Whether you are looking for transporting or storing the items, it is important to ensure the integrity of the package. No wonder tamper evident bags have become a reliable solution to address this concern.

You must have come across these bags while handling cash at bank or ordering take-away food.

These bags provide visible evidence of tampering or unauthorized access, assuring both businesses and consumers of the safety and security of their packaged goods.

If you are new to these bags and wonder how you can use them for your business, this article will guide you on features, benefits, and applications of tamper-evident bags so that you can make an informed choice.


Tamper-evident bags come equipped with a range of features designed to prevent tampering and provide clear indications of any unauthorized access. Here are some key features:

Unique Closure Systems:

Tamper-evident bags utilize various closure systems, such as tamper-evident adhesive seals, security tapes, or locking mechanisms. These closures are designed to be secure and difficult to tamper with, ensuring that any attempt at unauthorized access is evident.

Void Labels or Tapes:

Many tamper-evident bags incorporate void labels or tapes. When someone attempts to open the bag, the label or tape will leave a visible “VOID” message, indicating that tampering has occurred. This feature acts as a deterrent and alerts both the sender and the recipient to potential security breaches.

Sequential Numbering:

Tamper-evident bags often feature sequential numbering or barcoding. This helps in tracking and tracing the bags, providing an additional layer of security and accountability.


Tamper-evident bags offer several significant benefits that contribute to safe and secure packaging:


The presence of tamper-evident features on packaging acts as a deterrent to potential tampering. Knowing that a package is protected by a tamper-evident bag can discourage unauthorized access attempts, thereby reducing the risk of theft, contamination, or tampering.

Businesses can ship their products with confidence, knowing that the tamper-evident bags provide an added layer of protection. Similarly, consumers can trust that the products they receive are in the same condition as when they left the sender.

Restaurants, catering services, and food manufacturers rely on these bags to ensure that the food products they deliver to consumers are in the same condition as when they were packaged, thus building trust and confidence in their brands.

Evidence Handling and Forensics:

Law enforcement agencies, forensic laboratories, and legal institutions utilize tamper-evident bags for secure evidence handling and storage. These evidence bags provide a chain of custody, ensuring that evidence remains intact and uncontaminated throughout the investigative process.
