Overview
The TMI 80-91 Peel Adhesion Tester is a precision-engineered mechanical testing instrument designed for quantitative measurement of interfacial bond strength between two adhered materials under controlled peeling conditions. Operating on the principle of tensile force transduction during angular separation—typically at standardized peel angles of 90°, 135°, or 180°—the system delivers repeatable, traceable adhesion data critical for quality assurance in flexible packaging, label manufacturing, printed electronics, and laminated substrate development. Its modular load cell architecture supports full-scale measurement up to 11,399 g (≈111.8 N), enabling evaluation of both low-tack pressure-sensitive adhesives and high-strength structural laminates. The instrument complies with internationally recognized test methodologies including ASTM D903, ASTM D3330, PSTC-101, and ISO 8510-2, ensuring data compatibility across global R&D, QC, and regulatory reporting environments.
Key Features
- Motor-driven crosshead with programmable speed control from 30.48 to 4046 cm/min, supporting both static and dynamic peel rate protocols required by industry standards.
- Integrated touchscreen interface for real-time test setup, parameter validation, and immediate visual feedback—eliminating dependency on external PCs during routine operation.
- Modular load cell configuration with optional calibration kits; factory-traceable calibration documentation conforms to ISO 9000 quality management system requirements.
- Automated peak detection algorithm identifies local maxima within force-time curves, enabling precise localization and statistical characterization of adhesive failure modes (e.g., cohesive vs. interfacial).
- User-definable test methods—including dwell time, pre-peel tension, angle selection, and stop criteria—stored as reusable templates to ensure method consistency across shifts and operators.
- Onboard statistical engine computes mean, standard deviation, maximum/minimum values, and coefficient of variation (CV%) per test series, supporting SPC-based process monitoring.
Sample Compatibility & Compliance
The 80-91 accommodates specimens up to 5 cm wide and 30.48 cm long, making it suitable for standard strip specimens used in tape, film, foil, and coated-paper testing. Its rigid frame and low-inertia drive train minimize parasitic vibration, ensuring high signal-to-noise ratio during low-force measurements (<100 g). The system supports compliance with FDA-regulated environments through audit-ready electronic records when paired with validated PC software (optional). All mechanical and firmware components are manufactured in the United States and certified to meet CE marking requirements for electromagnetic compatibility (EMC) and low-voltage directive (LVD) standards. Routine verification procedures align with ISO/IEC 17025 guidelines for testing laboratories.
Software & Data Management
When operated with TMI’s proprietary Windows-based software suite (sold separately), the 80-91 enables GLP/GMP-compliant data handling: user access levels, electronic signatures, audit trails, and 21 CFR Part 11–ready report generation. Raw force-time datasets export in CSV and XML formats for integration into LIMS or statistical analysis platforms (e.g., JMP, Minitab). Report templates adhere to internal SOPs or external regulatory formatting—customizable headers, pass/fail thresholds, graphical overlays (e.g., superimposed curves), and annotated failure event markers. All calibration events, firmware updates, and user actions are timestamped and logged with immutable metadata.
Applications
- Quantitative validation of hot-melt, acrylic, rubber-based, and silicone PSAs in label stock and medical tape production.
- Comparative assessment of seal integrity in heat-sealed pouches, blister packs, and sterile barrier systems per ASTM F88.
- Development and release testing of release liners, transfer tapes, and die-cut adhesive components.
- Quality surveillance of gravure- and flexo-printed substrates where ink adhesion affects downstream lamination yield.
- Root-cause analysis of delamination in multilayer films used in food and pharmaceutical packaging.
FAQ
What peel angles does the 80-91 support, and how are they selected?
The instrument provides fixed-angle fixtures for 90°, 135°, and 180° peel configurations. Angle selection is mechanical—users install the appropriate guide assembly prior to test setup; no recalibration is required between angles.
Is the system compatible with ASTM D903 and ISO 8510-2?
Yes—the mechanical design, force resolution, speed accuracy, and specimen geometry constraints fully satisfy the apparatus requirements specified in both standards.
Can test data be exported for third-party statistical analysis?
Yes—raw force-time data and summary statistics export natively to CSV, Excel-compatible XML, and PDF report formats.
Does the 80-91 require annual third-party calibration?
While not mandatory, TMI recommends annual verification using NIST-traceable weights and speed calibrators; internal calibration routines maintain traceability to ISO 9000-certified processes.
Is the touchscreen interface programmable without a connected PC?
Yes—the embedded controller supports standalone test definition, execution, and basic statistical review; PC connectivity is required only for advanced reporting, audit trail, and LIMS integration.
