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.

FAQ

1. What is the main purpose of the Pendulum Impact Testing Machine for Plastic Film?

The Pendulum Impact Testing Machine is designed to evaluate the impact resistance of plastic films, thin films, and composite films. It can measure the energy absorbed during fracture, allowing precise assessment of material toughness. This is particularly important for food and drug packaging bags, aluminum-plastic composite films, and nylon films, ensuring that the materials meet the mechanical requirements for safe handling, transport, and usage.

2. What types of materials can be tested with this machine?

This tester is suitable for a wide range of materials, including plastic films, composite films, metallic foils, paper, and paperboard. Examples include PE/PP composite food packaging films, aluminum-plastic films, aluminum-plated films, cigarette packaging aluminized paper, and Tetra Pak composite materials. Its versatility allows research institutes, laboratories, and quality control departments to evaluate impact resistance in multiple applications.

3. How does the machine ensure accurate and repeatable results?

The machine uses high-precision electronic measurement with a resolution of up to 0.001 J and a constant impact velocity of 2.5 m/s. Pneumatic clamping and pendulum release systems reduce human error, while calibration with standard samples ensures that sensor drift or mechanical wear does not affect results. The microcomputer control system automatically collects data, provides statistical analysis, and displays visualized results, ensuring precise and repeatable testing outcomes.

4. How are samples prepared for testing?

Samples must be pretreated for at least 4 hours in an environment with 23±2℃ and 45%-55% humidity to stabilize material properties. They should be cut to uniform 100mm×100mm sizes without wrinkles, bubbles, or damage. The punch size is selected based on film thickness, and the appropriate fixture is chosen to ensure proper clamping. Proper preparation guarantees the accuracy and reliability of the measured impact resistance.

5. How is the energy absorbed by the material measured and analyzed?

During testing, the punch strikes the sample, and the energy consumed is recorded by the machine. This energy value reflects the material’s impact toughness and resistance to fracture. Data is analyzed alongside stress-strain curves to understand deformation characteristics. Materials are then compared to standard thresholds, such as requiring ≥2J for food packaging composite films, to determine if they meet application requirements and safety standards.
