When developing products, we inevitably need to consider packaging techniques. Packaging techniques are broadly divided into printing techniques and coloration techniques. This issue focuses on the coloration techniques of packaging materials.
Electroplating Aluminum: An aluminum exterior layer wrapped around an inner plastic layer.

Electroplating (UV): UV color treatment on plastic/aluminum surfaces, which results in a shiny appearance compared to spraying. It is commonly used for bottle caps and pumps, and while electroplating on bottles is also possible, it is relatively more expensive.
Spray Coating: Surface treatment on most packaging materials such as plastic, glass, and aluminum using a spray line. Compared to electroplating, spray coating results in a matte finish; it includes several methods such as inner bottle outer spray, outer bottle inner spray, and bottle surface spray.
Frosted Finish: A frosted texture is achieved by rubbing accelerated abrasive particles against the bottle surface to remove rust, burrs, oxide layers, or for surface pre-treatment, which can alter the smoothness and stress state of the bottle surface.
Wire Drawing Gold/Silver Plating: It is essentially a film; you can find the seams on the bottle upon close inspection.
Secondary Oxidation: Performing a secondary oxidation on the original oxide layer to achieve a pattern where a glossy surface is covered with a matte finish or vice versa, often used for logo creation.
Injection Molding Color: Adding pigment powder to the raw material during the injection molding process, which is a relatively inexpensive technique. It is also possible to add pearl powder, or titanium dioxide to turn transparent PET into an opaque color. The ripple effect is related to the amount of pearl powder added.
This article introduces key techniques and methods for coloring packaging materials in the beauty industry. These techniques play a crucial role in product packaging design, affecting not only the appearance and texture of the product but also the market positioning and consumer purchasing decisions. Through these techniques, brands can better express the uniqueness and value of their products.
