The mechanical performance of cosmetic package plays an important role in the packaging & processing, transportation and shelf life. Its quality directly affects cosmetics safety during distribution. The testing items include: tensile strength & elongation rate, peeling strength of laminated films, heat seal strength, sealing and leakage, impact resistance and surface smoothness, etc.

• A good status of the impact resistance performance will avoid the packaging breakage due to low ductility; and effectively avoid goods damage of low impact resistance and low falling resistance during circulation. Usually, falling dart impact tester is applicable. Take Labthink BMC-B1 Falling Dart Impact Tester as an example, it determines the impact resistance of plastic film by free-falling dart. This is a commonly accepted testing method by cosmetic producers and relevant packaging manufacturers. It’s to test whether the required energy can damage the film specimen under the impact of the free falling dart. If 50% of the specimens damage under regulated condition, estimate the required energy.
