Overview
The Labthink YGJ-02A Automatic Roller-Type Adhesion Tester is a precision-engineered instrument designed for standardized mechanical adhesion assessment of printed ink layers, vacuum metallized coatings, surface-applied functional films, and laminated structures on flexible packaging substrates. It operates on the principle of controlled roller compression followed by quantitative peel evaluation—aligning with internationally recognized pressure-sensitive adhesion test methodologies. The device applies a calibrated normal force via a high-stability rubber-coated steel roller, ensuring consistent contact geometry and interfacial stress distribution during lamination. This process simulates real-world handling conditions encountered in packaging conversion, printing finishing, and post-lamination processing. Unlike manual or semi-automated alternatives, the YGJ-02A integrates closed-loop speed regulation, programmable cycle control, and load stability verification—minimizing operator-induced variability and supporting GLP-compliant data traceability.
Key Features
- Microprocessor-controlled operation with intuitive PVC membrane keypad and backlit LCD display for real-time parameter monitoring and configuration.
- Dual preset rolling speeds (300 mm/min and 600 mm/min), plus fully adjustable non-standard speed range to accommodate method-specific requirements per ASTM D3330, ISO 8510-2, or internal SOPs.
- Precision-machined roller assembly featuring certified rubber sleeve (Shore A hardness and thickness per GB/T 7707-2008 Annex B), mounted on rigid stainless-steel shaft with dynamic load compensation.
- Fixed 20 N ± 0.2 N applied load, verified traceably against national metrological standards; load uniformity maintained across full roller width (25 mm).
- Programmable rolling cycles (1–999), enabling repeatable multi-pass lamination for evaluating cumulative interface conditioning effects.
- Integrated acoustic alarm signaling completion of rolling sequence, enhancing laboratory safety and procedural discipline.
- Compact benchtop footprint (360 × 230 × 260 mm) optimized for integration into QC labs, R&D workstations, and ISO 17025-accredited testing environments.
Sample Compatibility & Compliance
The YGJ-02A supports standard specimen widths up to 150 mm and accommodates substrates including BOPP, PET, CPP, PE, aluminum foil composites, metallized PET, and glassine paper—provided they meet minimum tensile stiffness and surface energy criteria for reliable roller engagement. It complies with mandatory test protocols referenced in GB/T 7706 (letterpress decorative prints), GB/T 7707-2008 (gravure decorative prints), GB/T 4851 (pressure-sensitive tape holding power), and GB/T 2792-2014 (peel strength of pressure-sensitive tapes). International equivalency includes JIS Z0237 (Japanese industrial standard for PSAs) and JIS C2107 (electrical-grade tape testing). All mechanical tolerances—including roller diameter, rubber durometer, and load deviation—are validated per CNAS-CL01:2018 requirements for accredited calibration laboratories.
Software & Data Management
While the YGJ-02A operates as a standalone electromechanical tester without embedded PC connectivity, its operational parameters are fully documented in Labthink’s TestLog™ documentation package—a secure PDF-based record template aligned with FDA 21 CFR Part 11 principles for audit readiness. Each test run generates a timestamped log sheet capturing date/time, operator ID, sample ID, selected speed, applied load, cycle count, environmental RH/temperature (if logged externally), and pass/fail judgment per visual inspection criteria defined in GB/T 2792-2014 Section 6. Optional integration with Labthink’s optional DataBridge™ USB interface module enables direct export of test metadata to LIMS or ELN systems—supporting automated report generation and long-term trend analysis under ISO/IEC 17025 Clause 7.7.
Applications
- Quantitative evaluation of ink-to-film adhesion in gravure and flexographic printing lines prior to slitting or converting.
- Validation of metallization bond integrity in decorative packaging and barrier film production.
- Quality gate testing for release liner adherence in medical adhesive tape manufacturing.
- Comparative assessment of surface treatment efficacy (e.g., corona, plasma, flame) on polymer films.
- Process qualification of cold-seal coating applications in pharmaceutical blister packaging.
- Root cause analysis of delamination failures in multi-layer laminates subjected to thermal or humidity cycling.
FAQ
What standards does the YGJ-02A directly support?
It is engineered to execute test sequences compliant with GB/T 7707-2008, GB/T 2792-2014, GB/T 4851, JIS Z0237, and JIS C2107 without hardware modification.
Is calibration certification included with shipment?
Yes—each unit ships with a factory-issued calibration certificate traceable to CNAS-accredited primary standards, covering roller load accuracy and speed linearity.
Can the roller be replaced or reconditioned?
The rubber sleeve is a consumable component; Labthink supplies certified replacement sleeves with pre-verified hardness and dimensional conformity.
Does the instrument require external environmental control?
No—but test specimens must be conditioned per GB/T 2918 (23 °C ± 2 °C, 50 % RH ± 5 % RH) prior to rolling, per standard methodology.
Is technical support available outside mainland China?
Yes—Labthink provides remote diagnostics, application engineering consultation, and authorized service partner referrals across APAC, EMEA, and North America.
