Yuelian YL-S90 Aluminum-Laminated Film Puncture Tester

Overview

The Yuelian YL-S90 Aluminum-Laminated Film Puncture Tester is a microprocessor-controlled electronic tensile testing system engineered for high-reproducibility mechanical evaluation of thin flexible packaging materials—particularly aluminum-plastic laminates used in pharmaceutical blister packs, IV bags, pouches, and sterile barrier systems. It operates on the fundamental principle of controlled axial force application through a precision-driven puncture probe (typically ASTM F1306-compliant conical or flat-tipped stylus), measuring the peak puncture force (in Newtons) required to breach the film under standardized displacement conditions. The instrument complies with core regulatory test methodologies including ISO 11607-2 (Packaging for terminally sterilized medical devices), ASTM F2475 (Standard Test Method for Puncture Resistance of Flexible Barrier Materials), and USP (Package Integrity Evaluation – Sterile Products). Its rigid frame, low-inertia stepper motor actuation, and high-resolution load cell enable repeatable quantification of puncture resistance, seal integrity, and material toughness across R&D, QC, and stability testing environments.

Key Features

• Multi-function mechanical testing platform supporting puncture, tensile, peel, tear, compression, and bend tests per ISO 6892-1, ASTM D882, ASTM D3330, and ISO 11339 standards.
• High-precision load measurement with ≤ ±0.5% full-scale accuracy and 1/500,000 internal resolution—traceable to national metrological standards.
• Programmable crosshead speed from 5 to 500 mm/min, adjustable via PC interface; real-time synchronization of force and displacement data acquisition at ≥1 kHz sampling rate.
• Modular fixture interface with quick-release couplings—compatible with standard puncture probes (e.g., 1.0 mm radius conical tip), film grips, peel jigs, and custom tooling per customer specifications.
• Integrated auto-return and end-of-test stop logic—including overload cutoff, upper/lower limit position protection, specimen rupture detection, and emergency halt activation.
• Low-noise, maintenance-free stepper motor drive coupled with preloaded ball screw transmission ensures minimal backlash (<0.01 mm) and long-term positional stability over 10,000+ test cycles.

Sample Compatibility & Compliance

The YL-S90 accommodates specimens up to 55 mm wide and 500 mm travel distance, making it suitable for single-layer films (e.g., PET/AL/PE), co-extruded laminates, cold-formable aluminum foils, polymer-coated Tyvek®, synthetic skin analogs, rubber stoppers, and flip-off caps. All test configurations adhere to GLP-compliant documentation requirements: audit-trail-enabled software logs operator ID, timestamp, calibration status, environmental conditions (optional sensor integration), and raw force-displacement datasets. Data export supports CSV, PDF, and XML formats compatible with LIMS and FDA 21 CFR Part 11–compliant validation packages. System validation documentation (IQ/OQ/PQ protocols) and traceable calibration certificates are available upon request.

Software & Data Management

The embedded Windows-based control software provides full test sequence definition, real-time graphical monitoring, and post-test analysis without third-party dependencies. Key capabilities include automatic calculation of puncture peak force, energy-to-puncture (area under curve), yield point, modulus (via tangent or secant method), and elongation at break. Multi-curve overlay, statistical batch reporting (mean, SD, CV%, min/max), and pass/fail threshold enforcement support routine QC release testing. Database backend utilizes Microsoft Access for structured storage of test records with field-level encryption and user-role access control (admin, operator, reviewer). Software includes built-in safeguards: hardware interlock verification, firmware signature checks, and tamper-evident digital signatures for exported reports.

Applications

• Pharmaceutical packaging: Blister foil puncture resistance (ASTM F1306), vial stopper penetration force (USP ), and child-resistant closure evaluation.
• Medical device packaging: Seal strength validation of Tyvek®-poly laminate pouches per ISO 11607-2 Annex B.
• Food & beverage: Evaluation of retort pouch integrity, vacuum-sealed film toughness, and lid peel performance.
• Biomedical R&D: Quantification of synthetic epidermal membrane puncture thresholds for transdermal patch development.
• Quality assurance labs: Routine incoming inspection of aluminum-laminated roll stock, shelf-life degradation studies, and supplier qualification testing.

FAQ

What puncture probe geometries are supported?
Standard configurations include ASTM F1306-conforming conical probes (1.0 mm tip radius, 30° included angle) and flat-ended cylindrical probes (1.5 mm diameter); custom probes can be integrated upon specification submission.

Is the system compliant with FDA 21 CFR Part 11?
Yes—the software supports electronic signatures, audit trails, role-based permissions, and data integrity controls required for regulated GMP/GLP environments; full validation support documentation is provided.

Can the YL-S90 perform simultaneous multi-point puncture testing?
No—this is a single-axis, single-probe system designed for standardized uniaxial puncture per recognized methods; multi-point testing requires sequential positioning or optional motorized XY stage add-ons.

What calibration intervals are recommended?
Annual recalibration against certified reference loads is advised; internal verification using traceable check weights (supplied) should be performed before each shift or test series.

Is technical support available outside mainland China?
Yes—remote diagnostics, English-language documentation, firmware updates, and application engineering consultation are provided globally via authorized regional partners and direct Yuelian technical support channels.
