Advantages of Shipping Container Bolts
Securit
The bolt seal design effectively prevents unauthorized opening of the container during transportation and reduces the risk of cargo theft or tampering. This high security container bolt seal plays an important role in preventing cargo loss.
Waterproof And Dustproof
A high-quality bolt sealing system can effectively prevent moisture and dust from entering the container, protecting the cargo inside from moisture and contamination, which is especially crucial for perishable and sensitive cargo.
Durability
High-strength container bolt seals are made of high-strength materials (such as alloy steel), which have good durability and impact resistance. They can withstand various external forces during transportation, ensuring that they are not easily damaged after long-term use.
Easy To Operate
The design of bolt seals is usually simple and easy to use, allowing operators to quickly open and close containers, improving loading and unloading efficiency and reducing cargo turnover time.
Economical
Bolt sealing can reduce overall shipping costs by reducing cargo loss and increasing shipping efficiency. Although the initial investment may be higher, it can bring economic benefits in the long run.
Features of Rfid Seals
RFID technology increases security by preventing unauthorised opening or modification of the seal or product.
Tags help you track your assets quickly and accurately. This streamlines your inventory management and logistics processes.

Key Components of Rfid Seals
Tags
Passive devices with a microchip and antenna, attached to items like products or assets. Powered by RFID readers' radio waves.
Readers
Devices (fixed or handheld) that send and receive signals from tags, enabling fast data capture and bulk tag reading.
Record or confirm the correct serial number for the bolt seal. Since each seal has a unique tracking number, it is important that the correct individual seal is used and recorded.
Separate the bolt from the cap. Each bolt seal has two parts: the plastic-topped metal bolt portion and the cap. These two parts come connected together by a piece of thin plastic designed to be broken apart by hand before application.
Insert the bolt through the door latch. Each container style may have a slightly different latch setup, but there will be two metal components with holes that line up when the door is closed designed to place a bolt through.
Apply the cap. Push the cap onto the metal end of the bolt once it is in place. Caps are designed to be able to be applied easily by hand, but not removed.

Application of Rfid Seals
Food sector
Are used mainly as strap seals for hams for hams and shoulders, becoming a standard for quality assurance and traceability in the sector.
Retail sector
Used in wholesale trade in distribution warehouses, but also in retail. This model is also incorporated into the order processing of e-commerce or online sales sites.
Financial sector
The transport of cash and confidential documentation requires exhaustive monitoring of the merchandise, a process which has been simplified and secured by RFID applications.
Logistics sector and land transport
Are used to ensure the transport and traceability of containers, cages or other means of transport of goods.
