1, with a width of 15mm sampling knife, according to different test items to cut the sample, each 5.

2, open the electronic tensile testing machine, select the sample project, and set the corresponding test parameters, sample width, test speed, and so on, and the sample clamping on the electronic tension machine fixture.

3, respectively test tensile strength, elongation at break, thermal strength, composite film stripping force and other tests, Test five times, record each value respectively, and print 5 test average results.

Through the test of the specimen, you can intuitively understandLiquid packaging BagMaterial, material physical properties good and bad directly affect the overall packaging performance of the bag, for example, in the case of internal and external pressure if there is leakage or rupture, so as to avoid in the transport process, the use of the process, due to the leakage caused by the content of pollution, or rupture caused by economic losses.
