SealsExpert Info


Security seals are mechanisms used to seal shipping containers in a way that provides tamper evidence and some level of security. Such security seals can help to detect theft or contamination, either accidental or deliberate. Security seals are commonly used to secure truck trailers, vessel containers, chemical drums, airline duty-free trolleys, tanks with different kind of fluids, and utility meters. Typically they are considered an inexpensive way of providing tamper evidence of intrusion into sensitive spaces.

Security seals are not designed to solve all security problems.

The effectiveness of seals is strongly dependent on the proper protocols for using them. These protocols are the official and unofficial procedures used for seal procurement, storage, record keeping, installation, inspection, removal, disposal, reporting, interpreting findings, and training. With a good protocol a modest seal can provide excellent security. On the other hand a sophisticated seal used poorly may be worse than useless if naively trusted.

High Security Seals

A High Security Seal is constructed and manufactured of material such as metal or metal cable with the intent to delay intrusion and have been designed to conform with world customs and ISO security seal standards. The International Standards Organization (ISO) published the new version of ISO 17712 on 15 May 2013. The major changes in the new edition concern Clause 6, Evidence of Tampering. Changes were required due to the demonstrated impracticality of tamper-related tests in ISO 17712:2010 edition.

Metal seals

cable sealThere are several basic designs of the metallic security seals: bolt seals, ball seals and cable seals.

Bolt seals are used to secure shipping containers, trucks, and trailers. A bolt seal used for securing containers must conform to the ISO 17712 high security seal in order to be accepted by customs all around the world in ocean shipping. The C-TPAT (Customs Trade Partnership Against Terrorism) specifies ISO 17712 compliant security seals to be used. Bolt seals are generally closed by hand (by pushing the seal body and head together) and opened with the use of bolt cutters. This gives a strong and secure seal for transportation while remaining convenient for staff in ports and warehouses.

Cable seals

Cable seals allow for more versatile application, as they have variable length of the locking mechanism limited only by the cable length. Typical applications include sealing trucks and railway cars transporting valuable commodities. An internal locking mechanism prevents the cable from being retracted. Most cable seals are classified as security or high security level as to ISO 17712.

All ISO 17712 compliant security seals are numbered on both seal body and head to prevent substitution of either part. This is usually done using laser marking which cannot be rubbed off.

Ball seals are commonly used for securing trucks. They consist of a metal strip with a punched hole, attached to a housing section. When the strip is bent and threaded through the hole, a ball inside the housing section locks it in place. Most ball type seals belong only to the indicative level as to ISO 17712.

Plastic seals

Plastic security seals are manufactured normally in two styles: with adjustable length or fixed length.

Variable length plastic seals, named also pull tight plastic security seals, can fit many applications from securing the neck of a bag or mail sack to sealing chemical drums, first aid kits, fire extinguishers, doors control acces, fuel cars tanks, water tanks, fashion items sold online, and cargo trucks. If you have to control access on however your need is the tamper evident, variable lenght plastic seals will offer you the right and priceless solution. Pull tight security seals have an adjustable length much like a cable seal but offer a much higher security level and an audit trail due to sequential numbering and the ability on some seals to be barcoded and have a company name and logo printed or laser etched on.

numbered plastic security sealsFixed-length seals tend to be more tamper resistant than variable length as there are no sliding parts, they simply ‘click‘ into place to lock, which can make them easier to fit than variable length seals. Most fixed length seals can also be branded and numbered for extra security. Fixed length is often the choice of single use security seals for transport applications.

Padlock seals are usually supplied as a completely plastic seal, shaped as a standard padlock would be. Technically they can be classed as a fixed length seal. They feature the same types of tamper-evident protection as variable length and fixed length have available – numbering, barcoding, and branding – but fit some different applications. The most common use for these seals is for airline duty-free trolleys. One reason for this is that plastic padlocks can be placed over a locking part as any metal padlock would be to secure, but do not require keys to open, they simply break off at their built in break point using hands or a small pair of wire cutters. They are secure due to the audit trail available as a result of the sequential numbering.

Meter seals are used with electric meters or gas meters or water meters and usually are molded in polycarbonate. The transparent body of the security seal means that the locking mechanism is visible and can provide clear indication of tampering. Meter seals can withstand exposure to sunlight and extreme weather and a wide range of temperatures. Designed for only a single use they are destroyed when removed. Some meter seals contain components which glow under ultraviolet light allowing the seal to be easily located in darkness. Meter security seals are client personalized with company logo, serial number, and barcodes laser printed on them without the possibility that the print will be erased accidentally or by theft access purpose.

Multipurpose seals

Special security tapes and labels have high bond-strength adhesives in combination with backing that are designed to fracture or delaminate under designated conditions to indicate premature attempts at opening. Custom printing, holograms, and security printing often assist in deterring and indicating tampering.
