What is the “Ice Flower “?” Ice Flower ” is essentially a spray-coating process. Think of it as tattooing the bottle – but instead of ink, we use specialized coatings to create the textured effect.
How are “frosted” created?
- Principle of Frosting (frosted) Process
The frosting effect is achieved through chemical etching or physical spraying, creating irregular concave-convex textures on the glass surface. When light hits these textures, it scatters diffusely, producing a (hazy), frosted “ice crystal” visual effect.
- Key Production Processes
(1) Chemical Etching (Primary Method)
Step 1: Surface Cleaning
Ultrasonic or acid/alkali cleaning removes oil and impurities to ensure uniform subsequent treatment.
Step 2: Anti-Etch Coating Application
Acid-resistant ink or protective film is applied to areas requiring smooth finishes (e.g., logos), leaving other sections exposed.
Step 3: Sandblasting or Acid Etching
Sandblasting: High-pressure spraying of fine abrasives (e.g., silicon carbide) onto the glass to create a frosted surface.
Acid Etching: Immersing glass in hydrofluoric acid (HF) or mixed acid solutions to corrode the surface, forming micro-pore textures.
(Acid etching yields finer results but requires strict environmental and safety controls.)
Step 4: Rinsing and Neutralization
Residual acid is thoroughly removed using water and alkaline solutions to halt further corrosion.
Step 5: Secondary Treatment (Optional)
Additional coatings (e.g., electroplating, UV varnish) may be applied to enhance gloss or tactile properties.
(2) Physical Spraying (Cost-Effective Alternative)
Step 1: Frosting Coating Spraying
Matte paint or UV resin containing particles is sprayed onto the glass surface, forming textures after curing.
Step 2: Baking or UV Curing
Heat or ultraviolet light solidifies the coating. Though less durable than chemical etching, this method suits complex shapes.
- Critical Control Points
Texture Granularity: Determined by abrasive size, acid concentration, or coating particles; adjustable per design requirements.
Environmental Compliance: Acid etching requires waste acid treatment; sandblasting demands dust control to meet regulations.
Combination with Other Techniques: Frosting is often paired with foil stamping or screen printing to highlight glossy-matte contrasts.
- Applications
Cosmetic Containers: Widely used for perfume and serum bottles to elevate premium appeal.
Note: Frosted surfaces are prone to fingerprints; design should consider grip areas.
- Comparison with Similar Techniques
Sandblasting: Uniform matte finish without frosting’s irregular textures.
Matte Etching: Smoother(mist-like) effect but lacks three-dimensional depth.
