What is the security bag seal tape?

Security bag seal tape is special types of sealing tapes or sealing designs with anti-pulling and anti-counterfeiting functions. They are mainly used for sealing plastic bags, envelopes, or cartons. When they are illegally opened or torn off, they will leave obvious marks (such as displaying words like "VOID", "Opened", etc. or damaging patterns), thereby preventing the contents from being replaced, stolen, or tampered with. They are commonly used in secure packaging of important documents, cash, evidence, etc.

Main Features of the security bag seal tape :

Technical principle (tear-off with remaining characters): The seal is made with a special high-strength adhesive. When exposed to heat, cold, or torn, the surface of the tape will display the pre-set anti-counterfeiting characters (such as "VOID", "OPENED", etc.) or damaged patterns, and these marks cannot be restored. One-time use: It is "anti-counterfeit". Once torn, it cannot be reattached and reused, effectively ensuring the integrity of the goods.

The application of the security bag seal tape:

This kind of seal is usually applied to security bags, express bags, etc., to ensure the safety of valuable items,  evidence, confidential documents, etc. during transportation and storage.
