Cosmetic Packaging Bottles with Electrofoil: Aluminum exterior, coated with a layer of plastic inside. Electroplating (UV): Shines brighter compared to printing. Printing: The color appears more subdued compared to electroplating. Outside Printing on Inner Bottle: The spray is applied on the outside of the inner bottle, creating a noticeable gap between it and the outer bottle from the side view, with a smaller spray area. Inside Printing on Outer Bottle: The spray is done on the inner side of the outer bottle, appearing larger from the outside, smaller in a vertical plane view, and without any gap with the inner bottle. Brushed Gold/Silver Coating: Essentially a film, the seam can be seen on the bottle if observed closely. Second Oxidation: This involves a second oxidation on the existing oxide layer, creating a design with glossy areas over a matte finish or vice versa, commonly used for logo creation.

Injection Color: Refers to adding color powder to the raw material during the injection molding process, which is relatively cost-effective. Pearl powder can also be added, but adding too much titanium dioxide will turn the PET transparent color into an opaque one. The sandblasting process on cosmetic empty bottles creates a frosted surface, enhancing the tactile and visual quality while preventing fingerprints and stains, keeping the bottle clean. The transparent process for cosmetic glass bottles maintains the transparency of the glass, directly showcasing the product's original appearance. This technique is particularly suitable for products that aim for a minimalist style.

The semi-transparent coloring technique adjusts the transparency and color of glass bottles to create a unique effect, making them appear more mysterious and attractive. When manufacturing cosmetic glass bottles, material selection is crucial, typically involving high-quality glass materials to ensure product quality and durability. Design considerations should take into account the product's characteristics and image, as well as the practicality and aesthetics of the bottle. The processing technology also affects the appearance and quality of the glass bottle, so the appropriate technique must be chosen based on the product's requirements. Strict quality control is necessary during production to ensure the glass bottles meet the standards.
