Picture of Choosing the Best Security Seal for the Job

Choosing the Best Security Seal for the Job

With the range and breadth of security seals on the market, it can be very challenging for the uninitiated to know which seal to choose to best suit their needs. From the outset, it is recommended that the decision-maker considers the purpose of the security seal in relation to the application. Considering some of the fundamentals from the outset will help to select the right seal for the job…

…why is the user sealing the enclosure in the first place? Is it for loss prevention, safety purposes, product integrity, brand assurance...?

…what type of goods will be protected? What is the value of the goods?

…where is the seal going, and how? Cross-border shipments are subject to customs regulations which will affect the seals that can be used

…what kind of resistance is required? What are the consequences should if the security seal has been broken or tampered with?

…what environment is the seal being used in? What is the operating temperature? How long does the seal need to last for?

Answers to these questions will have a bearing on the material, form, shape, strength of the most appropriate security seal.

It should also be noted that a security seal alone cannot provide an iron-clad guarantee of integrity. No manufacturer anywhere in the world can say with complete certainty that – given enough time, appropriate circumstances, resources, skills and ingenuity – their security seals are undefeatable... but this is also true of safes, door looks, padlocks and alarms. Security seals should always be used as one layer within an ‘onion skin’ of security (view our guide to security protocols).

With this said, below we note some key characteristics of seals you should consider when choosing the most suitable. Try out our handy filtering tools shown on our main security seals category to find a product matching your needs.

Seal FeatureConsiderations
Design Type

Seals come in many forms... Pull-through Security Seals, Fixed-Length Security Seals, Security Padlock Seals, Barrier Seals (Cable Seals and Bolt Seals), Wire/Rope Meter Seals, and even Reuseable Electronic Seals. Security seals also include security tapes and labels, suitable for flat surfaces and edges on enclosures such as crates, cartons and pallets. Each type is designed for particular types of applications - for more information, see types of security seals.

Physical Fit (Diameter, Length and Flag Size)

Each security seal will have a particular tail or hasp diameter, an effective useable length, and a standard flag size for visibility of printed identification markings. Narrower seals are useful where seals must fit into smaller apertures, and for this many of our pull-through seals have smaller diameters, such as the MiniLock 570's 1.4mm tail thickness and UniTite 414's 2mm thickness. We also offer extra long seals, such as the UniStrap 412-XL (overall 51cm length) and UniTite 413 (overall 49cm length). In terms of flag size ("marking area"), we offer specialised security seals such as our UniFlag Security seal, which has a large format (108x56mm size). 

Material

Common materials in use for security seals are polypropylene, nylon, aluminium and steel. Polypropylene is a popular choice for pull-through seals, as it offers a combination of strength, flexibility and wide operating temperatures. However, all types of plastic do become brittle at increasingly low temperatures, and do degrade when exposed to UV light, long-term saltwater exposure, solvents etc. Metal aluminium and galvanised steel cable seals provide more durability and strength where circumstances dictate, and we can also specify stainless steel cable grades for most demanding applications: see our Flexigrip 150M and Flexigrip 325M models.

Strength

Seals are specified for particular strengths – for certain applications such as fire extinguishers, kit bags and first aid trolleys it is desirable to have a very low break-strength so that seals can be broken in an emergency – for others, for example mail sack security seals, it is important that seals with strong break strengths are used so that bags do not burst open when under tension. There is a wide range of tensile strengths available, from 5KgF all the way up to 2000KgF, so understanding the possible forces relevant for your application is important for specifying the right kind of seal.

Level of Tamper-Evidence

We categorise our security seals as having either a Low, Medium or High degree of tamper-evidence, based on design and construction features, method and material of construction, and level of certification.

ISO Classification

Linked to the above, higher levels of security seals are often required for international freight movements - in particular, High Security Seals as classified under ISO17712:2013 regulations for international shipping container and freight movements.

Removal Method

Some applications require easy-access into a sealed enclosure, and for this we have security seals that can be removed easily by hand, either with low-break strengths (see our Fireseals) or tear-line features (see our Tracewaste Tear-Off and UniStrap 412LT).

For other requirements, security seals need to be robust and should not be removed intentionally without simple tools such as scissors or tin-snips, such as our UniTite 413.

In other scenarios, particular for barrier seals, we have our heavy-duty cable and bolt seals, products such as our Flexigrip 325MFlexigrip 500M and Fork seals which necessitate the use of heavy-duty cutting tools like bolt croppers to remove.

