Yuelian YL-S90 Pre-Coated Film Peel Strength Tester

Overview

The Yuelian YL-S90 Pre-Coated Film Peel Strength Tester is a precision-engineered electronic tensile testing machine designed specifically for quantitative mechanical evaluation of interfacial adhesion in coated and laminated film systems. It operates on the fundamental principle of controlled uniaxial force application—measuring peel resistance through standardized 90° or 180° peel configurations per ASTM D903, ISO 8510-2, and GB/T 2790–1995. Unlike general-purpose tensile testers, the YL-S90 integrates calibrated force transduction, high-resolution displacement tracking, and programmable speed control to ensure repeatability in low-force peel regimes typical of pre-coated release liners, pressure-sensitive adhesives (PSAs), label facestocks, and functional barrier films. Its architecture supports both standalone operation and synchronized data acquisition via dedicated software, enabling traceable, audit-ready test records compliant with GLP and internal QA workflows.

Key Features

• High-fidelity force measurement system with ±0.30% FS accuracy and 1/500,000 mm displacement resolution—optimized for sub-newton peel onset detection and plateau force stability assessment.
• Stepper motor-driven transmission with precision ground ball screw ensures consistent speed delivery across the full 0.5–600 mm/min range, minimizing inertial artifacts during rapid peel initiation.
• Dual-mode operation: fully autonomous single-key testing with real-time digital display, or PC-integrated mode supporting multi-parameter logging, curve overlay, and statistical batch analysis.
• Modular fixture interface with quick-release couplings accommodates ASTM-standard peel grips, floating rollers, and custom substrate holders for rigid, flexible, or composite substrates.
• Comprehensive safety logic including overload cutoff, specimen rupture auto-stop, upper/lower limit position triggers, and emergency stop—fully documented in system event logs.
• Standard RS-232 and USB interfaces enable direct connection to laboratory PCs or industrial printers; optional software supports CSV export, PDF report generation, and pass/fail threshold validation.

Sample Compatibility & Compliance

The YL-S90 is validated for testing thin-film assemblies with nominal thicknesses from 12 µm to 500 µm, including PET, BOPP, PE, and metallized substrates coated with silicone release layers, acrylic PSAs, or UV-curable adhesives. It meets mechanical requirements for ISO 11339 (adhesive tape peel testing), ASTM D3330 (pressure-sensitive tape adhesion), and GB/T 2792–2014 (peel strength of adhesive tapes). Force calibration is traceable to national metrology institutes via third-party certificate (available upon request). The system supports GMP-aligned documentation practices—including user-access-level controls, electronic signature capability, and 21 CFR Part 11–compliant audit trails when deployed with validated software modules.

Software & Data Management

The included PC software provides ISO/IEC 17025–aligned data handling: real-time force-displacement curve visualization, automatic peak/average/minimum peel force extraction, and configurable test protocols (e.g., dwell time before peel, ramp-to-load preconditioning). All raw data are stored in encrypted binary format with embedded metadata (operator ID, timestamp, environmental conditions, calibration status). Export functions support ANSI-standard CSV, Excel-compatible XLSX, and printable PDF reports with embedded calibration certificates and statistical summaries (n ≥ 5, mean ± SD, CV%). Audit logs record every parameter change, test execution, and firmware update—retained for minimum 12 months unless archived externally.

Applications

• Quantification of silicone release liner peel forces in medical device packaging and pharmaceutical blister lidding.
• Evaluation of adhesive anchorage integrity in flexible electronics encapsulation films and OLED barrier stacks.
• Quality control of pre-coated graphic arts films used in digital printing and automotive wrap applications.
• Development-stage screening of bio-based polymer laminates for sustainable packaging compliance (e.g., EN 13432).
• Validation of thermal or UV post-cure effects on PSA cohesion–adhesion balance in roll-to-roll manufacturing environments.

FAQ

What peel angles does the YL-S90 support?
The instrument is configured for standardized 90° and 180° peel tests per ISO 8510-2; angular fixtures are interchangeable and supplied as optional accessories.
Can it measure initial tack or loop tack?
No—the YL-S90 is optimized for steady-state peel resistance, not instantaneous tack. Loop tack requires specialized probe geometry and dynamic impact loading not supported by this platform.
Is calibration certification included?
A factory calibration report is provided; NIST-traceable recalibration services are available annually through authorized Yuelian service centers.
Does the system meet FDA or EU MDR requirements?
Hardware complies with IEC 61010-1 safety standards; full regulatory compliance depends on site-specific software validation, which the platform architecture supports via configurable audit trail and electronic signature modules.
What maintenance is required?
Routine checks include ball screw lubrication every 6 months, load cell zero verification before each shift, and periodic verification of encoder linearity using certified gauge blocks.
