The principles of cosmetic glass packaging mainly include the following aspects:
Chemical stability: Glass bottles have good chemical stability and are not easy to react chemically with cosmetic ingredients, thus avoiding the problem of cosmetic deterioration.
Transparency: Glass bottles have high transparency and can clearly show the texture and color of cosmetics, giving consumers a sense of luxury and trust.
High and low temperature resistance: Glass bottles have good temperature tolerance and can withstand high temperature disinfection and can be stored in low temperature environments to ensure the stability and safety of cosmetics.
Sealing: Glass bottles have strong sealing properties and can effectively prevent external impurities from entering, ensuring the hygiene and quality of cosmetics.
Environmental protection: Glass bottles can be recycled and reused, without pollution to the environment, and meet the requirements of sustainable development.
