Hanatek CFA Paperboard Crease and Folding Analyzer

Overview

The Hanatek CFA Paperboard Crease and Folding Analyzer is an engineered precision instrument designed specifically for quantitative mechanical characterization of pre-formed paperboard packaging—particularly folding cartons. It operates on the principle of controlled angular displacement under dynamic torsional loading, measuring real-time force response during crease bending and rebound. Unlike generic tensile testers, the CFA isolates and quantifies two interdependent yet distinct mechanical parameters critical to high-speed packaging line performance: (1) crease opening force—the energy required to initiate and sustain unfolding of a glued carton flap—and (2) board bending stiffness and elastic recovery behavior—including bending rebound moment, flexural modulus, and post-bend relaxation kinetics. These metrics directly correlate with feed reliability, jam frequency, and throughput stability on automated filling lines. The CFA is recognized as the first commercially available system capable of decoupling and independently measuring crease-specific energy thresholds in accordance with internationally harmonized test methodologies.

Key Features

• High-resolution angular actuation with <0.1° positional accuracy and programmable rotation speeds from 0.1°/s to 360°/s—enabling both quasi-static compliance testing and dynamic simulation of high-speed packaging motion profiles.
• Dual-mode force measurement: integrated mN-range load cell (±1 mN resolution, ±10 mN accuracy) for precise quantification of crease opening force and bending moment across variable angles up to 175°.
• Pre-configured, standards-compliant test protocols aligned with ISO 2493, ISO 5628, TAPPI T 556 om-05, TAPPI T 543 om-00, SCAN-P-29-95, DIN 53121, and BS 6965-1—ensuring method traceability and inter-laboratory comparability.
• Real-time force-angle curve acquisition and visualization: captures full mechanical hysteresis loops, including initial resistance, elastic rebound peak, fiber yielding onset, and post-yield relaxation—generating unique “mechanical fingerprint” signatures per sample.
• Flexible sample handling: accommodates variable specimen lengths (adjustable via calibrated scale), enabling evaluation of localized crease zones without requiring full-carton geometry.
• Integrated Windows XP-based touchscreen PC with Ethernet and IEEE 802.11 b/g/n connectivity—supporting networked data backup, remote diagnostics, and secure CSV export to USB storage media.

Sample Compatibility & Compliance

The CFA accepts standard cut specimens of corrugated board, solid bleached sulfate (SBS), coated recycled board (CRB), and laminated substrates used in pharmaceutical, food, and consumer goods packaging. Specimen width is standardized per ISO/BS protocols (typically 15–25 mm), while length is user-defined to isolate individual creases or evaluate multi-crease panels. All measurements comply with Good Laboratory Practice (GLP) documentation requirements, and raw data files retain full audit trails—including timestamp, operator ID, calibration status, and environmental metadata (if externally logged). The system supports FDA 21 CFR Part 11-compliant data integrity workflows when deployed with validated electronic signature modules and networked file management systems.

Software & Data Management

The embedded software provides intuitive test setup, real-time graphical overlay of multiple curves, and batch processing for comparative analysis across material grades, supplier lots, or manufacturing shifts. Each test generates a timestamped .csv file containing angle (°), torque (mN·mm), force (mN), time (s), and derived values (e.g., rebound ratio %, flexural modulus MPa, energy integral mJ). Exported datasets are fully compatible with statistical process control (SPC) platforms and LIMS integration. The system supports user-defined pass/fail thresholds based on historical benchmarks or internal specification limits, triggering alerts for out-of-tolerance crease behavior prior to production release.

Applications

• Optimizing crease geometry (depth, width, scoring angle) for improved fold consistency and reduced line stoppages.
• Validating adhesive cure profiles by correlating opening force with glue chemistry and dwell time.
• Assessing moisture-induced stiffness loss in humidity-controlled storage environments.
• Supporting root-cause analysis of carton collapse or misfolding in high-speed vertical form-fill-seal (VFFS) operations.
• Enabling predictive modeling of carton runnability using empirical correlations between CFA-derived energy metrics and actual line speed (e.g., mJ/crease vs. cycles/min).
• Facilitating supplier qualification through objective, repeatable benchmarking against ASTM/ISO reference materials.

FAQ

What standards does the CFA support for bending stiffness and crease rebound testing?
The CFA implements full compliance with ISO 2493:1992, ISO 5628:1990, TAPPI T 556 om-05, TAPPI T 543 om-00, SCAN-P-29-95, DIN 53121, and BS 6965-1:1988.
Can the CFA measure both single-crease and multi-crease panels?
Yes—specimen length is freely adjustable; users may isolate individual creases or evaluate sequential folds within one test sequence.
Is the system suitable for R&D environments requiring non-standard test speeds?
Absolutely—the angular velocity is continuously programmable from 0.1°/s to 360°/s, supporting both slow creep analysis and high-rate dynamic response studies.
How is data integrity ensured for regulated industries?
Raw data exports include full metadata, and the platform supports integration with validated electronic record systems compliant with 21 CFR Part 11 and EU Annex 11 requirements.
What maintenance is required for long-term measurement stability?
Annual recalibration of the load cell and angular encoder is recommended; all calibration constants are stored digitally and applied automatically during test execution.
