How much do you know about cosmetic packaging techniques? In fact, packaging techniques can be mainly divided into two categories: coloring techniques and printing techniques. Today, let's explore the common coloring techniques and surface treatments for packaging materials.
Electroplating (UV)
Electroplating is a process where UV color treatment is applied to the surface of plastic or aluminum materials. The result is typically a shiny, vibrant color that gives a dazzling effect. Compared to spraying, electroplated colors are more brilliant.
Spraying
Spraying involves applying a coating of paint onto the surface of materials like plastic, glass, and aluminum. The result is often a darker, matte color. Compared to electroplating, sprayed colors are more subtle, making them ideal for users who prefer a minimalist style.
Frosted
Frosting is a technique applied to the surface of glass that gives a frosted, matte texture, creating a hazy effect. This technique is commonly used for cosmetic bottle caps or bodies to add a sense of mystery to the product.
Inside Bottle, Outside Spray
Inside bottle, outside spray refers to spraying the exterior of the inner bottle. From the outside, you can clearly see a gap between the inner and outer bottles. The sprayed area is relatively small when viewed from the side, making it ideal for packaging that highlights the design of the inner bottle.
Outside Bottle, Inside Spray
Outside bottle, inside spray involves spraying on the inner side of the outer bottle. From the outside, the sprayed area appears larger, but when viewed from a vertical plane, it looks smaller, with no gap between the inner and outer bottles. This technique is suitable for packaging that emphasizes the outer bottle's design.
Injection Molding Color
Injection molding color refers to adding color pigments to the raw material during the injection molding process. Pigments like pearl powder or titanium dioxide are added to turn transparent PET into an opaque color. The appearance of water ripples depends on the amount of pearl powder added, making it ideal for packaging that requires a unique effect.
These are the common cosmetic packaging coloring techniques! Each technique has its own unique effects and applications. Choosing the right technique can make your cosmetic packaging stand out!
