Strength testing includes the tensile strength of packaging materials, peel strength of composite film, heat seal strength, tear strength, puncture resistance and other indicators. Tensile strength refers to the maximum stress value that the material withstands before breaking. The inspection can effectively solve the packaging damage and fracture caused by external force due to the insufficient mechanical strength of the selected packaging material. Peel strength is also called composite strength, and it is used to detect the adhesive strength between layers in a composite film. If the adhesive strength is too low, problems such as leakage due to separation between layers are likely to occur during packaging use. The heat seal strength is to detect the strength of the seal. During the storage and transportation of the product, once the heat seal strength is too low, it will cause problems such as cracking of the heat seal and leakage of the contents. The puncture resistance is an index for evaluating the puncture resistance of the package.
