Whether you're transporting cash, sensitive documents or banking supplies, we have the most secure and cost-effective locking bank bag ever made. The close-tolerant metal zipper is next to impossible to reseal if a breach is attempted. This security option is perfect for transporting high-value items. In addition, all bags are constructed with a traditional fabric outer layer, as well as a carbon fire-resistant liner and inner layer of 70-denier nylon. When exposed to intense heat or flame, the multi-layer fibers will carbonize and expand, eliminating any oxygen content within the fabric. Our lightweight, durable, and economical bag improves efficiency and generates considerable savings for thousands of financial and retail institutions around the world.
