Tamper evident seals are mechanisms that make it possible to ensure the tracking of goods, in particular by verifying that they haven’t been damaged or that their containers haven’t been harmed, opened, or contaminated. There are different types of tamper evident seals; here are the most common ones.

Plastic seals

If you want to purchase plastic seals, you can choose from adjustable or fixed seals. They generally consist of a notched tie that lets you adjust the length depending on the application..

Fixed seals offer the same features as adjustable seals, but it’s impossible to control the length of the tie.

Adhesive tapes and labels

Used by professionals as well as individuals, adhesive tapes and labels are devices that are sensitive to openings: they tear if manipulated. A box or package sealed with an adhesive tape or label therefore won’t be inviolable, but the person who receives it will be able to tell at a glance whether or not it was opened during transport.


Metal seals: cables and bolts

Metal seals are usually cables or bolts. They have many benefits, such as security, versatility, and strength. They’re not only intended to discourage malicious people; they also make it possible to secure the contents of the item in transit, since they’re very hard to destroy or cut. These seals are particularly appreciated for the compliance of ISO17712: 2013 C-TPAT.

All these seals offer different advantages. As a general rule, the higher the value of the contents to be protected, the stronger the seal is. This applies to physical merchandise; on the other hand, certain seals will simply dissuade curious or malicious people from opening an envelope or a package, for example.
