A rutile titanium dioxide concentrate in PE or PP carrier, used at 2–10% addition to give opacity and whiteness in blown film, blow moulded bottles and sheet. Supplied as free-flowing granules in 25 kg bags.
What it does: titanium dioxide is the white pigment with the highest refractive index, which is why it delivers opacity at low loading. Rutile grades scatter light more efficiently than anatase and are the standard choice for packaging.

Values stated for standard grades. The datasheet issued with your order takes precedence.
A white opacifier for polyolefin packaging and moulded parts.
| Process | Typical addition | Notes |
|---|---|---|
| Blown film (thin, 20–40 μm) | 4–10% | Thin walls need more pigment to reach full opacity |
| Blown film (thick, above 60 μm) | 2–5% | Opacity builds with wall thickness |
| Blow molding (HDPE bottle) | 3–6% | Balance opacity against impact strength |
| Injection molding | 2–5% | Higher loading raises stiffness and lowers impact |
Rates assume a 60% TiO2 grade.

Rutile has a higher refractive index and scatters light more efficiently, so it reaches the same opacity at a lower loading. It is also more weather-resistant. Anatase is cheaper but rarely used in packaging for those reasons.
The finished part carries roughly 60% of the masterbatch loading. Adding a 60% grade at 5% puts about 3% TiO2 into the film. Confirm the number with a gravimetric check on your own line.
At high loadings, yes. Titanium dioxide particles act as stress points and reduce impact and tear strength. Most film producers stay in the 2–10% range and compensate with a tougher resin grade or a small addition of impact modifier.
It is a reflectance measurement taken on a 2 mm injection-moulded plaque against a standard white reference. Higher numbers look brighter and less yellow. The test method and instrument are stated on the datasheet.
