2、 Cosmetic packaging strength testing
Strength testing includes indicators such as packaging material tensile strength, composite film peeling strength, heat sealing strength, tear strength, and puncture resistance. Tensile strength refers to the maximum stress value that a material can withstand before breaking Testing can effectively solve packaging damage and breakage caused by external forces due to insufficient mechanical strength of the selected packaging materials. Peel strength, also known as composite strength, is a measure of the adhesive strength between layers in a composite film. If the adhesive strength is too low, it is prone to problems such as interlayer separation and leakage during packaging use. The strength of the heat seal is a measure of the strength of the seal. During product storage and transportation, if the heat seal strength is too low, it can lead to problems such as cracking at the heat seal and leakage of the contents. Puncture resistance is an indicator for evaluating the resistance of packaging to hard object puncture.
The corresponding testing instrument information is as follows:
