The main inspection items 

1.Tensile strength
In the tensile test, the maximum tensile stress of the sample until the fracture is the tensile strength. In the academic world, it is called tensile strength. 

2. Elongation rate
The percentage of the ratio between the total deformation of the standard distance and the length of the original offset after the tensile fracture of the sample.

3.Tear strength
It is a term defined in a test method for determining the resistance of a film or sheet to tear resistance.The method is a tear test carried out on a special test machine with a sample of the required crack. 

4.Bursting strength 

5. The thickness 

6. Unit area mass 

7. Coefficient of permeability

Permeability coefficient is also known as hydraulic conductivity.In isotropic medium, it is defined as the unit flow under the unit hydraulic gradient, indicating the difficulty of fluid through the pore skeleton.