Sustainability

Sustainability should of course be at the heart of every business, and security seals should be no exception. All of our plastic security seals are 100% recyclable, and we are increasing options for recycled content and biodegradable security seals on a regular basis.

Universeal UK has been supplying security seals since 1992, and we are one of the leading organisations in the industry.

Picture of Security Seals for Known Cargo / SPX Cargo

Security Seals for Known Cargo / SPX Cargo

The Department for Transport, as part of a European wide regulations to standardise and improve aviation security, oversees the ‘known consignor’ scheme for consignments, whereby authorised and audited operators may apply their own in-house measures for the secure preparation of cargo destined for despatch by airfreight. This allows expedited cargo movements for those who follow best practice in the industry. Such cargo is classified as ‘known cargo’ or ‘SPX cargo’.

An application to the DfT for approval as a Known Consignor will be followed by a visit from a DfT accredited validator. If the shipper’s safety and audit controls meet the requirement they will be issued a unique identifier. Further information is available from the specialist aviation regulator, the Civil Aviation Authority (please visit: www.caa.co.uk).

Security seals are an important part of this process, both for the shipper who processes and packs goods for cargo movements, and for logistic operators who handle consignments between locations. Indicative seals, such as cable security seals and non-residue security labels, are uniquely numbered and provide suitable tamper-evident security to protect against unauthorised interference.

As an example of how such security seals can assist in practice, consider the role of a courier company transporting safety-critical aircraft parts between suppliers and secure airport facilities. If the goods are sent from a known consignor, who is accredited under national regulations, then consignments can be loaded within vans at the supplier facility, and a security label placed over the side and rear doors to verify the authorised loading. This allows the consignment to proceed directly for embarkation at airport. On the other hand, if they are not a known consignor then the load will have to proceed to a cargo handler, to be x-rayed and security validated. The consignment can be then sealed in the van in the same way, and proceed to the airport.

Security seals will be checked at the airline to make sure they have not been broken or tampered with. Our indicative plastic seals for trailers, cable security seals for air cargo containers, and security labels for vans can assist in the smooth operation of known cargo / SPX cargo operations. All of security seal products are available on short lead times and with bespoke customisation for your needs (for example, customer logos, barcoding/numbering, and other security features).

Picture of Securing your parcels against tampering or damage in transit

Securing your parcels against tampering or damage in transit

Sending parcels and documents, at home and abroad, is always fraught with risks; once it leaves your sight, who knows really who might attempt to access, steal or otherwise interfere with the consignment you are sending?

Couriered parcels are usually handled by many parties, including multiple handlers at local and regional courier depots; third-party drivers; customs inspectors, airport handlers and more. Each step in the process involves the potential for access, tampering or theft. Such access need not necessarily be illegitimate – for example, customs authorities, as part of the controlled flow of goods, are required on occasion to visually inspect the contents of a consignment to check that they conform to the description noted in export paperwork.

The problem is knowing whether or not your consignment has been handled or damaged – and whether inspections of valuable, fragile or sensitive items need to be carried out to ensure that they have not been compromised.

Without actually being there, how can you do this? One way is to secure your consignment is with tamper-evident security labels or security tape. There are many types of security label or security tape, suited to the particular requirements of the item to be sealed:-

 

                                 

Residue security labels; designed so that when peeled back they leave a mark or residue on the application surface to which they were applied.

 Non residue security labels  

Non-residue security labels; designed so that when removed they visually deform on the labels surface, leaving the application surface clear.

 Residue security labels  

Residue Security Tape; suitable for sealing cardboard boxes and other containers – it can be used in conjunction with a normal packaging tape dispenser. The tape is marked and leaves a VOID on the sealed packaging upon removal.

 Plain residue tape  

Plain Security Tape; a plain tape which looks visually very similar to traditional brown packaging tape, so as to avoid any unnecessary attention from opportunists. However, once the tape is removed a VOID residue is left upon the box.

   
   

Such products can be applied to seal and secure any flat surface, such as inner packaging, cartons, mail bags and envelopes, to deter and minimise the risks of opening. Once applied, such labels or tape act as a quick visual reference for the user as to whether or not sealed items have been accessed: once opened, the product physically and permanently changes state with a VOID message appearing on the surface of the product.

