We have come a long way from the seals made by the ancient Pharaohs and kings to protect their belongings.
In the modern era, we have a huge variety of this low-cost tool providing us great value.
You can group all of the seals in six basic designs, they are-

There are many subcategories of these security seals. They are all used for different purposes. Let’s dig deep into the features to know which one is suitable for what job.
Security Seal Features
To understand the functionality of security seals, you first have to be well-acquainted with the individual properties of these tools. While discussing the characteristics remember that specification of the features can vary vastly in different types of seals.
Let’s not waste any more words and dive into the features right away.
Strength: The strength of a seal has to be approved by testing laboratories. Laboratories will verify a seal if it matches with Federal Specification FF-S-2738A: “Seals, Antipilferage” and Amendment 1 on “Mechanical Seal Design, Test and Strength Parameters” to ISO 17712 “Freight Containers.”
A security seal should be able to take 1000-2000 KG pressure. Other security seals like metal indication seals and cable seals can take anywhere from 120-400KG.
Tamper resistance: Wire, strap, cable, and bolt seals will resist for 10 to 30 seconds. Padlock seals will withstand for 15 to 60 seconds. They might also require some special tools to open. On the other hand, cinches will take 15 seconds to tamper.
Tamper indication: A tampered seal should scream out at first sight that it has been messed with. So, visual indications are the best. Some highly protective seals have low tampering marks. You need to have a sharp eye for those types.
Built material: The conventional materials for seals are plastic, aluminum, steel, polypropylene.
Plastic security seal manufacturers are currently ruling the market as those seals are now widely used in the consumer market. Aluminum seals are easy to handle, and steel gives you better protection.
Cost-effectiveness: This is the primary reason for which the seals were first popularized. They have to be cost-effective in both manufacturing and recycling. Their maintenance and inspection cost of these tools also have to be less. Though, for DoD application, the use should not be overruled by the cost.
Size and shape: It largely depends on the seal's use. You have dimensions that are good for ship containers and others for your groceries. However, they should have enough space on their body so that you can put a bar code or other information.
Generally, seals should have a length between 80mm to 100mm, and their average thickness should be around 1mm to 2.5mm. But you will find many other sizes in the market.
Installation: The installation process has to be fast, easy and comfortable. It should be easily understandable. An average person should be able to install it in about 10 seconds.
Exclusivity: Seals should be marked with individual numbers so they can eliminate or at least decrease the risk of seal counterfeiting. In case, that you have your own marking system, the seal needs to have the space to hold your marking.
Easy inspection: The design of the seal should lessen the time spent on inspection. You should not be spending a lot of time training your personnel either.
Environment-friendly: Plastic is the big villain in the twenty-first century. So, if you care about the future world, you might want to choose from the reusable seals. A plastic seal manufacturer should always make their seals reusable.
How Do The Work
We have told you before that there are several seal designs. With those different designs come different styles of locking systems. Here are each of their working methods.
Wire seals: The metal wire goes in the clip and tightens the grip. The clip locks on to the wire which is irreversible.
Padlock seals: These have a curved wire ending which goes into the plastic housing. Then the wire locks on to the housing to give you a strong seal.
Strap seal: It is a plastic strap that has a textured hole in the bottom. The top end goes into the bottom hole and locks on. You will be able to adjust the size of the grip.
Cable security seal: It works similar to the strap seal. Instead of having a plastic strap it has a metal wire. The bottom is also more robust than strap seals.
Bolt seal: This design works like plastic container seals. There is a metal head and a plastic container. You break them apart and push the metal head in the container. Thus, it will give you a firm grip.
Pull-up seal: It is also similar to strap style seals. Here you will find a spring latching mechanism that gives you a tight hold.
•Cost effective: security seals are very cost effective. You might not notice that if you have never seen the previous methods. Plastic seals cost a meager amount of money for increased value.
•Easy to install: They are very easy to install and control. If you are organized, you will have no problem with these locks.
•Adjustable grip size: Here, you will be able to adjust the size of the grip you want from your seal. It is something that you can’t do with other locks.
•This will not solve security problems: This device is not meant to give you total security. It’s your primary defense against security problems. This also gives you a warning of probable security issues.
•Requires protocols: Using seals requires personnel training, documentation, maintenance, checking and other services that drive the cost up.
•Inevitable problems with plastic: Most of the seals made for consumer use is made of plastic. No matter how hard you try, some of the plastic will make its way to the ocean.
Was that a lot for you?
Keep in mind all six seal types and read the features carefully. And, always choose your seal according to your use. Each of them has a different purpose.
