Good POF shrink film is made of new materials, and the shrinkage effect is better than that of recycled POF shrink film. How to detect the quality of POF shrink film, set test parameters such as test temperature and end temperature, click the start test option, and the test will begin. When the temperature in the heating chamber of the equipment reaches the test temperature, the sample enters the chamber automatically, and the test starts timing. The sample shrinks under heat and generates heat shrinkage force. When the heat shrinkage force reaches the set condition, the sample automatically exits the chamber. The force value is the cold shrinkage force. The equipment automatically records and displays in real time the heat shrinkage force, cold shrinkage force and shrinkage rate of the sample from entering the chamber to the end of the test. After the test, the equipment displays the maximum shrinkage rate, maximum heat shrinkage force, and maximum cold shrinkage force of each group of samples. High-quality products have high transparency and gloss, good sealing, good shrinkage and tightness, and will not be scattered or packaged incompletely. In addition, they can protect the product from being easily broken. Therefore, before we buy shrink film, we must learn more about the relevant content, master the relevant judgment methods, and choose a formal and good responsible manufacturer.
