Tamper Evident Bank Bags Today
Although banks and armored couriers have relied on traditional zipper money bags for decades, tamper evident bank bags offer features that often cannot be matched by the typical canvas bank bag.
Tamper evident bags are specifically designed to protect the integrity of the bag’s contents and alert you if someone has attempted to take anything from the bag. For example, many tamper evident bank bags have highly visible void messaging to indicate when a bag has been tampered with.
Recent advancements in tamper evident bags have made them a most cost-effective and efficient option for businesses that handle cash. Vault Process Certification (VPC) ensures consistency in performance, stronger plastics, lower weight and higher cost savings. For example, modern tamper evident bank bags that meet Vault Process Certification are manufactured to have thinner walls without compromising the strength of the plastic itself.
VPC-approved tamper evident bank bags are also able to withstand vigorous use in cash vault and armored courier environments. These tamper evident bags have a low slip level (or “coefficient of friction”) so that heavy cash bags can be thrown on pallets without sliding off or bursting on impact.
What Makes a Tamper Evident Bag?
Regardless of the industry, protecting cash deposits with tamper evident bags is critical to growth. Because cash is a high-risk asset constantly moving between retailers, banks and cash-in-transit companies, a security bank deposit bag is one of the most important lines of defense against thieves. Unlike traditional zipper money bags, locking security bags or canvas bank bags, today’s tamper evident bags have many security features to indicate if a bag has been opened or compromised in any way, either by a thief of opportunity or a professional.
The latest developments in tamper evident bags have made them more affordable and accessible to any business that handles cash while offering many tamper evident features.
Small Openings Prevention Unique to CONTROLTEK Tamper Evident Bank Bags
Tamper evident bank bags are typically sealed with a small flap with an adhesive that sticks to the bag to keep it closed. However, employees who want to save time and space for their organization will often fold the adhesive flap further down on a cash bag, unintentionally leaving an opening at the top of a cash bag, which can allow a thief to reach into the opening and take cash from the bag.
A triple-seal closure — as seen in our TripLOK bag, the most widely used tamper evident bank bag in the industry — makes it virtually impossible to leave a small opening in the bag that can be later exploited.
Freezing Attempt Detection
Experienced thieves know that drastic changes in temperature can break a basic tamper evident seal on a security bank deposit bag without damaging the bag. They typically use a can of compressed air to apply freezing cold air directly to the seal.
However, modern tamper evident bank bags are designed with this weakness in mind. In this type of tamper evident bag, the freezing temperature of the compressed air activates security ink that reveals a high-visibility message to signal a tampering attempt.
Heating Attempt Detection
Similar technology can also detect if a thief tries to open a tamper evident bag using heat. Along with freezing detection, today’s tamper evident bags often feature security ink that will activate when it detects heat being applied to the bag, revealing a red ink line or a high-visibility message to indicate that heat was used to open the bag.
Water and Saliva Detection
Using water or even saliva is another common method for thieves to try to defeat a tamper evident seal. Thieves who have internal access to security bank deposit bags, such as employees at a bank or cash-in-transit company, will often use their own saliva to weaken the seal of a tamper evident bag, preventing it from closing properly.
Tamper evident bags often have a security feature that uses water- and saliva-soluble inks to detect the use of fluids to tamper with the cash bag’s seal. The bag’s seal features a tamper evident message printed with the special ink, and fluid will smear the ink and indicate tampering.
Security Border and Microprinting
A common security feature in tamper evident bags is the use of microprinting along a security border. This feature uses a printed design along the borders of a bag, which can be cut open with a razor blade and resealed.
With the microprinting security feature, you can easily tell if a tamper evident bag was cut open and sealed back up because it is impossible to line up the tiny pattern of a microprinted security border after cutting it apart.
