Made at our plant in Huizhou since 2010. We compound black for mulch and silage film that is blown thin: even opacity at low gauge, no gels, and enough carbon to last the season in the field.
Mulch film is sold by area, so it gets blown thinner every year. The thinner the gauge, the more a gel or an undispersed particle shows up and tears.
| Carrier resin | LDPE / LLDPE (EVA blend on request) |
|---|---|
| Carbon black content | Set for opacity and field life at your gauge |
| Dispersion | Fine and even — gels and specks are tear starters |
| Melt flow (MFR) | Matched to your blown film line and BUR |
| Opacity | Balanced so the film blocks light at your target thickness |
| Certifications | ISO 9001 / 14001 / 45001 |
Send us your gauge, BUR and target season length — we will match a grade and send film-grade sample.
Holds opacity and strength as you blow thinner, so you are not over-engineering the film.
Carbon loaded for a full season in direct sun, not just for a black appearance.
No trading-company layer. A firm factory quote and a faster answer.
Blow a trial roll on your own line before you commit. We keep your spec confidential.
Typical agricultural film applications our black masterbatch is compounded for:
Row-crop ground cover that suppresses weeds and holds moisture.
Black film for fodder storage where opacity matters.
Interior floor film and light block layers.
Long-life cover film for permanent plantings.
That depends on your resin, line and BUR. Tell us the gauge you want to hit and we will say honestly whether a standard grade works or we need to tune the loading and MFR for it.
Opacity is a function of carbon loading and thickness together. We set the loading so the film reaches full light block at your target gauge.
One ton per specification. Film makers typically blow a trial roll first, then order by the container once the gauge and opacity hold.
Typically 5–10 days to most markets, with let-down guidance for your film line.
