Pendulum Method Propagation Tear Resistance Tester Film And Thin Sheeting Tearing Force Tester Mn And Gf

Film And Thin Sheeting Tearing Force Tester

High-Precision Instrument for Measuring Tear Resistance in Flexible Materials

The Film And Thin Sheeting Tearing Force Tester is a laboratory-grade testing instrument engineered for accurately determining the tear resistance of flexible films and thin sheet materials. This high-performance tester utilizes the pendulum method to assess tear propagation resistance in materials such as plastic films, paper, textiles, waterproof composites, and other packaging substrates. It is widely used in quality control, R&D, and compliance testing across industries including packaging, food, medicine, beverages, academic research, and material production.

By measuring the energy loss as a pendulum tears through a precut slit in a specimen, the Film And Thin Sheeting Tearing Force Tester provides precise, repeatable, and standards-compliant tear resistance data. This ensures consistent product quality and meets regulatory and customer-specific requirements.

Key Applications

The Film And Thin Sheeting Tearing Force Tester is ideal for testing a variety of thin and flexible materials, including but not limited to:

• Plastic films (LDPE, HDPE, PET, PP)

• Thin sheeting and membranes (PVC, PVDC)

• Laminated packaging films

• Nonwoven and woven fabrics

• Kraft paper, cardboard, coated papers

• Textile samples and medical drapes

• Waterproof and breathable composite sheets

Its versatility makes it an essential instrument for manufacturers and laboratories focused on material strength, durability, and compliance.

Working Principle

This instrument operates on the pendulum tear test method, also referred to as the Elmendorf tear test. A pendulum arm is lifted and released, tearing the specimen from a precisely precut slit. The energy lost during the tear correlates with the force required to propagate the tear, which is automatically calculated and displayed. This method ensures consistent tear resistance values and supports high-throughput testing.

Advanced Features

• PLC-Controlled System: Ensures stable, intelligent control of the testing process.

• User-Friendly Interface: Touchscreen human-machine interface (HMI) for easy operation.

• Pneumatic Clamping: Provides firm and uniform specimen fixation, reducing human error.

• Automatic Pendulum Release: Enhances testing consistency and operational safety.

• Flexible Pendulum Capacity: Multiple pendulum options (200 gf to 6400 gf) for various material strengths.

• Auto Data Processing: Automatic statistics, test result storage, and report generation.

• Built-in Microprinter: Instantly print results for documentation and compliance audits.

• RS232 Data Output Port: For easy connection to PCs and optional software for analysis and archiving.
