Applications
This advanced Pendulum Impact Tester is specifically tailored for evaluating the impact resistance of various materials, including plastic film, composite film, metallic foil, and more. With applications ranging from scientific research and academic education to laboratory use, research institutes, and quality control departments, Pendulum Impact Tester is a versatile solution for precise and reliable testing.
Film:It is suitable for testing the resistance of plastic film, thin film and composite film to pendulum impact. Such as food and drug packaging bags with PE/PP composite film, aluminum plating film, aluminum plastic composite film, nylon film, etc
Paper, Sheet Testing:It is suitable for testing the impact resistance of paper and paperboard, such as aluminized paper for cigarette packaging and aluminum-plastic paper composite material for Tetra Pak packaging.

Test Procedures
1. Environmental Condition Control
Samples must be pretreated for at least 4 hours in an environment with a temperature of 23±2℃ and humidity of 45%～55% to avoid the influence of temperature and humidity on material properties (refer to GB/T 8809 and ISO standards).
2. Sample Preparation and Installation
Samples should be uniformly 100mm×100mm in size, with no wrinkles, bubbles, or damage on the surface.
Select the punch size according to the material characteristics (e.g., Φ12.7mm for thin films, Φ25.4mm for thick composite films) and match the corresponding fixture.
3. Equipment Parameter Calibration
Before testing, the initial angle of the pendulum (90°), impact velocity (2.5m/s), and energy zero point must be calibrated to ensure compliance with standards such as ASTM D3420.
Verify the equipment accuracy using standard samples to avoid errors caused by mechanical wear or sensor drift.
4. Data Acquisition and Analysis
Record the energy consumed by the punch during the impact process and analyze the material deformation characteristics in conjunction with the stress-strain curve.
Compare the material to standard thresholds (e.g., the impact resistance of food packaging composite films should be ≥2J) to assess whether the material meets the application requirements.
