High melt-curtain heat
Molten polyethylene extrusion runs hot, so pigments must resist shade shift and decomposition in the high-temperature melt curtain.
Applications
Pigments for Extrusion Coating
Pigment recommendations for extrusion coating with technical checks and export enquiry support.
Extrusion coating applies molten polymer, usually polyethylene, onto paper, board or film at high melt temperatures and fast line speeds, so pigments must be highly heat-stable to survive the hot melt curtain without shade shift and must disperse fully to avoid specks on thin coatings. Source From India supplies extrusion-coating grades, typically via masterbatch, engineered for clean dispersion and heat resistance. Buyers should confirm stability at high melt temperatures, freedom from specking on thin films, migration resistance for packaging and food-contact compliance where needed, and consistent color at high throughput. Uniform, speck-free color is essential on visible packaging and laminate surfaces.
At a glance
What Pigments for Extrusion Coating covers
Speck-free thin films
Thin coating layers show any undispersed particle, so fully dispersed grades and masterbatch prevent specks and pinpoint color defects.
Migration and food compliance
Food and packaging coatings need low-migration pigments meeting contact regulations so color stays bound in the extruded polymer layer.
High-speed color consistency
Fast lines demand grades that hold uniform shade and strength at high throughput without drift across long production runs.

Answers
Pigments for Extrusion Coating — frequently asked questions
Why is heat stability vital in extrusion coating?
The process lays down a molten polymer curtain at high temperature onto substrate, so pigments must resist thermal shade shift and decomposition during that brief but hot exposure. We supply heat-stable grades, usually as masterbatch, so extrusion coatings hold consistent color without darkening at line temperatures.
How do you avoid specks in thin coatings?
Extrusion coatings are thin, so any undispersed pigment shows as a visible speck. We supply well-dispersed grades and masterbatch that distribute fully in the polyethylene melt, so packaging and laminate surfaces stay smooth and speck-free even at high line speeds.
Are your pigments suitable for food packaging coatings?
For food-contact extrusion coatings we supply low-migration grades that meet relevant compliance requirements and stay locked in the polymer layer. Share your regulatory and end-use targets and we recommend pigments balancing migration limits, heat stability and the color consistency packaging graphics demand.
Do you supply masterbatch or raw pigment?
We supply bulk organic pigments for masterbatch producers and coaters, focusing on heat-stable, speck-free grades for extrusion. Many buyers convert these to masterbatch for clean melt dispersion; we advise on grades matched to your carrier resin and processing conditions.
