30ml fat body thick base luxury essence glass bottle

This brilliant purple bottle utilizes chrome electroplating on the plastic dropper parts along with gradient spray coating on the glass bottle and single-color silkscreen printing for a dynamic, high-end look.

First, the inner lining, outer sleeve and button components of the dropper assembly are electroplated with a shiny chrome finish. The parts are immersed in a chromium electrolytic bath and an electric current is applied to deposit a polished metallic layer onto the plastic subtrates.

Next, the glass bottle body is coated with a transparent, high-gloss purple gradient spray application using automated pneumatic guns. The gradient fades subtly from rich purple at the base to a lighter lavender hue towards the top. The translucent purple tint allows light to pass through the glass for a vivid glow.

Finally, crisp white silkscreen printing is applied on the lower third of the bottle. Using a fine mesh screen, thick white ink is pressed through a template onto the glass surface. This provides bold, high-contrast branding opportunities.

The combination of gleaming chrome dropper parts, radiant spray-on purple gradient, and contrasting white print creates luxury packaging that catches consumer eyes. The colors pop while the embellishments connote quality and prestige.

In summary, this manufacturing process leverages electroplating, transparent gradient spray painting and precision silkscreening to produce a bottle with stand-out shelf appeal and refined elegance perfect for upscale beauty and cosmetic products.
