GBPI GBH-1T Universal Electronic Tensile Testing Machine with Puncture & Peel Force Measurement Capability

Overview

The GBPI GBH-1T is a single-column, electromechanical universal tensile testing machine engineered for high-precision mechanical characterization of flexible packaging materials and thin-sheet specimens. It operates on the principle of controlled uniaxial force application via a precision ball-screw-driven crosshead, coupled with real-time load and displacement transduction. Designed for compliance with international standard test methods—including ASTM D882 (tensile properties of thin plastic sheeting), ASTM F88 (seal strength of flexible barrier materials), ISO 37 (rubber—determination of tensile stress-strain properties), and multiple Chinese national standards (e.g., GB/T 1040, GB/T 8808, GB/T 2792)—the system delivers traceable, repeatable mechanical data across tension, peel, puncture, tear, compression, bending, and shear modes. Its modular architecture supports interchangeable fixtures and sensor configurations, enabling laboratory-grade quantification of mechanical integrity in films, laminates, foils, nonwovens, elastomers, and coated papers under controlled environmental and kinematic conditions.

Key Features

• Class 0.5 force accuracy (±0.5% of reading) certified per ISO 7500-1 and ASTM E4, validated across full dynamic range from 0.5% to 100% FS.
• High-resolution displacement measurement with ±0.5% linearity, supported by a low-drift, high-stiffness ball-screw actuation system ensuring long-term mechanical stability and minimal thermal drift.
• Programmable test speed from 0.01 to 500 mm/min, enabling both quasi-static and rapid deformation protocols required for regulatory-compliant seal strength (ASTM F88), peel adhesion (ASTM D3330), and puncture resistance (ASTM D3776) testing.
• Dual-mode control architecture: internal embedded controller for standalone operation or PC-integrated mode with full data acquisition, real-time curve overlay, and automated report generation.
• Modular fixture interface accommodating pneumatic clamps (optional), self-aligning grips, puncture probes (e.g., 1.0 mm diameter hemispherical tip per ASTM F1306), and peel angle fixtures (90°/180°) without tooling change.
• 100 Hz sampling rate ensures accurate capture of transient events such as seal failure initiation, film yielding, or adhesive debonding onset.
• Comprehensive safety subsystem including mechanical end-limit switches, electronic overload cutoff, emergency stop circuitry, and software-enforced operational boundaries compliant with IEC 61000-6-2 EMC and ISO 12100 functional safety principles.

Sample Compatibility & Compliance

The GBH-1T is optimized for specimens ≤1.0 mm thick and ≤50 mm wide, including but not limited to biaxially oriented polypropylene (BOPP), PET/Al/PE laminates, aluminum foil composites, medical-grade Tyvek®, hydrocolloid dressings, pressure-sensitive adhesives, and pharmaceutical blister lidding materials. It fully supports pharmacopoeial and regulatory test protocols: YBB00112003 (China Pharmacopoeia for packaging materials), USP (package integrity), and FDA 21 CFR Part 11–compliant audit trails when paired with validated software modules. All mechanical outputs—including peak load, elongation at break, modulus, seal strength (N/15 mm), and puncture energy (N·mm)—are directly exportable to CSV or Excel formats for GLP/GMP documentation and statistical process control (SPC) analysis.

Software & Data Management

The included GBPI TestMaster v3.x software provides ISO/IEC 17025-aligned data handling: automatic calibration certificate logging, user-access-level permissions (operator, supervisor, administrator), electronic signature support, and immutable audit trail generation meeting FDA 21 CFR Part 11 requirements. Raw force-displacement data streams are stored with timestamped metadata (test ID, operator, environmental conditions, fixture ID). Advanced analysis tools include multi-curve superposition, derivative-based yield point detection, area-under-curve (AUC) calculation for energy absorption, and customizable pass/fail thresholds against specification limits. Data structures are open XML-based, allowing direct integration with LIMS platforms or custom Python/R scripts for statistical modeling.

Applications

• Quantitative assessment of heat-seal strength in flexible food and pharmaceutical packaging per ASTM F88 and GB/T 2792.
• Puncture resistance evaluation of medical pouches and protective films using standardized probes per ASTM F1306 and ISO 11607-2.
• Peel adhesion testing of pressure-sensitive tapes and labels per ASTM D3330 and GB/T 7122.
• Tensile property mapping (modulus, ultimate tensile strength, % elongation) of polymer films per ASTM D882 and GB/T 1040.3.
• Delamination force measurement in multilayer laminates per ASTM D1876 (T-peel) and GB/T 2791.
• Educational use in materials science laboratories for hands-on instruction in mechanical behavior of polymers and composites.

FAQ

What standards does the GBH-1T comply with for pharmaceutical packaging testing?
It supports all major Chinese pharmacopoeial standards (YBB series), ASTM F88/F904 for seal integrity, and ISO 11607-2 for sterile barrier systems—with optional validation packages available for GMP environments.
Can the system perform simultaneous multi-channel measurements?
Yes: the load cell channel and displacement encoder operate independently at 100 Hz; optional auxiliary channels support extensometer or environmental sensor inputs (e.g., temperature-compensated strain measurement).
Is firmware and software update support provided post-purchase?
GBPI offers free minor version updates and paid annual maintenance contracts including calibration verification, remote diagnostics, and regulatory compliance advisory services.
What is the warranty coverage and service response time?
Standard 24-month parts-and-labor warranty; on-site technical support within 5 business days in Tier-1 cities across APAC and EU regions, subject to service agreement terms.
