Film Shrinkage test, known as linear thermal shrink test or free shrink test, is used for analyzing the effect of temperature on heatshrinkable films made from polyethylene, ethylene copolymers and their mixtures. Basically, shrinking force, contracting force and shrinking ratio can be measured in such determination.
The percent shrinkage is read directly from a scale or display on the instrument while the specimen is still under tension and exposed to heat. The standard ASTM D4974 testing method is to heat the sample.
The Global Thermal Shrinkage Tester market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Labthink C631H Thermal Shrinkage Tester – C631H Thermal Shrinkage Tester is designed and developed in accordance with ISO 14616 and GB/T 34848, for determination of shrinking force, contracting force and shrinkage ratio of heatshrinkable films. Shrinking force greater than 0.01N can be detected.
The specimen is placed in the test area for displacement and force measurement, it is then heat to the specified temperature for shrinkage test and cooled down. The system automatically records the shrinking force, temperature and shrinkage ratio in real time and provides analytical results.
RSY-R2 Shrink Tester – RSY-R2 Film Free Shrink Tester is professionally applicable to the determination of heat shrinking performance and dimensional stability of various films, heatshrinkable tubes, hard PVC films for tablets, and back-sheets in the fluid medium at different temperatures.
The instrument can be used to test the heat shrinking performance of various films in fluid medium at different temperatures, e.g. PE heatshrinkable films used for packages of liquor, mineral water and beverages as well as PVC, POF, OPS, and PET which are available for various packages.
Digital P.I.D. temperature control technology ensures the preset temperature to be reached rapidly without any fluctuation . The instrument is heated through fluid medium, which could provide the stable test environment . Automatic timer function to efficiently guarantee the accuracy of test data .
The instrument is controlled by micro-computer with LCD, PVC operation panel, and menu interface . Has a Standard clamp wire mesh support could make the test done smoothly.
