About compostable master batch filler

A compostable masterbatch filler consists of a high loading of compostable-compatible mineral or bio-based fillers dispersed in a biodegradable polymer carrier resin. It is engineered for uniform dispersion during extrusion, film blowing, injection molding, thermoforming, and blown molding processes.

The masterbatch provides:

Improved stiffness and dimensional stability
Enhanced processability and melt strength
Reduced shrinkage and warpage
Better thermal stability during processing
Improved opacity and surface finish
Potential reduction in overall raw material cost

The carrier resin is selected to ensure compatibility with compostable polymers such as:

PLA (Polylactic Acid)
PBAT (Polybutylene Adipate Terephthalate)
PBS (Polybutylene Succinate)
PHA (Polyhydroxyalkanoates)
Compostable polymer blends

Typical filler materials include:

Surface-treated calcium carbonate (compostable-grade applications)
Natural mineral fillers
Bio-based fillers such as cellulose or starch derivatives (depending on formulation)
