General-Purpose Blue Film: Flame retardancy meets UL94 V-0 standard (tested on 2mm aluminum foil); Meets national standards for electrical performance (leakage current, puncture resistance, and resistivity); Maintains adhesion on battery folded edges at both room temperature and 80 °C without popping open; No adhesive residue when peeled off after 7 days at room temperature; High tape tack for strong adhesion.

High-Shear Blue Film: High shear strength and strong adhesion; maintains bonding under complex stress conditions; Superior electrical insulation compared to standard wrapping tapes, helping to isolate individual cell failures; 
Excellent aging resistance; reliably protects battery cells even in extreme and variable environments; Outstanding high-temperature shear and pull strength; remains stable under battery operating heat; Long open time for easier processing during production.

• Excellent high and low temperature resistance: Maintains adhesion without degradation, yellowing, or embrittlement in high-temperature environments (120–150°C)
• Remains crack-free and securely bonded at –40°C without lifting or warping
• Outstanding aging resistance: No performance degradation after 1500 hours under 85°C/85% RH conditions
• Strong chemical resistance: Effectively resists most chemical solvents and is not easily corroded
• Superior flame retardancy: Complies with UL94 VTM-0 flame-retardant standard
• Easy to use: Single activation with no rebound, no need for secondary activation, reducing process cost
