EcoLOK4: 90% Post-Consumer Recycled Tamper-Evident Technology. The EcoLOK4 stands as the industry’s first and only tamper-evident bag manufactured with 90% post-consumer recycled (PCR) film, certified by GreenCircle. This significant attribute allows your organization to reduce its carbon footprint and environmental burden without sacrificing the security or durability required for cash-in-transit. Beyond its sustainable composition, the EcoLOK4 features Vault Process Certified (VPC) film. This film contains unique additives that allow for thinner walls without sacrificing the strength of thicker bags. The result is a lighter bag that reduces shipping weight and costs while remaining durable enough to withstand the rigors of cash vault and armored truck environments. These bags are specifically formulated so they can be palletized without the risk of sliding and bursting. Security and Operational Efficiency. The EcoLOK4 is engineered to deter theft and provide immediate evidence of tampering through several advanced features: Unrivaled Tamper-Evident Tape: The adhesive spans the entire width of the bag and uses a fold-over closure to ensure there are no vulnerable openings. Complete Temperature Protection: The seal displays a "void" message at temperatures ranging from $-130F (-90C) to +176F (+80C). Detection Mechanisms: Tampering via heat triggers a visible red line, while extreme cold causes the seal to disintegrate. Additionally, the security message smears upon exposure to fluids or chemicals. Cash Visibility: The bags feature multiple large serials and GS1 compliant barcodes for easy scanning, allowing for greater transparency and efficiency throughout the entire cash cycle.
