30ml short round oil essence glass bottle with a rotary dropper

This bottle packaging utilizes injection molding, spray coating and silkscreen printing techniques to achieve its eye-catching gradient blue color scheme with white and blue accent graphics.

The first step involves injection molding the plastic parts of the dropper assembly, including the inner lining, outer sleeve and button, in white to complement the dominant blue tones of the bottle. Injection molding allows for precise replication of parts with complex shapes in a cost-effective and efficient way. Durable ABS plastic is selected for its rigidity and strength.

Next, the glass bottle is spray painted with a glossy transparent blue finish. A gradual fade from light to dark blue is created from the neck to the base, producing a visually appealing color gradient effect. The glossy finish gives the transparent blue coating an effervescent shine that enhances its aesthetic appeal.

Then, two-color silkscreen printing is applied to add graphic elements in complementary colors. White and blue graphics or text have likely been silkscreen printed onto the transparent blue bottle surface. Silkscreen printing uses a stencil to deposit thick inks evenly onto curved glass surfaces. The negative space graphics formed by the white against the blue bottle helps make the visuals stand out.

The combination of injection molded white parts, glossy transparent blue gradient spray coating and multi-color silkscreen printed graphics come together to produce your desired color scheme and visual appeal. The different techniques provide options to refine aspects like shade and intensity of color, contrast and graphic definition to optimize the overall aesthetic.
