1. Tensile test: A test method for determining the material properties under tensile load under axial load. The data obtained from the tensile test can be used to determine the elastic limit, elongation, modulus of elasticity, proportional limit, area reduction, tensile strength, yield point, yield strength, and other tensile properties of the material. Creep data can be obtained from tensile tests conducted at elevated temperatures.
2, tear test: can get tear load, tear strength.
A, right angle tear: In order to facilitate the opening of the package, a right angle notch is often cut at the edge, and the test of the right angle tearing performance is made according to the requirements of some product standards and the needs of the customer's enterprise.
B. Pant-type tearing method is a kind of test method for tear resistance of plastic film and sheet. It is the force required to test the tearing of the incision after the material is pre-cut.
3, peel test: can get the peeling force, zui small force. The parameters mainly correspond to the head and tail. Conventional 90 degree and 180 degree peeling, mainly to determine the two different materials bonded together to be opened with more than a large value.
4. Sealing test: The sealing strength can be obtained by the sealing test. This test is related to the width and thickness of the sample.
Probiotic
Probiotics are a class of active microorganisms that are beneficial to the host by colonizing the human body and changing the composition of the flora in a certain part of the host. By regulating the immune function of the host mucosa and system or by regulating the balance of intestinal flora, promoting nutrient absorption and maintaining intestinal health, resulting in the production of single microorganisms or mixed microorganisms with well-defined composition that are beneficial to health.
