Elmendorf Tear Tester – QualiELM™ Series

Fast, repeatable tear strength testing for paper, film, and textiles.

An Elmendorf Tear Tester measures the tear resistance (tear strength) of sheet materials using a pendulum-based method. It determines the force required to propagate a tear after a controlled pre-cut, making it a widely used, standardized approach for comparing material durability. Labs rely on Elmendorf tear testing to validate consistency across production batches, confirm material performance, and support product development with repeatable results.

The QualiELM™ Series Elmendorf Tear Tester is designed for routine quality control and R&D work where stable clamping, consistent cutting, and clear readings matter. It supports efficient testing workflows, helping teams reduce re-testing and improve confidence when qualifying incoming materials or releasing finished goods.

Applications of an Elmendorf Tear Tester

Elmendorf tear testing is commonly used when you need to evaluate how a material resists tearing during handling, converting, packaging, or end use.

• Paper and Paperboard: Compare tear strength between grades, coatings, or fiber blends for packaging and printing applications.
• Plastic Films and Flexible Packaging: Evaluate film toughness and tear propagation behavior for bags, pouches, and multilayer laminates.
• Textiles and Nonwovens: Assess tear resistance for protective fabrics, wipes, medical nonwovens, and industrial textiles.
• Tapes, Labels, and Adhesive Backings: Verify durability of backing materials that must resist tearing during application and removal.
• Quality Control and Supplier Qualification: Standardize acceptance criteria across suppliers and lots to reduce variability in incoming materials.
• Product Development and Material Selection: Compare candidate materials and optimize structures for strength-to-weight performance.
