Labthink C611B Compression Tester for Corrugated Boxes and Packaging Containers

Overview

The Labthink C611B Compression Tester is a precision-engineered mechanical testing system designed specifically for evaluating the compressive performance of corrugated fiberboard containers, honeycomb packaging, and rigid hollow containers used in logistics and distribution environments. It operates on the principle of uniaxial compression under controlled displacement rate, measuring force response and axial deformation to quantify structural integrity, crush resistance, and stack-load endurance. The instrument conforms to internationally recognized static and dynamic compression test protocols—including top-load, constant-load, and time-dependent creep modes—making it suitable for quality assurance laboratories in packaging manufacturing, e-commerce fulfillment centers, pharmaceutical secondary packaging validation, and regulatory compliance departments requiring traceable mechanical data.

Key Features

• Integrated embedded computing platform with Windows-style GUI interface—no external PC required; operation via keyboard and optical mouse ensures intuitive workflow navigation.
• Dual high-precision ball-screw drive system coupled with a brushless servo motor enables smooth, repeatable load application across the full speed range (0–200 mm/min), programmable in integer increments for precise method alignment.
• Triple 9 kN load cells (redundant configuration) deliver high linearity and long-term stability, with force accuracy of ±1% FS (10–100% range) and ±0.1% FS (0–10% range), meeting ISO 7500-1 Class 1 requirements.
• Real-time synchronized display of compressive force (N/kN) and vertical deformation (mm) during test execution, supporting immediate visual assessment of load–displacement curves.
• Comprehensive safety architecture including over-load protection, end-of-travel limit switches, automatic fault detection, and audible/visual alarm triggers—designed for operator safety and equipment longevity.
• USB 2.0 and Ethernet (RJ45) interfaces enable seamless data export, remote diagnostics, and integration into LIMS or enterprise QA systems.

Sample Compatibility & Compliance

The C611B accommodates standard shipping containers up to 600 mm in height and footprint, including single- and double-wall corrugated boxes, edge-crushed test (ECT)-rated cartons, molded pulp trays, and rigid intermediate bulk containers (IBCs), plastic drums, fiber drums, and paper cans. Its platen geometry supports uniform load distribution without edge effects, critical for reproducible results per ASTM D642 (determining compressive strength of shipping containers) and ISO 12048 (compression testing of corrugated fiberboard boxes). Optional GMP-compliant software modules provide audit trails, electronic signatures, and 21 CFR Part 11–aligned data security features—including role-based access control and immutable record generation—to satisfy pharmaceutical and medical device packaging validation requirements.

Software & Data Management

The onboard software implements Labthink’s proprietary DataShield™ architecture, enabling centralized data governance, encrypted storage, and secure export to CSV, PDF, or XML formats. All test parameters, raw sensor outputs, timestamps, user IDs, and calibration logs are automatically archived with versioned metadata. For regulated environments, optional computer system validation packages support IQ/OQ documentation, electronic signature implementation, and GLP/GMP-aligned reporting workflows. Data synchronization across networked instruments allows cross-site comparative analysis and trending of material performance over time—essential for continuous improvement programs in packaging R&D and supplier qualification.

Applications

• Paperboard Container Evaluation: Crush resistance (top-load test), stacking simulation (constant-force hold), and creep deformation analysis under sustained load per ASTM D4169 Cycle 11 or ISTA 3A.
• Hollow Container Testing: Structural collapse threshold measurement for plastic pails, fiber-reinforced drums, and composite cans—supporting both pass/fail criteria and failure mode classification.
• Material Development Support: Comparative testing of new linerboard grades, adhesive formulations, flute geometries, and moisture-barrier laminations under standardized compression profiles.
• Regulatory Submission Preparation: Generation of auditable test reports compliant with FDA, EMA, and PMDA packaging guidance documents related to primary and secondary containment integrity.
• Supply Chain Qualification: Validation of packaging performance across temperature/humidity preconditioning cycles (e.g., after ASTM D4332 conditioning) prior to distribution simulation.

FAQ

What standards does the C611B comply with?
ASTM D642, ASTM D4169, ISO 12048, TAPPI T804, JIS Z0212, GB/T 16491, GB/T 4857.4, and QB/T 1048-2004.
Can the instrument perform both crush and stack-hold tests?
Yes—it supports three distinct test modes: crush (peak force at failure), stack A (deformation under increasing load), and stack B (deformation under constant load over time).
Is calibration traceability available?
Yes—each unit ships with NIST-traceable calibration certificates for force and displacement channels; annual recalibration services are supported globally.
Does the system meet FDA 21 CFR Part 11 requirements?
With the optional GMP software package, it provides electronic signatures, audit trails, and data integrity controls aligned with Part 11 and Annex 11 expectations.
What is the maximum sample height the tester can accommodate?
600 mm, with a total internal test space of 600 mm (L) × 600 mm (W) × 610 mm (H).
