What we tune for film

Film lives or dies on a clean bubble. The masterbatch has to disperse fully and not break the blow — at your let-down, on your machine.

Questions buyers ask

Will it run clean on our blown-film line?

We supply high-dispersion grades tuned to your resin blend and let-down. Send your blend and gauge and we'll propose a starting grade plus a sample to run.

Can you hit a target opacity at lower cost?

Yes — we can formulate anywhere in the 10–50% carbon-black range to hit your opacity target, so you pay only for the black you need. Tell us the look you want.

What is the minimum order?

We support trial and small batches, not just full containers. Tell us quantity and we'll quote both a sample and a production lot.

How fast can we get a sample?

Typically 5–10 days to most markets, packed with your let-down guidance so your line can run it directly.
