Flex Durability Tester
The Flex Durability Tester is suitable for testing the rub resistance of various flexible films, composite films, and coated films. It is also known as a rub tester or film rub tester. It can simulate the rubbing, folding, and pressure damage that films experience during production, processing, and transportation. After the rub test, the material's rub resistance is evaluated by detecting changes in the number of pinholes or the barrier properties before and after the test, providing quantitative data for packaging design and practical applications.
Applications
- Packaging Industry: The rubbing resistance tester is widely used in the packaging industry. It helps enterprises detect the anti - rubbing ability of packaging materials, ensuring that products will not be damaged by external rubbing during transportation and storage. For example, food packaging and pharmaceutical packaging have extremely high requirements for rubbing resistance. Only through strict testing can the integrity of the packaging be guaranteed, thus safeguarding the quality and safety of the products.
- Material R & D: In the field of material research and development, the rubbing resistance tester is an indispensable tool. Experimenters can use it to study the performance characteristics of different materials, optimize material formulations and processes, and develop more durable and reliable new materials.
- Optimized Design: The test results of the rubbing resistance tester can provide quantitative data for packaging designers, helping them understand the performance of materials under specific conditions, thereby optimizing packaging designs. For example, designers can adjust the thickness, structure, or coating of packaging materials according to the test results to improve the durability and reliability of the packaging.
- Quality Control: Manufacturers can use the rubbing resistance tester to ensure that the quality of packaging materials meets relevant standards and regulatory requirements, thereby enhancing the market competitiveness of products and reducing safety risks caused by packaging problems.

In material R&D, it helps study performance characteristics, optimize material formulations, and develop more durable materials. For designers, test results provide quantitative data to improve packaging reliability and durability.
3. How does the tester simulate real-life rubbing conditions?
The Flex Durability Tester simulates real-life conditions by adjusting rubbing frequency and the number of rubbing times. Typical frequencies may include 45 times per minute, and multiple modes allow testing up to 2700 cycles. The specimen size is selected to reflect the material’s performance accurately, while force sensors monitor the state of the sample in real time. This ensures that the test results closely replicate the wear and stress experienced during actual handling and transportation.
4. What safety and operational features does the instrument include?
The tester is equipped with emergency stop buttons, overload protection, and program limit protection to ensure operator safety. A 7-inch touchscreen and PLC control system allow easy parameter setting and automated operation. Servo motors and precision ball screws provide accurate stroke positioning and low-noise operation. Optional accessories like pinhole detection and barrier testing devices enhance monitoring capabilities, allowing for comprehensive evaluation of material durability.
