Security seals used in air transportation are particularly important for ensuring cargo and passenger security. These seals protect the integrity of the items carried and prevent unauthorized access or theft attempts. The main types and uses of security seals are as follows:
 
Plastic Security Seals: Plastic seals are widely used in baggage, cargo containers or airport operations. These seals are usually single-use and leave a mark by breaking or cutting when opened.
 
Metal Security Seals: Metal seals are preferred in cargo containers that require high security because they are more robust and durable. They are especially used in international cargo transportation.
 
Padlock Security Seals: Locked security seals designed with keys or combined codes are frequently preferred in valuable cargo transportation. These seals can be reusable and make unauthorized opening difficult.
 
Electronic Security Seals: These seals are equipped with electronic systems such as RFID (Radio Frequency Identification) technology and provide digital tracking. They can create an alarm or track their movements when opened.
 
Lead Security Seals: Lead seals are used especially in customs transactions and in situations requiring high security. They are physically very durable and leave a mark when the seal is opened.
 
Each of these seals is selected according to a certain level of security and is used in accordance with the procedures determined to ensure security during the transportation process.
