Overview
The JB-Brookfield JB-121 Film & Plastic Peel Strength Tester is an electronically actuated universal testing machine engineered for precise quantification of interfacial adhesion and delamination resistance in thin-film polymer systems. Designed around a servo-controlled electromechanical drive system, it applies controlled tensile loading to standardized peel configurations—including 90°, 180°, and T-peel geometries—enabling measurement of peel force (N), average peel strength (N/mm), and energy dissipation per unit width (J/m). Its architecture conforms to the fundamental principles of quasi-static mechanical testing under ISO 6722, ASTM D903, ASTM D1876 (T-peel), and ISO 8510-2, while meeting the metrological requirements specified in GB/T 16491–1996 for electronic universal testing machines. The system delivers high reproducibility across low-force regimes typical of flexible packaging, laminated films, pressure-sensitive adhesives, and medical device barrier layers.
Key Features
- Modular load cell configuration with selectable capacities: 200 N, 500 N, and 1000 N—optimized for sub-newton to multi-newton peel force resolution
- Five-range automatic force amplification switching ensures optimal signal-to-noise ratio across dynamic test profiles
- High-resolution displacement sensing (1/1000 mm) coupled with closed-loop speed control (1–250 mm/min) supports both standard and accelerated peel protocols
- Adjustable crosshead travel (450 mm effective stroke) and 320 mm test width accommodate industry-standard specimen fixtures and custom jigs
- Robust cast-aluminum frame with precision-ground guideways minimizes lateral deflection and maintains axial alignment during low-stiffness film testing
- Integrated overload protection and emergency stop circuitry comply with IEC 61000-6-2 electromagnetic compatibility and EN ISO 13857 safety standards
Sample Compatibility & Compliance
The JB-121 accommodates specimens ranging from 5 mm to 300 mm in width and up to 1 mm in total laminate thickness. It supports standardized grip types including pneumatic roller clamps, spring-loaded film jaws, and peel-specific fixed-angle fixtures for consistent bond-line separation. All mechanical components are constructed from corrosion-resistant anodized aluminum and stainless steel to ensure long-term dimensional stability in ambient laboratory environments. The instrument meets national metrological verification requirements per JJG 475–2018 (Verification Regulation for Electronic Universal Testing Machines) and is suitable for use in GLP-compliant quality control laboratories conducting routine adhesion validation per ISO 10993-18 (biocompatibility evaluation of medical device adhesives).
Software & Data Management
The JB-121 operates with JBTestSuite v3.x—a Windows-based control and analysis platform supporting real-time force-displacement curve acquisition at ≥100 Hz sampling rate. Software features include automated calculation of peak peel force, average peel strength, and standard deviation across user-defined test segments. Export formats include CSV, XLSX, and PDF reports with embedded metadata (operator ID, timestamp, environmental conditions, calibration traceability). Audit trail functionality logs all parameter modifications, test executions, and data exports in accordance with FDA 21 CFR Part 11 requirements when configured with user authentication and electronic signature modules.
Applications
- Quantitative assessment of adhesive bond integrity in food-grade laminated pouches (PET/AL/PE, BOPP/CPP)
- Evaluation of release liner adhesion for transdermal patches and diagnostic test strips
- Validation of thermal lamination strength in flexible printed electronics substrates
- Comparative peel performance testing of UV-curable and solvent-based acrylic adhesives
- Quality assurance of medical tape adhesion on synthetic skin simulants per ISO 10993-10
- Research into interfacial fracture mechanics of multilayer biodegradable films (PLA/PBAT blends)
FAQ
What peel test configurations does the JB-121 support?
The system is mechanically compatible with 90°, 180°, and T-peel fixtures; optional accessories include adjustable-angle peel arms and motorized peel angle actuators.
Is the load cell calibrated traceable to national standards?
Yes—each load cell ships with a certificate of calibration traceable to CNAS-accredited reference standards (equivalent to ISO/IEC 17025), with recalibration intervals recommended every 12 months or after 5,000 test cycles.
Can the JB-121 be integrated into an automated production line environment?
While designed primarily for lab-based QC, its RS-232 and Ethernet interfaces support SCADA-level integration via Modbus TCP or OPC UA protocols when paired with optional industrial I/O modules.
Does the software support statistical process control (SPC) charting?
JBTestSuite includes built-in X-bar/R chart generation, capability indices (Cp, Cpk), and trend analysis tools compliant with ISO 22514-2 for manufacturing process monitoring.
Are environmental condition sensors supported?
Optional temperature and humidity probes can be connected via USB or analog input channels, with environmental data time-synchronized to each test record.
