Overview
The Labthink BLD-200N Electronic Peel Tester is a precision-engineered mechanical testing instrument designed for quantitative evaluation of interfacial adhesion strength in flexible laminated materials and pressure-sensitive adhesive (PSA) systems. It operates on the fundamental principle of controlled tensile separation—applying a defined peeling force at a fixed angle (typically 90° or 180° per standard protocols) to measure the resistance of an adhesive bond to delamination. This method conforms to established peel test mechanics described in ASTM D903 and ISO 8510-2, and is widely adopted in quality control laboratories for regulatory compliance, material development, and process validation across packaging, medical device, and industrial tape manufacturing sectors.
Key Features
- Microprocessor-based control system with LED digital display and intuitive PVC membrane keypad interface
- Four selectable load ranges (including optional 30 N, 50 N, 100 N, and standard 200 N configurations) to optimize resolution and accuracy across diverse specimen strengths
- Dual-test mode architecture: dedicated peel and tensile testing programs, each supporting seven calibrated speed settings (50–500 mm/min)
- Real-time statistical processing: automatic calculation and display of peak force, minimum force, and arithmetic mean over the selected test interval
- Integrated mechanical safeguards: overload protection, stroke limit switches, and auto-zero compensation to ensure repeatability and operator safety
- Onboard measurement reference scale for direct visual assessment of specimen elongation during tensile tests
- Standard RS232 serial interface and optional Ethernet port for seamless integration into local area networks (LAN), enabling centralized data logging and remote monitoring
- Thermal line printer included for immediate hard-copy output of test results, including date/time stamp, sample ID, test parameters, and statistical summary
Sample Compatibility & Compliance
The BLD-200N accommodates specimens up to 30 mm in width and 500 mm in maximum travel distance, making it suitable for standardized test strips cut from films, foils, laminates, coated papers, nonwovens, and medical-grade backing materials. Its mechanical design supports both 90° and 180° peel geometries using interchangeable fixture sets (e.g., rigid substrate clamps, roller fixtures, and guided peel arms). The instrument is validated against a comprehensive suite of Chinese national standards—including GB/T 2792 (peel strength of pressure-sensitive tapes), GB/T 2790 (adhesion of flexible materials to rigid substrates), GB/T 2791 (adhesion of flexible materials to flexible substrates), and GB/T 17200 (general principles for universal testing machines)—ensuring traceable performance in GLP-compliant environments. While not certified to ISO/IEC 17025, its Class 1 accuracy rating per GB/T 4743 aligns with routine QC requirements under ISO 9001 and IATF 16949 frameworks.
Software & Data Management
When paired with Labthink’s optional PC-based analysis software (sold separately), the BLD-200N supports advanced data acquisition, graphical force–displacement curve visualization, batch report generation, and user-defined pass/fail criteria. The software maintains full audit trails—including operator ID, calibration history, test parameter logs, and timestamped raw data—meeting documentation expectations for FDA 21 CFR Part 11 compliance when deployed with appropriate access controls and electronic signature modules. Raw data exports are available in CSV and XML formats for import into LIMS or ERP platforms. Network connectivity enables real-time synchronization of test records across multi-site facilities operating under unified quality management systems.
Applications
- Quantification of peel adhesion of medical transdermal patches, surgical tapes, and wound dressings per ISO 25537 and USP
- Evaluation of release liner adhesion loss in silicone-coated papers and fluoropolymer films
- Quality assurance of protective films used in electronics, automotive trim, and architectural glass applications
- Development and specification of hot-melt and solvent-based laminating adhesives in flexible packaging structures
- Validation of aging effects on PSA performance after accelerated thermal/humidity exposure per ASTM F1980
- Comparative assessment of surface energy modifications (e.g., corona treatment, plasma activation) on film substrates
FAQ
What peel angles does the BLD-200N support?
The instrument is configured for standard 90° and 180° peel tests using interchangeable fixture kits; custom angular setups require third-party tooling.
Can the BLD-200N perform loop tack or probe tack tests?
No—tack measurements require specialized geometry and dynamic loading profiles not supported by this static peel/tensile platform.
Is calibration certification included with shipment?
A factory-issued calibration report traceable to CNAS-accredited standards is provided; annual recalibration is recommended per ISO/IEC 17025 guidelines.
What safety certifications apply to the electrical system?
The unit complies with GB 4793.1 (equivalent to IEC 61010-1) for electrical safety in laboratory equipment.
Are custom夹具 (non-standard fixtures) available?
Yes—Labthink offers engineered fixtures for specialty substrates (e.g., foam-backed tapes, textured surfaces) upon request with lead-time and NRE considerations.
