Cosmetic Bottle Caps: Electrofoil with an aluminum exterior, wrapped over a layer of inner plastic. Cosmetic Glass Bottles with Electroplating (UV): The finish is brighter compared to pad printing. Cosmetic Empty Bottles with Spray Painting: The color appears more matte compared to electroplating. Cosmetic Packaging Bottles with Internal and External 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 Vessel Internal Spray: The spray is applied on the inner side of the outer vessel, appearing larger from the outside and smaller when viewed in a vertical plane, with no gaps between it and the inner bottle. Cosmetic Set Bottle Anodized and Gold/Silver Coated: It's actually a thin film, and upon close inspection, you can find the seams where it joins the bottle body. 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: This involves adding color powder to the raw material during the injection molding process, which is a relatively inexpensive method. Pearl powder can also be added; however, adding too much titanium dioxide can turn the PET transparent color into an opaque one. When choosing between glass or plastic for cosmetic packaging bottles, PackDoc suggests opting for glass bottles as they have better sealing properties, are made of a material that's easy to recycle, and contribute less to environmental pollution. Additionally, they can effectively ensure that the contents remain unchanged for a long period. Particularly for cosmetics that are highly perishable, glass bottles are more suitable for packaging.
