Peel Strength Tester for Adhesive Tape & Release Film

Overview
The LabStone Peel Strength Tester is a dedicated laboratory instrument engineered for measuring the peel adhesion and release force of pressure‑sensitive materials. It is specifically designed for adhesive tapes, protective films, release liners, and label stocks—where even a 0.001 N difference can determine product quality and customer satisfaction.
This instrument is widely used by adhesive manufacturers, packaging converters, electronics assembly facilities, and third‑party testing laboratories for incoming QC, R&D validation, and regulatory compliance.

Key Functions
180° Peel Strength Testing - quantify adhesion of tapes, labels, and laminates
90° and T‑Peel Testing - evaluate protective film bonds and flexible laminate structures
Release Force Measurement - test release paper, release film, and silicone liners
Loop Tack / Initial Adhesion - available with optional fixtures
Suitable for R&D formulation, production QC, and compliance reporting

Working Principle
A specimen of tape, film, or release material is mounted in precision grips. The crosshead moves at a constant programmed speed (0–100 mm/min), creating a steady peeling or release action. A high‑sensitivity load cell captures the real‑time peel or release force. The embedded microprocessor simultaneously records the maximum peak value and average force, then automatically calculates statistical results across multiple specimens.

Frequently Asked Questions (FAQ)
Q1: What is the difference between peel strength and release force?
A: Peel strength measures the force required to separate an adhesive bond (e.g., tape from a surface) and is typically higher. Release force measures the resistance of a protective liner or release paper being peeled away from an adhesive—it should be consistently low and controlled. This instrument measures both with 0.001 N precision.
Q2: Can this tester handle very low‑tack adhesives?
A: Absolutely. With a 0.001 N resolution and speeds as low as 1 mm/min, it accurately measures even the slightest adhesion of low‑tack protective films and removable labels.
Q3: Which standards does this comply with?
A: The tester fully supports GB 4850, GB/T 2792, GB/T 2790, GB/T 2791, and related standards—all of which are currently valid and accepted for CNAS/CMA testing and customer audits.
Q4: What is the benefit of a ball screw vs. a belt drive?
A: A precision ball screw provides smoother motion, higher positional accuracy, and quieter operation compared to belt drives. This is critical for peel testing where consistent, vibration‑free movement directly impacts data quality—especially at low speeds.
Q5: Do I need the PC software, or can I use the machine standalone?
A: The machine operates independently with the host controller and built‑in printer for routine QC. The PC software is recommended for R&D work—it provides detailed curve analysis, database storage, statistical comparison, and professional report generation.
Q6: Can this test 90° or T‑peel configurations?
A: Yes. The standard machine supports 180° peel natively. With optional fixtures, it can be configured for 90° peel, T‑peel, and loop tack testing to meet diverse application needs.
Q7: What specimen width should I use?
A: Standard adhesive peel tests typically use 25 mm (1‑inch) wide specimens per GB/T 2792. The machine accommodates various widths—simply select the appropriate grip jaws for your specimen size.
