To improve aerodynamics

To deter theft and maintain cargo security

The purpose of a trailer seal is primarily to deter theft and maintain cargo security. When a trailer is sealed, it provides a physical barrier that indicates whether the cargo has been tampered with or accessed without authorization. This is especially important in the transportation of valuable or sensitive goods, as a seal can help ensure that the cargo remains intact during transit.

By using a trailer seal, drivers and freight companies can help to secure their cargo against theft and unauthorized handling, which is crucial for maintaining the integrity of the shipment. If the seal is broken, it also provides clear evidence that the security of the shipment may have been compromised, prompting further investigation. Overall, the security function of the trailer seal plays a vital role in the logistics and transportation industry.
