ISO 7765 Plastic Film Impact Resistance Tester Dart drop impact tester

Advanced Solution for Evaluating Impact Strength of Plastic Films

The Plastic Film Impact Resistance Tester is a precision instrument engineered to evaluate the ability of plastic films to withstand external impact forces. Based on ISO 7765, this dart drop impact testing system plays a critical role in quality control and R&D across industries including packaging, pharmaceuticals, food, beverage, plastics, and material science.

By simulating the impact of a free-falling dart on film samples, the instrument determines the impact resistance—expressed as the weight/mass causing failure in 50% of the specimens tested. This reliable method provides key insights into film strength, uniformity, and material behavior under sudden force, making it an indispensable tool in any physical property testing laboratory.

• Educational and Research Institutions: For material science studies and lab training.

Whether you are a film manufacturer or a packaging material researcher, our Plastic Film Impact Resistance Tester delivers the consistent performance and data integrity required for your laboratory tests.

Testing Principle Explained

The test is conducted by dropping a hemispherical dart from a controlled height onto the center of a horizontally clamped film sample. The Plastic Film Impact Resistance Tester automatically determines whether the film fails or passes based on visual observation or predefined criteria. Multiple samples are tested to identify the weight that results in 50% failure, providing a quantified measurement of film impact resistance.

Both Method A and Method B are selectable:

• Method A: Uses a smaller dart (38 mm) and tests lighter, more flexible films.

• Method B: Uses a larger dart (50 mm) for thicker, stiffer materials.
