Cosmetic Bottle Caps are Electro-Finished: Aluminum exterior, wrapped over a layer of inner plastic. Cosmetic Glass Bottles Electroplate (UV): Compared to printing, the finish is a brighter color. Cosmetic Empty Bottle Spray Painting: Compared to electroplating, the color is more matte. Cosmetic Packaging Bottle Inside and Outside Spray: The spray is applied to the outside of the inner bottle, creating a noticeable gap between it and the outer bottle when viewed from the side, with a smaller spray area on the side view.

Cosmetic Spray Bottle Outer Shell Painting: The painting is done on the inner side of the outer shell, appearing larger from the outside view and smaller in a vertical plane, with no gaps between it and the inner bottle. Cosmetic Set Bottle Anodized with Gold or Silver Plating: It is actually a thin film, and the seams where it joins the bottle can be seen upon close inspection. Empty Cosmetic Bottle Second Oxidation: This involves a second oxidation process on the existing oxide layer, resulting in a glossy surface with matte patterns or vice versa, commonly used for logo creation.

Cosmetic Bottle Injection Molding Color: It involves adding color powder to the raw material during the injection molding process, which is relatively cost-effective. You can also add pearl powder, but adding too much titanium dioxide will turn the PET transparent color into an opaque one. When choosing between glass and plastic for cosmetic packaging bottles, Dr. Packaging suggests opting for glass bottles due to their better sealing properties, recyclable material, and reduced environmental impact. They also effectively ensure the contents remain fresh for extended periods. Particularly for comparative cosmetics, glass bottles are more suitable for packaging.
