There are many physical properties of flexible packaging composite films, one of which is puncture resistance. Usually “puncture resistance” or “puncture strength” is used to confirm this performance, The puncture resistance refers to the maximum resistance value generated when the flexible packaging composite film sample is penetrated by a puncture needle with a specified diameter. This test method is widely recognized by the industry and is used frequently!
The puncture resistance of plastic single-layer film or composite film is one of the important physical properties of packaging materials. It is especially important in some special application fields, In the application of separators in lithium batteries, etc., in the field of special application requirements, the puncture strength of the composite membrane must be tested to reduce various uncertain factors inside and outside.

A film is a thin, flexible, transparent sheet made of plastic, adhesive, rubber, or other material. The scientific explanation of thin film is that it is a 2-dimensional material formed by depositing atoms, molecules or ions on the surface of the substrate. Films are used for packaging, and as lamination layers, plastic packaging and plastic packaging products. Its share in the market is increasing.
The separator in the lithium battery needs to withstand a lot of pressure because the separator is sandwiched between the uneven positive and negative electrodes. In order to prevent short circuit, the diaphragm must have a certain puncture resistance. In the battery manufacturing process, due to factors such as uneven electrode surface coating, burrs on the electrode edges, and limited process level in the assembly process, the separator is required to have considerable puncture strength｜Test Methods of Puncture Resistance ASTM D2582
The test method for the puncture strength of the diaphragm: Cut the diaphragm into strips with a utility knife, and the width of the strip diaphragm must be greater than 100mm. Install the test piece with a width of 100mm on the sample film fixing clamp ring. Then use a steel needle with a diameter of 1.0mm and a radius of 0.5mm at the tip to puncture the top at a speed of (50±5)mm/min, and read the maximum load of the steel needle penetrating the test piece. The test generally measures 3 points, and takes the arithmetic mean value, and the number of test pieces is more than 5. Diaphragm puncture strength test method is based on the standard of GB/T 10004-2008 JIS Z 1707:1997
