Simple to install and easy to use, the Demetra seal has been designed to be adjusted easily and broken quickly. This plastic stem security seal is perfect for situations where the plastic seal needs to be changed regularly or broken manually.
A temporary seal that’s easy to remove
The Demetra recyclable plastic stem security seal has a low tensile strength (less than 4 Kn). This weakness allows you to break the plastic seal immediately if necessary, with a strong manual pull. This intended fragility is combined with a 160 mm notched stem to prevent any partial opening. This seal is the ideal choice if you require frequent seal changes.
The Demetra seal features the Pull Tite progressive tightening technology.
Progressive tightening plastic seals are divided into two types: Pull-Up, which are very strong, and Pull-Tite, which are less resistant:
- Pull-Up progressive tightening seal: Impossible to open by hand, which is why we offer an optional easy-open feature.
- Pull-Tite progressive tightening seal: Used when security must be ensured but manual opening is required if needed.
We have also equipped this security seal with an easy-open feature to make opening even easier.

How to use the Demetra security seal?
Like padlocks, seals also have different closing methods. Some seal from the front, others from the back, or even with a lead seal.
The Demetra security seal is one of those that seal from the front. Simply hold the head of the seal firmly in one hand and the stem in the other.
A simple pull, once inserted into the metal locking mechanism, will engage the tightening of the notched stem.
To break the seal, you have three options:
- Manually: as this is a thin-stem security seal, breaking it manually requires a sharp pull;
- Easy-open: simply pull on the tab and tear it;
- With scissors: a clean cut.
It is recommended to customize the seal with a serial number to further ensure the security and identification of your asset. If someone breaks or replaces the seal, it will be easier to detect theft or tampering.
Note that our seals are equipped with a unique numbering for each one, as well as the mention "sealed" to ensure optimal and maximum security!
The recyclable plastic Demetra security seal: is it customizable?
At SBE Direct, we place great importance on customer satisfaction. We believe this comes from products that reflect your image, like your company. With this in mind, we wanted customization to be as complete as possible.

Customization by laser printing (note that this type of printing is exclusively in black) ensures exceptional precision. We chose this printing method to guarantee durability, resistance in all conditions, and very high quality.
It is essential that your text fits within the customization area on the seal head. In our case, the printing area is 33x19mm.
You can include anything you want to appear on the seal head (green area in the diagrams), such as:
- A logo,
- A serial number,
- A barcode,
- A QR code.
What is a security seal?
There are many types of seals for different uses. These uses directly affect the shape, material, or stem of the seal. A security seal is therefore fundamentally different from a warranty seal.
The difference between these two types of seals lies in the intended use. Securing a product or asset is different from ensuring its authenticity. Before buying a seal, ask yourself: What will I use it for?
Here, as a security seal, its primary purpose is to guarantee the security of products or assets and to prevent possible fraud, tampering, or theft.
Security seals offer many advantages such as security, versatility, and strength. They are designed to deter malicious acts and also secure the contents of transported items. These seals are considered indicative seals (such as plastic ones) that can be broken manually with force.
For more details on the different types of seals, we have written an article on: Which security seal for which use?
