PROFESSIONAL PIGMENT MANUFACTURER
Polyolefin materials mainly include polyethylene (PE) and polypropylene (PP), two of the most widely used plastics in global manufacturing. They are commonly found in packaging films, household goods, injection molded parts, woven bags, pipes, caps, containers, and masterbatch production.
Because of their broad use and large production volume, polyolefins require colorants that offer reliable dispersion, stable processing performance, and cost efficiency.
For manufacturers, selecting the right pigment for PE and PP is not only about shade — it also affects migration resistance, weatherability, heat stability, and long-term product appearance.
Unlike engineering plastics, polyolefins have relatively non-polar polymer structures. This means pigment selection must focus on compatibility and dispersion behavior.
Key challenges include:
Using the wrong pigment may result in streaking, blooming, poor opacity, or unstable shade during processing.
| Application | Resin Type | Key Requirements | Recommended Pigment Focus |
|---|---|---|---|
| Packaging Film | PE | Migration resistance, food contact, transparency control | Organic pigments |
| Injection Molded Parts | PP | Heat resistance, color consistency | Organic / Inorganic pigments |
| Household Goods | PP / PE | Cost balance, brightness | Economical pigments |
| Woven Bags | PP | UV stability, outdoor durability | Weather-resistant pigments |
| Pipes & Containers | HDPE / PP | Long-term stability | High fastness pigments |
| Masterbatch | PE / PP Carrier | High dispersion, tint strength | Easy-dispersing pigments |
Organic pigments are commonly selected when bright shades and strong color strength are required.
Typical uses:
Inorganic pigments are preferred when durability, opacity, and weather resistance are more important than brightness.
Typical uses:
Black and white are among the highest-volume colors in polyolefin production.
Before choosing pigments for polyolefin systems, buyers should evaluate the following:
| Factor | Why It Matters |
|---|---|
| Heat Resistance | PP processing temperatures can exceed 220°C |
| Migration Resistance | Important for films, toys, packaging |
| Dispersion Quality | Impacts surface finish and consistency |
| Lightfastness | Required for outdoor applications |
| FDA / Food Contact | Needed for packaging markets |
| Cost Efficiency | Critical in high-volume production |
| Material | Common Process | Typical Temperature |
|---|---|---|
| LDPE | Film Extrusion | 160–220°C |
| HDPE | Blow Molding | 180–240°C |
| PP | Injection Molding | 200–260°C |
| PP Raffia | Extrusion | 220–280°C |
Pigment heat stability should always exceed actual processing temperature with safety margin.

Pigments with strong heat resistance and good dispersion are generally preferred because PP is processed at relatively high temperatures.
Yes. Many organic pigments are widely used in PE film applications when migration resistance and compliance requirements are considered.
Poor dispersion may cause streaks, color inconsistency, or surface defects in final plastic products.
PP usually requires higher heat resistance due to higher processing temperatures, while PE applications often focus more on flexibility and migration control.
Yes, but weather resistance and UV durability should be evaluated carefully depending on exposure conditions.
