Now, women of all ages will buy some cosmetics for beauty, which will involve the choice of some packaging materials. Many people buy some low-quality products because of their greed for cheap, which results in regret. By learning some skills, you can choose high-quality and inexpensive products.
Selection of cosmetic packaging materials:

Because packaging protects products, packaging materials must have certain strength and elasticity to adapt to certain external shocks, pressures and other shocks during transportation. Different cosmetics use different packaging materials, such as mirror boxes, which have relatively strong impact resistance and will not crack, especially the position of the buckle.
Isolation capability. Because cosmetics need to be used for a long time, it should include the ability to isolate light, water, temperature, etc. For example, foundation make-up has high requirements for water isolation. If there is too much water, the powder will become sticky and not suitable for use. Other cosmetics will change color in places with strong light. In this case, the ability of light isolation needs to be strengthened. Therefore, transparent cosmetic packaging is not suitable.
Sealing performance. Cosmetic packaging must have a certain sealing performance. Only after various environmental changes can it be used for a long time without leakage and deterioration. Like the change of temperature, there will be a strong sense of vibration during transportation, or the impact of loss.
