When choosing the plastic film tension tester, The first consideration is the difference range of tension required for quality test, which determines the different sensors used and the structure design of plastic film tension tester.
For general soft packaging manufacturers, the tension range of 100N is enough. Usually single-arm design is enough.
Compared with the double-arm structure, the cost is lower. The double Arm structure is suitable for larger pulling force, such as 1T or more.
How to choose the test stroke of the plastic film tension testing machine, according to the performance and requirements of the flexible packaging film. normally the test stroke 600-800mm is enough
If the material elongation exceeds 1000%, the test stroke can be 1000 or 1200 mm.
When repairing, flexible packaging requires a multi-purpose plastic film tension testing machine, with the basis of different fixtures, it can do tensile, compression, bending, tearing, shearing, 180 degree peeling and 90 degree peeling tests.
In addition to the above items, there are some plastic film tension testing machines on the market, because of their high precision sensors (some up to one in 250,000) can also test the friction coefficient.
