GB/T 34848-2017 in English

This standard outlines the procedures for determining the shrinkage properties of heat shrinkable films. It provides detailed guidelines on the testing methods, including the equipment required, sample preparation, and the conditions under which the tests should be conducted. The standard ensures consistency in the measurement of how these films contract when exposed to heat, which is essential for quality control and product performance evaluation. The methodology described is designed to produce reliable and reproducible results, facilitating comparisons between different materials and manufacturing processes. The standard also specifies the conditions for storage and handling of samples to maintain their integrity throughout the testing process.
