Test Of Tensile Force Of Stretch Wound Film

The mechanical behavior of the wound film will also change when the tensile speed changes. Under normal circumstances, the tensile stress and tensile strength increase with fast tensile speed, while the elongation at break will decrease. Because the tension wound film belongs to viscoelastic material, its relaxation process is closely related to the deformation rate.
Different test and test results may be obtained for the same kind of stretch wound film. External factors related to the accuracy of test data should be fully considered and strictly controlled, especially the subjective external factors, so that test data can be comparable, consistent and accurate. Therefore, the test personnel have a high sense of responsibility, strictly implement the test standards and operating procedures of the stretch wound film, strengthen the daily maintenance, operation and self-calibration of the tensile testing machine and other equipment of the stretch wound film, to ensure that the experiment is in good condition, in order to obtain accurate test data.
