Color Spray
Color spray for plastic, metal, and glass packaging involves applying a fine mist of colored lacquer or coating to the outer surface of containers using automated spray systems. During production, color spray creates a consistent visual layer that can range from transparent tints to opaque finishes, gradients, or soft-touch textures. This process is widely used to elevate product aesthetics and brand perception in cosmetic, personal care, and luxury packaging sectors.
Advantages
Versatile Surface Options
Enables a wide range of finishes, including glossy, matte, frosted, metallic, and gradient effects.
Customizable Design
Supports full or partial coverage, multi-color layering, and clear windows through masking techniques.
Material Compatibility
Can be applied to glass, plastic, and metal surfaces with appropriate surface preparation.
Lower MOQ Flexibility
Color spray is more flexible and can support smaller production runs as compared to in-mold integrated color applications.
Process
Color spray for plastic, metal, and glass packaging follows a precise, multi-step workflow to ensure a smooth, lasting decorative finish.
Design & Finish Specification
The process begins by defining the desired color, finish (e.g., matte, glossy, frosted), transparency level, and any masking or special effects such as gradients.
Masking (If Required)
Custom masking tools or films are applied to designated areas to create clear windows, multiple colors, or precise pattern boundaries.
Finish Application (Topcoat)
A secondary spray is used to apply the desired surface finish, such as matte, glossy, satin, or soft touch. This topcoat not only defines the final surface effect but also serves as a protective layer to improve scratch resistance and overall longevity of the color.
Demasking (If Required)
After curing, any masking is removed, and minor imperfections may be corrected through manual touch-up or rework if needed.
Post-Treatment and Packaging
Optional enhancements such as anti-scratch treatments or gloss intensifiers may be applied. Approved items are then cleaned (if needed) and carefully packed for shipment or additional decoration steps.
Following these steps, color spray delivers rich and versatile finishes that can be customized for each product’s unique aesthetic.

Surface Preparation
Items are thoroughly cleaned to remove dust, grease, and residues. For plastic materials, surface activation (e.g., flame or corona treatment) may be performed to enhance adhesion.
Spray Application
Using automated spray booths, a fine mist of coating is applied in controlled layers to ensure even coverage and accurate color density. Depending on the desired tone and opacity, the spraying process may be repeated multiple times to achieve the final effect.
Curing & Drying
Sprayed parts are conveyed through heated ovens or UV chambers to cure both the color and finish layers. This process hardens the coating and locks it permanently onto the substrate.
Quality Inspection
Finished products are inspected for evenness, coverage consistency, color accuracy, coating adhesion, and surface texture to ensure they meet visual and performance standards.
Applications
Color spray is widely used in cosmetics, personal care, home care, wine & spirit, and pharmaceutical packaging for its ability to enhance shelf appeal and reflect brand personality.
