The GBPI GBH-2 is a premier laboratory-grade electronic tensile testing machine engineered for precise tensile, elongation, peel, tear, puncture, and shear strength characterization of flexible packaging films, laminated foils, medical packaging, self-adhesive tapes, and polymeric elastomers. Built in strict conformance with leading international standards including ASTM D882, ASTM D828, ASTM D1938, ASTM D3330, ASTM F88, ISO 37, and JIS P8113, this versatile single-column universal mechanical tester provides quality inspection facilities and research institutions with uncompromising analytical precision.
Mechanical stress verification is paramount to guaranteeing the physical integrity of packaging during high-speed vertical form-fill-seal (VFFS) converting, shipping vibrations, and warehouse stacking. Operating as a multi-functional electronic tensile testing machine, the GBPI GBH-2 utilizes a precision AC servo motor coupled to a zero-backlash preloaded ball screw drive system, delivering vibration-free crosshead translation across stepless speeds from 0 to 500 mm/min. Interchangeable high-stability S-beam load cells record instantaneous tensile and compressive forces with Class 0.5 metrological accuracy (±0.5% of displayed value), while an optical rotary encoder continuously tracks crosshead displacement.
Multi-Mode Test Protocols & Pneumatic Grips
The GBH-2 incorporates pre-configured testing modules covering 180° and 90° peel adhesion (ASTM D3330), trouser tear resistance (ASTM D1938), heat seal strength of flexible barriers (ASTM F88), puncture resistance of medical films, and standard tensile stress-strain profiling (ASTM D882). Operators can equip the crosshead with pneumatic flat-face grips, rubber-coated eccentric clamps, or wedge fixtures to eliminate sample slippage and premature jaw breaks.
Dual Touchscreen & Workstation Software Architecture
Featuring an articulated color touchscreen terminal on the instrument base alongside bidirectional PC USB connectivity, technicians can initiate routine quality checks directly on the unit or utilize the comprehensive PC software for advanced Young's modulus derivation, yield point calculation, and multi-curve statistical overlays.
The software suite features automated safety limit stops, overload protection circuitry, multi-tier user authority controls, and automated PDF test report export compliant with FDA 21 CFR Part 11 and pharmaceutical GMP audit trails.
