Pull Tight Seals are among the most versatile security seals offered by Navacqs. Available in various designs, including smooth, serrated, and flat tails, these seals are easy to apply and can be fully tightened to ensure a secure closure. Once removed, they cannot be reused. Due to their design variations, they are suitable for both light and heavy-duty applications, from postal shipments to freight transport and medical use.
Pull Tight Seals are used to detect unauthorized access to containers, fire extinguishers, medical kits, and transport equipment. They are classified as indicative seals, meaning they do not serve as a physical barrier but clearly show whether a seal has been broken. Depending on the intended application, seals with either high or low breaking strength can be selected. This ensures an appropriate solution for every situation, whether the focus is on security, traceability, or access control.
Every Pull Tight Seal from Navacqs is unique, featuring a combination of a company logo or custom imprint and a consecutive serial number. Each imprint is produced only once, preventing duplication or reuse. Both Navacqs and the manufacturer guarantee the exclusivity of each marking, ensuring the seal remains tamper-evident, reliable, and traceable.
Pull Tight Seals belong to the category of indicative seals. They signal whether an object has been opened but are not designed to resist forced entry. Their purpose is to indicate tampering rather than to block access. This makes them ideal for situations requiring quick inspection and verification, such as in transportation, logistics, and healthcare environments, where visibility and efficiency are key.
The breaking strength of Pull Tight Seals ranges from 4 to 40 kg. Seals with lower strength are ideal for emergency applications such as fire hoses and medical devices, as they can be broken by hand. Stronger seals (10–25 kg) provide greater resistance and are often used on trucks, containers, barrels, and roll cages. The appropriate breaking strength depends on the required level of control and the specific application.
Navacqs offers Pull Tight Seals with different tail types to meet diverse operational needs. Smooth tails are ideal where snagging must be avoided. Serrated tails, also known as rat-tail seals, provide extra grip when tightening. Flat tails combine strength with ease of use, making them suitable for heavier applications. The type of tail affects both handling comfort and the overall breaking strength of the seal.
Pull Tight Seals are used in a wide range of industries and applications. They are suitable for securing trucks, IBC containers, mailbags, collection boxes, and medical equipment. In warehouses, logistics operations, transport, and healthcare settings, they allow for fast and visible tamper detection. With their diverse designs and strength levels, there is always a suitable seal available to meet specific user or environmental requirements.
A pull-tight seal is a plastic seal that you insert through an opening and pull tight. Once closed, it cannot be reopened without visible damage. It's used to indicate whether something has been opened, not to physically block access. Pull-tight seals are also known as pull-through seals.
That depends on how strong the seal needs to be. For truck doors that move and pull on the seal during transport, choose a seal with a minimum breaking strength of 22 kg, such as the Heavy Duty Pull Tight Seal. For lighter applications, or when the recipient needs to be able to remove the seal by hand, a Medium Duty Pull Tight Seal with a breaking strength of 12 kg is the better choice.
Breaking strength is the force needed to break a seal, expressed in kilograms. A low breaking strength means the seal can be broken by hand, which is useful for emergency applications. Seals up to around 15 kg can be broken by hand, although 12 to 15 kg does require some force. From 22 kg upward, cutters or cable shears are needed. Breaking strength is determined by the thickness of the seal tail and the material of the locking mechanism.
A smooth tail slides easily through narrow openings without catching. That's useful for closures with limited space, such as tanker trucks and IBCs. A serrated tail, also called a rat tail, has ridges that provide extra grip when pulling it tight. This type is more commonly used on bags and big bags, where the seal needs to be pulled taut.
Yes. Most pull-tight seals can be personalized with your own logo, company name or barcode, combined with a unique sequential number. The minimum order quantity varies per product and is typically between 1,000 and 5,000 pieces. Lead time for personalized orders ranges from one to ten weeks.
An indicative seal such as a pull-tight seal shows whether something has been opened, but doesn't form a physical barrier. With tools or enough force, the seal can be broken. A high security seal is more heavily built, has a breaking strength from 1,000 kg, and complies with the ISO 17712:2013 standard. This type is mandatory for international container transport and can only be cut with bolt cutters.
For medical equipment and AEDs, use a seal with a low breaking strength that can be broken by hand immediately. In an emergency, the seal must not cause any delay. The Light Duty Pull Tight Seal, with a breaking strength of 6 to 7 kg, is suitable for this. When the seal also needs to be removable without any force, choose a variant with a tear strip, such as the MPT-TA.
