Description
Numbered Security Tape
Numbered Security Tape is a robust, tamper-evident sealing solution designed for secure packaging, shipment integrity, and traceability. Featuring sequential numbering, each application can be uniquely identified, helping to deter tampering and simplify auditing across logistics, warehousing, and high-value distribution environments.
Manufactured from high-quality BOPP (biaxially oriented polypropylene) film, the tape offers a balance of strength and flexibility. Each roll has a material width of 50.8mm (2”) and a roll length of 50m (164.04ft), with a 76mm (3”) core diameter to ensure compatibility with standard dispensers. The film thickness is approximately 50 microns (0.00196”), contributing to its durability while maintaining ease of application.
Performance characteristics are engineered for demanding conditions. Tensile strength reaches 210 MN/m² in the machine direction (MD) and 175 MN/m² in the transverse direction (TD), measured in accordance with ASTM D882 at 50%/min. Elongation at break is 85% (MD) and 105% (TD), providing flexibility and resistance to splitting under stress.
The tape uses a formulated hot melt adhesive system with a coating weight of 40–60 gsm (approximately 40–60 microns / 1.57–2.36 thou). This ensures excellent initial tack and long-term adhesion. Peel adhesion values are 35 N/25mm after 20 minutes and 37 N/25mm after 24 hours when tested on glass, demonstrating consistent bond strength over time. Tack strength reaches 60 N/25mm, ensuring quick and secure adhesion upon application.
Thermal and shear performance further enhance reliability. The adhesive has a softening point of 92°C (197.6°F) and a SAFT (Shear Adhesion Failure Temperature) of 59°C (138.9°F). Shear resistance is rated at 3 days (25mm x 25mm at 23°C on glass) and 1.5 hours (25mm x 25mm at 40°C on steel), indicating strong holding power under both ambient and elevated temperatures.
Combining high-performance materials with clear tamper evidence, Numbered Security Tape delivers dependable sealing, improved security, and full traceability throughout the supply chain.
