Made at our plant in Huizhou since 2016. Garbage bag film is a cents-per-bag business, so this grade is built around how far you can stretch it — high let-down, full opacity, no holes at thin gauge.
With refuse sacks, the cost per bag decides the order. The grade has to carry enough pigment to stay opaque at high let-down, without turning the film brittle.
| Carrier resin | PE / LLDPE (works with recycled content) |
|---|---|
| Carbon black content | Economy to high-loading grades, matched to your let-down |
| Standard grades | N4032 · 1209B · E209 — see the full TDS chart |
| Let-down ratio | Tuned for cost per bag at your target gauge |
| Dispersion | Fine — pinholes and gels are the complaint that loses the customer |
| Melt flow (MFR) | Matched to your blown film line |
| Certifications | ISO 9001 / 14001 / 45001 |
Tell us your let-down target and the gauge you run — we will quote a grade that hits your cost-per-bag number.
We tune loading and let-down to your cost-per-bag target rather than selling a premium grade you do not need.
The bag only gets noticed when it fails. Fine dispersion keeps thin-gauge film intact.
No trading-company layer. A firm factory quote and stable pricing across repeat lots.
Run a trial on your own line before you commit. We keep your spec confidential.
Typical refuse-sack applications our black masterbatch is compounded for:
Household and office bin liners in rolls.
Industrial and municipal garbage sacks.
Consumer trash bags with closures.
Black carrier and checkout bags.
Bag film is the most cost-sensitive black application there is, and it is also where the cheapest grade and the right grade diverge most often. Three things decide the outcome:
| Bag type | Typical let-down | Note |
|---|---|---|
| Light-duty refuse sack | 2–4% | Thinnest gauge — dispersion first |
| T-shirt / carrier bag | 2–4% | Handle strength is a loading and dispersion test |
| Heavy-duty refuse / construction bag | 3–5% | Higher carbon for opacity and toughness |
| Industrial liner | 2–4% | Often co-extruded; specify per layer |
It depends on the opacity you need at your gauge. Share the gauge and how dark the bag has to be, and we will tell you the let-down a given loading will support.
In most cases yes. Tell us what share of regrind or PCR you run and we will match the carrier and loading to it. If your market has recyclability targets, note that standard carbon black blocks NIR sorting — we also develop NIR-detectable black formulations. Why black is hard to recycle →
Yes — 1 ton per specification gets you started. Because refuse sack runs are high-volume, we quote a pallet price and a container price so you can see the real volume saving.
Typically 5–10 days to most markets, with let-down guidance for your line.
Tell us what you are running and how much you need. We reply with a firm factory quote — and, if you want to test before committing, a free 1–5 kg sample compounded on your own carrier resin. No obligation.
High-loading economy grades still have to blow clean. This is the line, and the QC that catches gels before you do.
