Cosmetic bottle caps are electroplated: an aluminum exterior is coated with an inner layer of plastic. Cosmetic glass bottle electroplating (UV): it results in a brighter color compared to silk screening. Cosmetic empty bottle spraying: the color is more subdued compared to electroplating. Cosmetic packaging bottle interior/exterior spraying: the spraying is done on the outer surface of the inner bottle, creating a noticeable gap between the inner and outer bottles when viewed from the side, and a smaller spray area on the side view.

Cosmetic Spray Bottle Outer Shell Printing: The printing is done on the inner side of the outer shell, appearing larger in a side view and smaller in a vertical plane, with no gap between it and the inner bottle. Cosmetic Set Bottle Brushed Metal Coating: It's actually a thin film, and upon close inspection, you can find the seams where it's bonded to the bottle. 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 Coloring: This involves adding color powder to the raw material during injection molding, a relatively inexpensive process. You can also add glitter powder, but adding too much talcum powder will turn the PET transparent color into an opaque one. When choosing between glass or plastic for cosmetic packaging bottles, Dr. Packaging suggests opting for glass bottles as they have better sealing properties, the material is easier to recycle and reuse, causing less environmental pollution, and they effectively ensure the contents remain fresh for longer periods. Especially for premium cosmetics, glass bottles are more suitable for packaging.
