceutical preparations - Part 4: Tablet glass bottles
Recently published versions have increased the variants and options available, some of which should be identified at the outset of the design process. This would ensure consistency across production runs, suitability of the chosen closures and aid the retention of bore fitments if applicable.

This data sheet aims to guide users through the design options to be included in the quality specification documentation (“cahier des charges”) and on the drawing.

FS25.00 - Pilfer-proof finish - Definition and measurement of the neck finish height 'F'
This data sheet explains how the 'F' Dimension of a pilfer-proof (PP) neck finish should be defined and measured. It specifies clearly how the reference points of the measurement are defined, knowing that the lower point is a virtual point, not a physical point at the surface of the finish.
This definition is applicable to MCA, BVP (EN 15543 - GLASS PACKAGING - FINISHES FOR BOTTLES - SCREW THREAD FINISHES FOR BOTTLES FOR NON-CARBONATED LIQUIDS) and BVS (EN 16293 - PACKAGING - GLASS PACKAGING - DEEP BVS FINISHES FOR STILL WINES) finishes, and generally to PP finishes, unless other clearly specified reference points are defined in the corresponding standards.
This document is based on the British Glass GF910 data sheet.

The main issues are:
  • The dimension of the Chinese characters to make sure to print them clearly;
  • The control of the decorated bottles;
  • The level of defect that can be accepted.
Legal content :
  • Name of the product
  • Duration of use
