Yuelian YL-S90 Film Puncture Tester

Overview

The Yuelian YL-S90 Film Puncture Tester is a precision-engineered electronic tensile testing system designed specifically for quantitative mechanical evaluation of puncture resistance in thin polymeric films, laminates, pharmaceutical packaging components, and biomedical barrier materials. Operating on the principle of controlled axial force application via a vertically actuated indenter probe (typically a stainless-steel needle or blunt-tip stylus), the instrument measures the peak force required to penetrate a clamped specimen under standardized displacement conditions. This test method aligns with core biomechanical and packaging integrity protocols—particularly those referenced in ASTM F2475 (Standard Test Method for Puncture Resistance of Packaging Materials), ISO 8503-2 (Surface Roughness Assessment for Coating Adhesion), and USP (Package Integrity Evaluation for Sterile Products). The system’s modular architecture supports interchangeable fixtures and programmable test profiles, enabling consistent execution of puncture, tensile, peel, and shear tests across regulated and R&D environments.

Key Features

• Multi-function mechanical testing platform supporting puncture, tensile, peel, shear, and compression modes within a single frame;
• High-resolution force transduction (1/500,000 full scale) and displacement measurement (1/500,000 stroke resolution), ensuring traceable repeatability in low-force regimes typical of thin-film applications;
• Stepper motor-driven crosshead with precision ground ball screw transmission, delivering stable speed control from 5 to 500 mm/min and minimizing mechanical hysteresis;
• Dual-limit protection system with overload shutdown, emergency stop, specimen failure auto-stop, and user-defined upper/lower stroke boundaries;
• Quick-release fixture interface compatible with standardized puncture probes (e.g., 1.0 mm diameter blunt tip per ASTM F2475), tensile grips, peel blocks, and custom tooling;
• Integrated micro-adjustment controls for precise specimen alignment and zero-position calibration prior to test initiation;
• Automatic return-to-home function post-test, reducing operator intervention and improving throughput in high-volume QA/QC labs.

Sample Compatibility & Compliance

The YL-S90 accommodates specimens up to 55 mm wide and 500 mm stroke depth, making it suitable for standard film strips (e.g., 100 × 100 mm), pharmaceutical stoppers, blister lidding foils, pouch seals, synthetic skin analogs, and multi-layer barrier laminates. Its force range (10 N – 1 kN) covers both delicate medical-grade films (500 N). The system supports compliance documentation workflows required under ISO/IEC 17025-accredited laboratories and GMP-regulated facilities. All force and displacement data are timestamped and stored with audit-trail metadata, facilitating adherence to FDA 21 CFR Part 11 requirements when paired with validated software configurations and electronic signature modules.

Software & Data Management

The proprietary PC-based control and analysis suite provides real-time dual-channel display of load vs. displacement, automatic curve annotation (yield point, peak puncture force, post-yield deformation), and export-ready reporting in PDF, CSV, and XML formats. Advanced functions include multi-curve overlay comparison, statistical batch analysis (mean, SD, CV%), modulus calculation (via linear regression of initial slope), and customizable pass/fail thresholds based on user-defined specification limits. The software employs MS-ACCESS relational database architecture for long-term data integrity, supports multi-sensor synchronization (e.g., optional environmental chamber integration), and features graphical configuration wizards for ASTM/ISO-compliant test templates. Data security protocols include role-based access control, electronic signature logging, and tamper-evident file hashing.

Applications

• Pharmaceutical packaging validation: puncture resistance of rubber stoppers, aluminum-plastic composite lids, and child-resistant closures;
• Medical device barrier assessment: burst strength and needle penetration force of surgical drapes, IV bag films, and wound dressing membranes;
• Food & beverage packaging QA: seal integrity testing of vacuum-sealed pouches, thermoformed trays, and retortable laminates;
• Biomedical material research: mechanical characterization of hydrogel films, electrospun nanofibers, and tissue-engineered scaffolds;
• Regulatory submission support: generation of GLP-compliant test reports for ANDA, NDA, and CE Marking dossiers;
• Process optimization: correlation of extrusion parameters, coating thickness, or annealing conditions with puncture performance metrics.

FAQ

What standards does the YL-S90 support for puncture testing?
The system is configured to execute ASTM F2475, ISO 8503-2, and USP test protocols out-of-the-box, with preloaded parameter sets and report templates.
Can the YL-S90 perform simultaneous multi-point puncture testing?
No—it is a single-axis, single-probe system; however, sequential puncture at multiple locations is supported via programmable XY-stage integration (optional accessory).
Is the software compliant with FDA 21 CFR Part 11?
Yes, when deployed with validated installation, electronic signature configuration, and audit-trail enabled—full validation documentation package available upon request.
What maintenance is required for long-term accuracy?
Annual force sensor calibration using NIST-traceable deadweight standards and periodic ball screw lubrication per manufacturer guidelines are recommended.
Does the system support automated data transfer to LIMS?
Yes, via configurable ODBC connectivity and structured CSV/XML export, enabling direct ingestion into common laboratory information management systems.
