LLDPE Masterbatch

What Is LLDPE Masterbatch?

LLDPE Masterbatch is a concentrate — pigment or functional additive dispersed in a Linear Low-Density Polyethylene carrier resin — used to color or modify LLDPE parts during processing.

Typical Processing Methods for LLDPE

Blown Film, Cast Film, Rotomolding, Injection Molding.

Grade & Concentration Notes

• Melt-flow matching. LLDPE film lines are sensitive to carrier–host MFI mismatch — a mismatched carrier reduces dart-drop and tear strength before it shows visually.

Metallocene LLDPE (mLLDPE) is more sensitive to additive interactions than Ziegler-Natta grades; declare which you run.

Typical Applications

Stretch film, heavy-duty shipping sacks, agricultural film, freezer bags, rotomolded tanks.
