Overview of the QTens-I Film Tensile Tester
The QTens-I film tensile tester is built as a single-column, bench-mounted station that lets your technicians examine thin specimens without occupying excessive workspace. Operating through a movable crosshead fitted with a precise load sensor, the unit applies pull forces up to 300 N, with an available 500 N selection, alongside an elongation range reaching 1250 percent. Its motorized drive delivers variable pulling speeds between 1 and 500 mm/min, giving your facility dependable control during routine break evaluations.
Qualitest supplies this system with an integrated LCD panel, built-in displacement detection, and an onboard micro-printer. You can run mechanical evaluations completely on its own without tethering a personal computer, or connect via its data interface when your team wants automated online recording.
Compliance & Standards
The QTens-I meets recognized international testing protocols used across production plants and material inspection facilities worldwide. For flexible polymer films and thin sheeting, the equipment fulfills ASTM D882 tensile testing and ASTM D1938 tear propagation requirements. When you configure the setup as a paper tensile strength tester, it satisfies ASTM D828 along with the Japanese industrial standard JIS P8113.
Additional test routines supported by the hardware include ASTM D3330 for peel adhesion of pressure-sensitive tapes and ASTM F904 for bond strength of flexible composites. The machine's force measurement components also follow ASTM E4 calibration criteria. Beyond physical mechanical guidelines, the onboard operating software follows GMP appendix rules for computerized systems, providing structured user permissions, secure login tiers, and complete audit trail tracking to help regulated facilities keep accountable records.
Key Features
- Load Capacity and Level 1 Measurement Accuracy: The system measures tension up to 300 N (with a 500 N option) at an accuracy within ±0.1% of full scale. This fine precision allows your operators to detect subtle changes in resistance when pulling fragile web materials.
- Variable Travel Speeds (1 to 500 mm/min): Continuous speed regulation enables your crew to follow exact test rates required by distinct testing guidelines without mechanical gear adjustments.
- Bench-Friendly Single-Column Layout: Unlike heavier floor-standing tensile testing machines for plastics, this 76.5 kg, single-column frame sits comfortably on a standard laboratory workbench, allowing comfortable seated operation.
- Integrated Display and Dual Operating Modes: An onboard LCD presents live test curves and raw values directly to seated operators. Because data processing runs directly on the machine, you can run routines in standalone mode or connect to an external computer for online data capture.
- Micro-Printer Integration: A built-in thermal printer produces hard-copy test summaries right at the testing bench, minimizing manual recording mistakes.
- Multi-Tier Safety Safeguards: Mechanical limit switches, electronic overload detection, and a dedicated emergency stop switch protect your load cell and frame from accidental impacts during continuous shifts.
- High Data Acquisition Rate: Capturing readings at 100 points per second ensures that quick peak loads, yield points, and sudden rupture moments are captured faithfully.
- Configurable Gripping Distance: Offering 750 mm of vertical travel (customizable to 1000 mm) and standard 30 mm test widths (customizable to 50 mm), this hardware accommodates elongated specimens that stretch significantly before snapping.
Product Applications & Operating Environments
The QTens-I serves inside indoor quality control laboratories, packaging production floors, university research centers, and third-party inspection firms. It provides dependable tension, peel, heat-seal, and tear analysis across multiple everyday materials:
- Plastic Films and Flexible Barrier Sheets: Evaluates seam integrity, break limits, and tear resistance across flexible multilayer packaging and monolayer plastics.
- Composite Packaging Pouches: Measures lamination peel strength and heat-seal endurance on retort pouches, foil-laminate barriers, and co-extruded bags.
- Paper and Sanitary Sheet Products: Serves as an effective inspection tool to determine the tensile pull resistance of kraft packaging stock, facial tissues, and rolled bathroom papers.
- Adhesive Tapes and Pressure-Sensitive Adhesives: Verifies strip peel resistance and pull-off force for cellophane wraps, industrial insulating tape, and zinc oxide medical adhesives.
- Medical Compresses and Skin Patches: Tests adhesion, stretch properties, and peel resistance for cold compresses and medicated plasters.
Because this hardware is configured for standard indoor testing facilities, it operates best on stable laboratory benches with regular single-phase electrical supply (220 V AC at 50 Hz, or 110 V upon request).
