Overview
The Labthink XLW(PC) Advanced Electronic Peel & Tensile Tester is a microprocessor-controlled universal testing system engineered for high-precision mechanical characterization of flexible packaging materials and pressure-sensitive adhesives. Based on the fundamental principles of uniaxial tensile loading and controlled peel separation, the instrument applies calibrated force through dual-grip motion to quantify key performance parameters—including peel adhesion (180° and 90°), tensile strength, elongation at break, tear resistance, puncture force, seal strength, and deformation behavior—under standardized test conditions. Its modular architecture supports both static and dynamic mechanical assessments in accordance with internationally recognized methodologies, making it suitable for routine quality control, R&D validation, and regulatory compliance testing in packaging, medical device, adhesive, and consumer product laboratories.
Key Features
- 0.5-class accuracy per ISO 7500-1 and ASTM E4, ensuring traceable, repeatable force measurement across the full load range (50 N to 1000 N).
- Seven pre-programmed test modes: tensile, 180° peel, 90° peel, tear (Elmendorf & trouser), seal strength, puncture, and shear—each configurable via intuitive menu-driven interface.
- Seven discrete test speeds (50–500 mm/min), enabling precise replication of industry-standard protocols such as ASTM F88 (seal strength), ASTM D3330 (peel adhesion), and ISO 37 (tensile properties of rubber).
- 1000 mm stroke length accommodates high-elongation substrates—including elastomeric films, hydrocolloid dressings, and stretchable protective laminates—without mechanical interference.
- Modular grip system with standard 30 mm parallel-jaw clamps; optional 50 mm grips and floating-roll fixtures available for low-tack or highly compliant specimens.
- Integrated safety architecture: programmable end-point limit switches, overload cutoff, automatic return-to-start, and power-loss memory retention.
- Large LCD display with PVC membrane keypad enables stand-alone operation without external computing hardware.
Sample Compatibility & Compliance
The XLW(PC) is validated for use with thin-film polymers (e.g., LDPE, PET, BOPP, CPP), pressure-sensitive adhesive tapes, medical transdermal patches, protective surface films (e.g., PET-based screen protectors), laminated pouches, aluminum foil composites, nonwovens, and paper-based packaging substrates. It meets essential requirements of ISO/IEC 17025 for test method validation and supports audit-ready documentation when paired with Labthink’s Lystem™ Laboratory Data Management System. All test routines align with mandatory clauses of FDA 21 CFR Part 11 (electronic records and signatures) when used with configured software modules, and support GLP/GMP-compliant workflows including user access control, electronic audit trails, and report versioning.
Software & Data Management
The proprietary Labthink testing software provides real-time force-displacement curve visualization, automatic peak detection, modulus calculation, and statistical analysis across multi-sample batches. Functions include group-wise mean/SD/COV computation, overlay comparison of up to eight curves, pass/fail threshold setting per ASTM or internal SOP, and export of raw data in CSV, XML, and PDF formats. Integration with Lystem™ enables centralized storage, cross-instrument result harmonization, role-based reporting permissions, and automated generation of IQ/OQ documentation packages. All software modules comply with 21 CFR Part 11 Annex 11 requirements for electronic data integrity.
Applications
- Quantification of initial tack and holding power of protective films used in electronics manufacturing.
- Validation of peel strength consistency for sterile barrier packaging per ISO 11607-2.
- Tensile property verification of biodegradable food packaging films against GB/T 1040.3 and ASTM D882.
- Seal integrity assessment of medical pouches under accelerated aging conditions.
- Adhesive bond durability evaluation for wearable sensor substrates subjected to cyclic flexing.
- Quality release testing of label facestocks and liner combinations per PSTC-101 and FINAT FTM 1.
- Comparative analysis of hot-melt vs. acrylic PSA performance on low-energy surfaces (e.g., PP, PE).
FAQ
What standards does the XLW(PC) support for peel adhesion testing?
ASTM D3330, ASTM F904, GB/T 2790, GB/T 2792, ISO 8510-2, and JIS Z 0237.
Can the instrument perform both tensile and peel tests without hardware modification?
Yes—the dual-grip design and software-selectable test modes allow seamless switching between tensile, 180° peel, 90° peel, and other mechanical protocols using only software configuration.
Is calibration traceable to national metrology institutes?
Yes—Labthink provides factory calibration certificates traceable to CNAS-accredited reference standards; optional UKAS/NIST-traceable calibration kits are available upon request.
What data security features are included for regulated environments?
Role-based user authentication, electronic signature capture, immutable audit logs, and encrypted database storage—all compliant with 21 CFR Part 11 and EU Annex 11.
Does the system support custom test methods beyond preloaded standards?
Yes—advanced users may define custom ramp rates, dwell times, multi-step profiles, and pass/fail logic via the software’s method editor module.
