The different types of security seals and their advantages

Security seals are mechanisms that make it possible to track goods by verifying in particular that they have not been damaged or that their containers have not been damaged, opened or contaminated. There are various types of security seals; here are the most common ones.

Plastic seals

If you want to buy plastic seals, you will have the choice between adjustable seals or fixed seals. As the name suggests, adjustable seals are adjustable according to the product they seal. They generally consist of a notched link that allows the length to be adjusted according to the application. These seals exist in various colors and are often equipped with a customizable tab that can receive a product name, a date or even a bar code for tracking. They are also particularly easy to install. Fixed seals have the same characteristics as adjustable seals, but it is impossible to control the length of the link. For example, they are used to secure containers that require fixing two seals of identical lengths. They are also very easy to install and durable.

Adhesive tapes and labels

Used by professionals, but also by individuals, adhesive strips and labels are devices that are sensitive to openings: they tear if handled. Thus, a box or a package closed with a seal such as an adhesive tape or label will not be inviolable, but whoever receives it will know at a glance whether it was opened or not during transport. This material can also be used during a move or a trip, to seal a suitcase, boxes, etc.

Metal seals

Metal seals are generally non-preformed cables that fray when cut. They have numerous advantages such as safety, versatility and solidity. Unlike plastic seals, they are not only intended to discourage malicious persons, they also make it possible to secure the contents of the moved item because they are very difficult to destroy or cut. These seals are particularly popular for sealing bags of bulk products, for example.

The padlocks

There are several types of padlocks. Some are very simple: they consist of a wire clasp and a plastic body. They can sometimes be reused, especially if they have not been personalized with a bar code or information engraved on it. Other padlocks are also equipped with an efficient security system.

The bolts

Bolts represent obstacles designed to secure high-value goods. They are made of a solid steel bolt that attaches to a molded plastic liner. So the bolts are made of two parts, male and female. All of these seals have different advantages. As a general rule, the more valuable the contents to be protected, the stronger the seal. This applies to physical goods, on the other hand, some seals will simply deter curious or malicious people from opening an envelope or a package for example. The seal therefore has several functions, it makes it possible to secure, to guarantee confidentiality, to guarantee confidentiality, to close and sometimes even to ensure follow-up thanks to a labeling and/or bar code system. Do you want to use seals in your business, but do not know which type to choose? Do not hesitate to ask for advice from a professional in the sector, who will be able to help you select the right equipment for your business. Each seal has its own characteristics, making the right choice means avoiding constraints and having better results.
