DIN 53369

시험 자료

DIN 53369 specifies the testing of heat-shrinkable films, often used in packaging and similar applications. Samples are typically cut to standardized dimensions (e.g., 130 mm × 15 mm) to ensure uniformity during testing​.

테스트 프로세스

The sample is heated to a predefined temperature (up to 210°C) to simulate heat shrinkage conditions. During the process, the system measures key parameters such as shrinkage force, contracting force, and shrinkage ratio. Once heated, the sample is cooled, and the system records the changes in real-time for analysis​.

테스트 결과 해석

Results are expressed in terms of shrinkage force, contracting force, and shrinkage ratio. These values indicate the material’s response to heat, crucial for assessing its performance in applications like packaging. Higher precision measurements enhance the reliability of the data​.
