The volumetric controls that currently apply to LAGs were developed and disseminated by ICAO following the unveiling in 2006 of a terrorist plot to sabotage aircraft in-flight by assembling an improvised explosive device using hazardous ingredients carried in seemingly ordinary LAGs.

Security tamper-evident bags (STEBs) were developed to allow an exemption to volumetric controls for liquids purchased at airport retailers or on board aircraft and carried by transfer passengers. Details concerning their production, of particular interest to potential suppliers, are available on the linked pages.

LAGs include (but are not limited to) water and other drinks, soups, syrups, jams, stews, sauces and pastes; foods in sauces or containing a high liquid content; creams, lotions, cosmetics and oils; perfumes; sprays; gels including hair and shower gels; contents of pressurized containers (e.g. aerosols), including shaving foam, other foam and deodorants; pastes including toothpaste; liquid-solid mixtures; mascara; lip gloss or lip balm; and any items of similar consistency at room temperature.


General guidelines
LAGs purchased at airport retail outlets or on board aircraft during the day(s) of the journey may be allowed through security screening points provided that they are carried in a Security Tamper- Evident Bag (STEB).

Production of STEBs
STEBs are to be manufactured in accordance with the technical specifications listed in the next menu <SPECS> as above.

Security procedures should be implemented to ensure that STEBs are not subject to misuse, abuse or any other circumstances that could lead to an act of unlawful interference.

The STEBs should be packed in sealed cartons (or any other suitable form of containers) with adequate measures to show proof upon delivery that the cartons had not been tampered with. The cartons should have adequate inventory records.

Delivery and storage of STEBs
Upon delivery of STEBs to the airport retail premises, the airport retailer or the aircraft operator should implement reasonable security measures to prevent unauthorized access to or unauthorized removal of the STEBs during storage, delivery to the retailer’s outlets and from their temporary holding premises pending their use at the point of sale.
Movements and deliveries of STEBs are subject to appropriate authorization and record, facilitating subsequent tracing and auditing, if required.

Suppliers of LAGs and STEBs should be encouraged to provide a declaration of the measures undertaken to ensure the implementation of the security of the supply chain. Such a declaration should include the following:

  1. 1.a)  confirmation of the appointment, in writing, of a company person responsible for security;
  2. 2.b)  a statement that all persons with access to supplies have received proper security awareness training that provides for an appropriate level of security prior to having access to LAGs and/or STEBs; and
  3. 3.c)  appropriate security checks are conducted prior to supplies of LAGs and/or STEBs being brought airside.

Airport retailers, aircraft operators and, where appropriate, suppliers should be responsible for ensuring that the chain of security relevant to supplies of LAGs and/or STEBs is maintained from the first point of entry airside until delivery to passengers.

TSG® STEBs certified with ICAO can be tamper-evident in all circumstances, i.e. for any type of tampering attempts (temperature, solvent, cutting, pre -tampering, etc.), and for any period of time (duration of the journey or longer).

  • Bag Dimensions
    The dimensions of a TamperSTOP® security bag will vary according to specific customer requirements.
    The external dimensions of a TamperSTOP® security bag are described in mm as follows: Internal bag width (A) x Internal bag length (B). This is illustrated below.

    The useable dimensions are described as follows: External bag width = A + 35 mm sides weld, External bag length = B + 15mm bottom weld + 100mm Handle.
    All dimensions may vary within the following tolerances:

     Bag width (up to 300mm)


     Bag width (300mm+)


     Bag length


     Bag thickness


    Certain dimensions remain constant regardless of the overall dimensions of the bag. 

    Track & Trace Features and Number Management
    A unique number can be printed on each bag. This number can be printed in human eye- readable form and in high definition barcode form.
    Barcode symbology and check digit formula will be agreed with individual customers. Minimum decode rate for barcodes will be grade C according to the CEN/ANSI standard.
    The position of number and barcode printing is agreed with individual customers and is as indicated and approved on bag artwork.
    Configurations available include picket and ladder and extra high barcodes (up to 50mm) for first time scanning.

    Picket and Ladder barcode configuration    
    Software systems and stringent procedures are in place at TSG to ensure that the number sequences printed onto TamperSTOP® security bags are as agreed with customers and in particular that no numbers are duplicated.
    All data is electronically collected at point of manufacture. TSG reports on the number ranges printed on bags as follows:
    Carton: the label on each carton indicates the actual number range in that carton along with any numbers missing from that range, upon the client’s particular requirement.
    Pallet: the pallet manifest contains a summary of the cartons on the pallet. It lists the actual number range along with any numbers missing from that range. The manifest is available printed as an A4 sheet, via e-mail or in a format suitable for loading into the customer’s system electronically.

    TamperSTOP® Security bags are printed to specific customer designs. Customer approval of paper artwork proofs and colour samples is required before any manufacturing can proceed. The process used is flexographic printing.

    TamperSTOP® security bags are packaged according to specifications agreed with individual customers into polythene bags and cartons and onto pallets as required.
    The following information is printed on the box labels: date of manufacture, TSG order number (manufacturing batch), quantity, and box number. In addition, if bags are uniquely numbered, the start and end numbers of the range of numbers in that box will be recorded along with a record of any numbers missing from the sequence.

    Storage Conditions
    The envelopes must be stored in cool dark conditions, in their original packaging until required for use. It is especially important that they are not exposed to sources of ultra violet radiation, such as strong sunlight or positions close to fluorescent lamps.
    Recommended storage conditions are 18 to 22oC and 35-55% relative humidity. The envelopes must not be exposed to temperatures above 35oC for prolonged periods before use.

    Shelf Life
    Under the conditions specified above, the envelopes will remain suitable for use for a period of 24 months.

    TSG maintains records that allow full traceability of any envelope back through the production processes to its raw material constituents. Quality control records are held for 4 years. TSG Security & Durable Mailers is ISO 9001:2000 registered.

    Intellectual Property Rights & Trademarks
    TSG is the market leader in developing tamper-evident packaging solutions for cash and valuables handling. TSG has pioneered tamper-evident security bags to the current levels of performance. Many of these developments are the intellectual property of TSG. In order that TSG’s intellectual property be clearly communicated and protected all TamperSTOP® security bags carry the patent information.
