Surface Deep Processing Techniques — Six Ways to Make Your Bottle More Than Just a Container

From classic solid colors to tactile embossing, we offer a complete range of bottle surface decoration solutions tailored to different brand positioning and budget requirements.

Technique 1: In-Glass Coloring

Principle: Metal oxides are added directly during the glass melting stage, coloring the entire bottle body. The color is permanent—fade-proof and non-peeling.

Applications: Alcoholic beverages, food products, and other goods 

Technique 2: Spray Coating

Principle: Automated spray equipment atomizes enamel or colored paint evenly onto the bottle surface, followed by high-temperature curing. PLC control and bottle rotation ensure full, uniform coverage.

Achievable Effects:

Matte finish

Glossy color

Metallic effect

Applications: Premium spirits, perfumes, and home fragrances

Technique 3: Silk Screen Printing

Principle: Ink is forced through a screen mesh onto the bottle to create logos, text, or patterns. Single-color printing on cylindrical bottles is completed in one pass; multi-color requires registration.

Ink Options:

UV ink — strong adhesion, resistant to alcohol wiping, slightly raised texture

Air-dry ink — lower cost, may wear over time

Applications: Brand names, capacity markings, basic decoration

Technique 4: Decal Application

Principle: Pre-printed decals are activated in water and applied manually or mechanically to the bottle, then fired in a kiln at high temperature to permanently fuse the pattern.

Advantages:

Suitable for irregularly shaped bottles

Rich colors with high detail reproduction

Can be combined with spray coating, hot stamping, etc.

Applications: Complex patterns, gradients, figurative or landscape designs

Technique 5: Hot Stamping (Gold/Silver)

Principle: A base adhesive layer is first screen-printed, then a heated die (approx. 200°C) presses metallic foil onto the designated area, transferring a metallic finish.

Characteristics:

Delivers a premium metallic luster

Colors limited primarily to gold and silver (not customizable)

Commonly used to highlight logos and key text

Applications: Brand identity reinforcement, premium gift packaging

Technique 6: Embossing / Relief

Principle: Decorative patterns are engraved directly into the mold during design phase, forming raised or recessed textures in a single molding cycle—permanent and wear-resistant.

Characteristics:

Premium tactile feel, enhances brand recognition

No additional post-processing cost (integrated in molding)

Can be combined with spray coating for enhanced visual contrast

Applications: Exclusive bottle designs for premium brands, anti-counterfeiting features
