According to experts, tamper-evident security seals are crucial for ensuring the integrity of a package or product by providing a visual indication of any tampering. By using these seals, unauthorized access is deterred, and it becomes easier to identify and investigate any attempts at tampering.

The principal reason for using tamper evident seals is to ensure the integrity of the package that the seal is affixed to. They provide visual evidence of any attempt to open or manipulate that package. Ultimately, it discourages unauthorized opening or tampering.
Even a premier tamper evident seal is not a lock. Instead, the seal is typically designed to be used only once before being destroyed. If tamper evident security seal indicates that someone has attempted to open any packages, you can start an investigation to catch the violator, whether you discover the attempt or the recipients do.
They come in different types. You can even get a customized tamper evident seal printed with your logo. A tamper evident feature varies according to the type. Some have tampering indicators such as perforations or frangible materials that break or tear when the package is opened. Others have special adhesives that leave a residue or other visible evidence if the seal is removed. Still others use high-strength metals and require special tools to remove.
How to use tamper evident security seals
It's a straightforward process that generally involves applying the seal to a package or product in a specific way to ensure its effectiveness. How a security seal is used depends on the type, but here are the general steps for using one.
1. Apply the seal
To apply the seal, first make sure the surface you'll be sealing is clean and dry. Then, position the seal over the opening or access point that you want to secure. Press down firmly on the seal to activate any adhesive or locking mechanisms that are part of the seal. Some seals may require you to peel off a protective backing or other layer before applying.
2. Check the seal
Once the seal is applied, check to make sure it is securely in place and that any locking mechanisms have engaged. Verify that the seal is intact and that there are no signs of tampering or damage. Some seals may have additional features, such as unique identifiers or serial numbers, that can be used to verify authenticity.
3. Monitor the seal
Keep an eye on the seal over time to ensure that it remains intact and that there is no visible evidence of tampering or damage. If you notice any issues or concerns, take appropriate action to investigate and address them.
It's important to follow the instructions provided with the specific security seal you're using.
How to select the right seal
Consider your requirements and the features necessary to what you want to achieve. This will include multiple factors, such as:
Type of seal
Weigh the different types of security seals against each other, including labels, tapes, bags, and other forms, such as tamper evident seal stickers. This will involve consideration of your industry. A tamper evident seal for food isn't necessarily the best choice for tamper evident seals on foley catheters.
Level of security
You have several choices here, as you'll see below. If you need a high level of security, consider a bolt seal. Another way to go is with a seal that allows for customized information, such as a serialization tamper evident seal. Serialization is a critical part of supply chain security initiatives. A unique serial number is assigned to each package. This number is then recorded in a database, allowing manufacturers and consumers to track the package throughout its lifecycle.
Industry requirements
Does your industry have specific requirements for this range? For example, international freight transports often demand ISO 17712 certified high-security seal. U.S. regulations require tamper-resistant packaging to ensure the integrity of pharmaceutical packaging. A tamper evident seal bottle would qualify here.
Material
Tamper-evident seals can be made from plastic, metal or paper. Consider which material is best suited for your application, based on factors such as durability, environmental conditions, and the type of package you're sealing.
Application method
Application methods vary according to the type of tamper-evident seals you're using, from self-adhesive to bolting. Consider which method best suits your needs – do you want ease of applying the seal? Do you want it easily removed? Or is the application method not so much a priority as the security that the seal provides? These are points that only you can decide by balancing them against other considerations.
Cost
A tamper evident security seal can vary in cost, depending on the type, material, and features. Consider your budget and how much you're willing to spend on security measures, while also ensuring that the seal you choose is effective for your needs.
Overall, selecting the right seal requires careful consideration of your specific needs and the level of security you require. By choosing the right one, you can help to ensure the safety, integrity, and authenticity of your packages.
Security seal types
The International Organization for Standardization ISO 17712 classifies three types of security seals: Indicative, Security, and High.
Indicative seals
Class “I” indicative seals have a low breaking strength and are easily broken by hand or by using a simple snipping tool or shear. Most indicative seals are one-piece.
Narrow recess seal
This plastic seal is specially designed for applications that require a very slim seal. The padlock seal has an all-plastic design with an acetal jaw-locking mechanism. Easy and convenient, single-handed application. These are available in blue, green, orange, red, white and yellow.
Use for: Utility box meters, security documents and securing in-flight trolleys, ATM cassettes and other cart applications. Also suitable for banking and cash-in transit
Tamper evident label
Tamper evident label made of polyester is easily applied as a tamper-evident seal tape. The matte surface is suitable for writing and provided in die-cut pieces. Option available that doesn't leave behind residue. Another option: a tamper evident label that provides visual evidence by leaving a 'VOID' message to alert you to tampering.
Use for: Confidential documents and containers, gaming security, restricted medical packaging, computer and information technology products
Pull tight seals – smooth strap
Easy to apply and tighten to a desired diameter. Several seal types are available, including those with longer tags and with a tear-off tab for quick and easy removal. These seals have a polypropylene strap with a stainless-steel locking jaw and are also available with a barbed strap.
JawLock is a versatile seal designed for small strap diameters, making it ideal for securing items with a small aperture. The thin round and smooth strap has side tear-off functionality and includes a full-size tag with ample surface for codings. SegurLock and SmoothLock are user-friendly options featuring smooth straps with gripping prongs on the stem. TeraLock provides high-break strength with a stainless steel locking jaw and heat weld cap that helps enhance security.

High security seal
“H” class seals are constructed and manufactured of material such as metal or metal cable with the intent to delay intrusion. They can generally be removed with substantial bolt cutters or cable cutters.
Customs Trade Partnership Against Terrorism (CTPAT) is part of the U.S. Customs and Border Protection's (CBP) cargo enforcement strategy. This program is used by the CBP with the trade community to strengthen international supply chains and improve U.S. border security. CTPAT is solely a voluntary partnership program that recognizes that CBP can provide the highest level of cargo security only through close cooperation with stakeholders in the international supply chain. This includes importers, carriers, consolidators, licensed customs brokers, and manufacturers. CTPAT requires ISO 17712 “H” class seals.
Cable seals – metal body
Used worldwide to secure goods during import and export. These seals can secure goods for long periods of time. The non-preformed cable unravels when cut to prevent tampering. The steel cable can only be removed using a tool. Non-preformed galvanized steel aircraft cable with aluminum body. Compliant with ISO17712:2023 and CTPAT with cable diameters of 3.5mm and above.

Bolt seals
The insert and pin head keep the seal engaged on the application’s latch when the plastic cover is intentionally or accidentally removed. It has limited 180-degree rotation when engaged. These tamper evident seals prevent high-speed spinning attacks on the barrel. The bolt seal also features a label attachment.
Range includes different options, including coated and uncoated pins. The coated pin has an additional layer of paint that gives it an extra layer of protection from chips and damage. The bolt seal barrel is made from high-quality ABS material, giving it good impact resistance while also indicating evidence of tampering.
ISO 17712:2013 (coated pin option only) and CTPAT compliant.
Use for: Shipping containers, cargo containers, trucks, trailer vehicle doors and rail freights
Do seals really help?
Tamper-proof seals do not exist – remember, these are not locks. Tamper evident seals deter tampering, which makes them incredibly valuable for communicating the integrity and/or safety of your package. A tamper-evident seal on a container means that it is being monitored. This in turn gives customers confidence in what they’re buying. Without that sense of security that a seal inspection provides, customers would look elsewhere for their needs.
