Film Heat Shrinkage Tester
The film heat shrinkage rate tester is a device specifically designed to measure the shrinkage performance of film materials under heating conditions. The following is a detailed description of its main uses, compliance standards, and technical parameters:
Main Uses
The film heat shrinkage rate tester is mainly used to test the heat shrinkage performance and dimensional stability of various film materials, heat - shrinkable tubes, pharmaceutical PVC sheets, backplanes, etc. in liquid media at multiple temperatures. By precisely measuring the dimensional changes of the film before and after heating and calculating its heat shrinkage rate, the heat shrinkage performance of the material can be evaluated. This performance is directly related to the quality and reliability of products. In the packaging industry, such as in the fields of food, beverages, cosmetics, etc., film materials are widely used for product packaging. The quality of their heat shrinkage performance directly affects the packaging effect and product safety. Through the testing of the film heat shrinkage rate tester, problems that may occur during the heat shrinkage process of materials, such as uneven shrinkage and failure to meet the shrinkage rate standard, can be promptly identified and resolved, thus ensuring the quality of packaging materials.
Compliance Standards
GB/T 13519 and ASTM D2732. etc.
Technical Parameters
- Testing Range: Applicable to the heat shrinkage performance testing of various film materials, heat - shrinkable tubes, etc.
- Temperature Control Accuracy: Usually with high temperature control accuracy, such as ±0.3°C, to ensure the accuracy and stability of the testing temperature. - Heating Medium: Generally, the liquid medium heating method is adopted, such as oil bath. The selection of the heating medium should be determined according to the testing materials and testing conditions. - Specimen Size: The specimen size is usually limited, such as not larger than 140mm×140mm, etc. The specific size should be determined according to the testing standards and equipment requirements. - Testing Temperature: The testing temperature range is wide and can be adjusted according to actual needs. The testing temperatures for different materials and in different application scenarios may vary. - Testing Time: The testing time can be set according to actual needs. It usually includes parameters such as pre - heating time and testing time. The pre - heating time is used for the equipment to reach the preset temperature and remain stable; the testing time is used to observe and record the shrinkage of the specimen. - Data Recording and Analysis: Modern film heat shrinkage rate testers are usually equipped with data recording systems and analysis software, which can automatically record testing data and perform processing and analysis. This helps users more intuitively understand the heat shrinkage performance of materials and provides a basis for subsequent product design and quality control.