This gives control back to the company or individual sending the parcel: for example, using tamper-evident labels will ensure that customs handlers record checks made on consignments, giving you more information on which items have been opened and handled during transit.

Take a cardboard box for example, lacking any sort of locking hasp to accommodate a plastic security seal, security labels can be placed across a carton’s point of access. This ensures that a handler, for example a custom official, is required to peel back or cut the label.

The incorporation of sequential numbering onto security labels also means that they cannot simply be easily replaced to conceal the opening; when the consignment reaches its destination, it is clear if it has been searched because recorded numbers will not match.

————————————————————————————————————————————————————————————

Of course, security labels aren’t just limited to this sort of application, they can be used in many different ways such as asset identification and to display warranty and servicing information. Some security labels also employ other methods of tamper evidence like the destructible label, which fragments upon removal – meaning that it is impossible to remove and re-instate.

Picture of Cargo Security: Sealing Vans, Trucks and Trailers

Cargo Security: Sealing Vans, Trucks and Trailers

Securing your assets against theft and interference whilst in transit is more important than ever in our globally-connected world. Security seals are an important part of the security process; helping to ensure that your goods arrive at destination as expected, without delay.

Security seals come in various forms to suit particular applications, and in this article we run through the different types of seals which are suitable on various forms of road transport vehicles.

Transit and Small Van Security

Security Labels

Small transit and other small courier vans do not feature locking hasps or other features which would allow for sealing by way of an indicative pull-tight or fixed length seal.

Instead, non-residue security labels can be placed on the seam of vehicle doors, preventing access without removing the label and de-facing the surface, leaving a VOID message through the seal. Non-Residue labels have the advantage in that they do not leave a residue on the surface of the doors, avoiding damage to paintwork.

Vans with Roller Door Shutters

Indicative Pull-Tite Seals

Vans and other vehicles with roller-shutter doors feature hasp and staple-style locking arrangement. For these types of locks, we recommend use of a pull-tite or “pull-through” tamper-evident seal, which can be secured tightly around the mechanism, preventing interference by opportunists.

Pull-through seals are available in many different sizes and configurations. We hold most items in our UK warehouse; alternatively, we can customise with your bespoke marking, logo and custom numbering.

 Articulated Lorry Trailer Doors

Fixed-Length / Ring Seals

Trailer doors are available with a number of different locking mechanisms, and so the preferred security seal will depend on the mechanism in question - either pull-through or fixed-length seals are recommended.

Fixed-length or "ring" seals, form a secured loop through a locking aperture. Ring seals do not “pull tight” around the locking arrangement, meaning that they can be freely rotated, checked and inspected for signs of tampering more easily.

Curtain-Siders

Fixed-Length Seals and TIR Cords

Curtain sided trailers are best secured using a TIR cord to pass through each of the buckles along the trailer, looping around so that TIR fasteners can be secured at the back of the vehicle using a plastic indicative fixed-length seal. This ensures that the only way to access any side of the trailer is by way of breaking the seal, providing the audit trail required.

Containers on Trailers

High-Security Bolt Seals & Plastic Indicative Seals (empty loads only)

Fully-loaded shipping containers which are being moved internationally require sealing by way of a security seal designated and tested as ‘high-security’ according to ISO17712 and CT-PAT regulations. Our high-security bolt seal is one of the most well-established on the market and fully compliant.

For empty loads, we recommend use of plastic indicative seals – providing peace of mind that empty containers have not been accessed against the knowledge of the legitimate user, reducing risk of foul play.

Open Top Containers

TIR Cords & Plastic or Cable Seals

Open Top containers allow bulky items to be loaded directly from above. They usually covered and secured using a tarpaulin. TIR cords should be used to pass through the tarpaulin cover eyelets and around container corner posts or lashing rings. The TIR fasteners can then be secured with a security seal – either an indicative plastic seal, or where the goods are being shipped internationally, a high-security bolt seal or cable seal.

Oil, Gas & Bulk Liquid Tankers

 
 Security seals for oil and bulk liquid tankers

Flexible Cable Seals

The valuable and potentially hazardous contents of tankers are at risk of interference, theft and fraud, especially whilst in transit and away from the legitimate user.

This makes it crucial that sensitive and valuable access points, such as valves, meters and hatches are strongly secured against tampering. Flexible, variable length and very strong cable security seals are ideal for ensuring such access points are secured against interference.
