ZK Electronics BLD-200H Electronic Peel Strength Tester

Overview

The ZK Electronics BLD-200H Electronic Peel Strength Tester is a precision-engineered force measurement system designed specifically for quantitative evaluation of interfacial adhesion performance in flexible packaging and functional laminates. It operates on the fundamental principle of tensile force transduction during controlled 90° or 180° peel separation—measuring the resistive force required to progressively delaminate two bonded substrates at a defined angle and constant speed. This instrument adheres to standardized mechanical testing protocols widely adopted across global packaging R&D, QC laboratories, and regulatory compliance units. Its architecture integrates high-fidelity load cell technology with real-time kinematic control, enabling reproducible quantification of peel initiation force, steady-state peel resistance, and failure mode analysis—including cohesive, adhesive, or interfacial failure signatures.

Key Features

• Industrial-grade 7-inch high-resolution color touchscreen with intuitive menu-driven interface and responsive capacitive touch operation.
• Dual-mode test firmware supporting both peel strength (per ASTM D903, ISO 8510-2, GB/T 2792) and tensile strength (per ISO 527-3, GB/T 1040.3) protocols within a single platform.
• Real-time force–displacement curve visualization during test execution, with automatic annotation of peak load, plateau region, and total energy absorption.
• Statistical reporting engine delivering per-test maximum, minimum, and arithmetic mean values; group-level analysis includes standard deviation, coefficient of variation (CV%), and confidence interval estimation.
• Programmable termination criteria based on user-defined thresholds—including force magnitude, displacement distance, or time duration—to accommodate diverse material failure behaviors.
• Modular load cell configuration: interchangeable sensors rated at 5 N, 10 N, 30 N, 50 N, 100 N, or 200 N—each certified to better than Class 0.5 accuracy (IEC 61000-4-30 compliant) with resolution down to 0.001 N.
• Comprehensive safety architecture featuring hardware-based overload protection, mechanical end-stop limit switches, automatic zero-reset prior to each test cycle, and contextual fault diagnostics displayed directly on the HMI.
• Integrated thermal micro-printer for immediate hard-copy output of test ID, parameters, raw data snapshot, and statistical summary—fully traceable with timestamp and operator ID fields.

Sample Compatibility & Compliance

The BLD-200H is validated for testing a broad spectrum of pressure-sensitive and thermally activated adhesive systems used in packaging and medical device manufacturing. Compatible specimen types include pressure-sensitive tapes, release liners, protective films, battery electrode laminates, medical transdermal patches, and multilayer barrier films. All test methods align with national and international standards referenced in its design specification—including GB/T 2792 (equivalent to ASTM D3330), GB/T 2790 (adhesive shear strength), GB/T 2791 (adhesive peel strength on flexible substrates), and QB/T 2358 (plastic film peel resistance). The system supports GLP-compliant workflows through audit-trail-enabled data logging, user-access levels, and electronic signature readiness—meeting foundational requirements for FDA 21 CFR Part 11–aligned documentation practices when paired with optional PC-based software.

Software & Data Management

While the embedded firmware provides full standalone functionality, optional Windows-compatible software extends analytical capability with advanced curve fitting (e.g., exponential decay modeling of post-peak force relaxation), batch report generation (PDF/Excel), and database archiving with SQL-backed indexing. All stored records include metadata such as environmental conditions (optional external sensor integration), calibration history, operator credentials, and instrument firmware version. Data export supports CSV, XML, and ASTM E1447–compliant formats for LIMS interoperability. Audit trail logs capture every parameter modification, test initiation, result export, and user login event—retained for ≥36 months unless manually purged under documented SOP.

Applications

• Quality control of hot-melt and acrylic PSA formulations during roll-to-roll coating validation.
• Adhesion stability assessment of lithium-ion battery cathode/anode laminates after thermal cycling or humidity exposure.
• Comparative evaluation of silicone release coatings on PET liners versus competitive alternatives.
• Regulatory submission support for medical adhesive products requiring ISO 10993-5 cytotoxicity correlation with peel force thresholds.
• Process optimization of laminating line tension settings via correlation between peel strength and web speed.
• R&D screening of novel biodegradable film structures where interlayer delamination onset indicates formulation instability.

FAQ

What peel angles does the BLD-200H support?
The standard configuration supports 90° and 180° peel geometries using dedicated fixtures; custom angular fixtures (e.g., 45°) are available upon request.
Is calibration certification included with shipment?
Yes—each unit ships with a factory-issued calibration certificate traceable to CNAS-accredited reference standards, valid for 12 months under normal operating conditions.
Can the instrument interface with a laboratory information management system (LIMS)?
Via optional software module with configurable API endpoints and HL7/ASTM E1384 message mapping for seamless bidirectional data exchange.
Does the system meet requirements for ISO/IEC 17025 accredited testing laboratories?
When operated under documented procedures—including daily verification runs, scheduled recalibration, and environmental monitoring—the BLD-200H satisfies clause 6.4 (Equipment) and 6.5 (Measurement Traceability) of ISO/IEC 17025:2017.
Are replacement load cells field-swappable without tools?
Yes—modular sensor cartridges feature quick-release bayonet mounts and auto-recognized digital IDs; no manual scaling or zero adjustment is required post-installation.
