The inner layer contacts cosmetic raw liquids directly while the outer layer serves decorative purposes. This layered layout prevents strong essential oils, acids and active ingredients from corroding the exterior appearance structure.
Made from matched PP and PE materials, the inner lining resists erosion from alcohol, fruit acids and concentrated plant extracts. It avoids swelling, cracking or leakage induced by long-term chemical soaking.
The outer double-layer shell stays resistant to discoloration and deformation caused by volatile ingredients. It maintains delicate high-end texture throughout shelf life, fitting high-concentration skincare and luxury cosmetic positioning.
The inner layer undertakes sealing and anti-corrosion contact with essence liquid, while the outer layer focuses on appearance decoration. It effectively avoids discoloration, paint peeling and deformation caused by essential oil volatilization, presenting more premium texture for luxury skincare products.
Long-term exposure to high temperature, strong ultraviolet light and volatile essential oil gas may cause discoloration or luster decline. Sealed storage in a cool and dry environment can effectively protect the outer surface decorative effect for a long time.
Conventional stock colors have no strict MOQ for small trial orders. For special color matching, electroplating and other special surface crafts, there is a corresponding minimum order requirement, which can be negotiated flexibly according to your actual demand.
