The color of plastics not only determines their appearance, but also affects the function and market competitiveness of the product. Whether it is a food storage container or a household storage box, different colors can convey a unique brand image or meet the personalized needs of consumers. In the plastics manufacturing process, there are many different coloring methods. Here are 10 common plastics coloring processes for you.
Masterbatch Coloring
Masterbatch is a high-concentration pigment or dye that is directly mixed with base plastic particles. It is easy to operate and has good dispersibility. It is one of the most common coloring methods.
Applicable scenarios: injection molding, blow molding and extrusion molding.
Dry Pigment Coloring
The pigment is added directly to the resin in powder form and evenly distributed by mechanical stirring. This method is low-cost, but has poor dispersibility and requires strict process control.
Applicable scenarios: simple plastic product manufacturing.
Liquid Coloring
Liquid pigments are added to the resin through an injection system or direct mixing. Its dispersibility is better than dry powder, but special equipment is required for processing.
Applicable scenarios: transparent or translucent plastics.
Pre-Colored Resin
Manufacturers mix plastic resin with pigment before production and provide it directly to users. This method ensures color consistency, but has low flexibility.
Applicable scenarios: high-end products that require precise color matching.
Surface Coating
Color is applied to the plastic surface by spraying, rolling or brushing. This method is suitable for plastic products with complex shapes, but the color is easily affected by wear and tear.
Applicable scenarios: highly decorative plastics, such as household items or toys.
Dip Coating
Plastic is immersed in a liquid containing pigment to form a uniform color coating. The process is simple and suitable for products with low color requirements.
Applicable scenarios: industrial products or simple plastic parts produced in large quantities.
Co-Extrusion Coloring
In a multi-layer extrusion process, materials of different colors are extruded separately to form independent layers, and finally merged into a whole.
Applicable scenarios: plastic sheets, pipes or special appearance design products.
Cast Film Coloring
Use colorants in the manufacture of plastic film to create uniform color effects.
Applicable scenarios: packaging materials or food storage containers.
Laser Marking Coloring
Use laser technology to burn or discolor the plastic surface to form unique patterns or text.
Applicable scenarios: high value-added products or brand customized products.
Electroplating Coloring
Coat a metal layer on the plastics surface to give it a metallic color or other special effects. This method has high gloss and decorative properties, but the cost is high.
Applicable scenarios: high-end decorative plastics products.
Common Coloring Methods For Daily Plastics
In daily life, the plastics products we commonly see are diverse, bright and long-lasting in color. The following are several coloring methods mainly used in daily plastic products:
- Masterbatch coloring: Applicable to food storage containers and lunch boxes, with uniform color distribution and durability.
- Pre-colored resin: Used in household storage containers to ensure the consistency of product color.
- Liquid coloring: Mostly used for transparent or translucent plastic products, such as drinking bottles or transparent storage boxes.
- Surface coating: Widely used in household plastic products with strong decorative effects, such as children’s products or storage boxes with patterns.
These methods are selected according to product use and cost requirements, providing consumers with rich color experience and high-quality products.
