Second, cosmetic packaging strength testing
Strength testing includes packaging material tensile strength, composite film peeling strength, heat sealing strength, tearing strength, puncture resistance and other indicators. Tensile strength refers to the maximum stress value of the material before pulling off..?Through the test can effectively solve because of the selection of packaging materials mechanical strength is not enough, and in the external force produced by the packaging breakage and fracture. Peel strength, also known as composite strength, is to detect the adhesive strength between the layers in the composite film, if the adhesive strength is too low, it is very easy to be separated from the layers in the use of packaging and leakage and other issues. Heat seal strength is to detect the strength of the seal, in the preservation and transportation of products, once the heat seal strength is too low, it will lead to heat sealing at the crack, content leakage and other problems. Puncture resistance is an indicator to evaluate the ability of packaging to resist puncture by hard objects.
