As today's fashionable consumer goods, cosmetics not only require exquisite packaging, but also provide the best protection for the product during the transportation link or the shelf life. As a well-known domestic testing equipment and testing service provider, it combines cosmetic packaging testing and application requirements to briefly summarize the testing items and testing methods in order to help cosmetic manufacturers and cosmetic packaging suppliers perform packaging inspection and quality control.
After cosmetics are transported, shelf display and other aspects must reach consumers, and good transport packaging is required. At present, the main packaging of cosmetics is mainly corrugated cartons, and the main test indicators are the compressive strength and stacking tests of cartons.
1. Carton compressive strength test
Corresponding introduction is made here with the model ZB-KY carton compression testing machine. The test corrugated box is placed between the two plates of the ZB-KY carton compression testing machine, and the compression speed is set. The pressure at the beginning of the test is based on the crushing pressure of the carton, which is the pressure strength of the carton, expressed in KN. Please note that the preload value (usually 220N) is set according to the test standard.
2. Carton stacking test
During storage and transportation, cartons need to be stacked and placed in the lowest level cartons to withstand a higher number of cartons. In order not to collapse, they must have appropriate compressive strength after stacking. Therefore, stacking and maximum pressure are a double force for testing. Important. The built-in stack test function of ZB-KY can directly give the result of the stack test.
