Filler Masterbatch

GSmach provides advanced pelletizing line for all kinds of filler master batch.

We design the extruders for filler masterbatch, according to the output, formula and final application as your request.
Filler Masterbatch are concentrates of CaCO3 or Talc or BaSO4 in a polymer base.


Filler masterbatch is the plastic additives super normal amount of load attached to the resin and made of concentrated body; manufacturing plastic products, do not have to add the plastic additives, but only need to add the corresponding masterbatch can be. Therefore, it is now the most popular plastic additives filled masterbatch.

Due to the emergence of masterbatch, to promote the rapid development of the plastics industry, played a great role. Its main features are: can simplify the production process; mixing of raw materials is convenient, mixing quality is uniform; improve production efficiency and product performance indicators; reduce dust and wear and tear on equipment; reduce the amount of products in the change of color when cleaning screw material; extend the shelf life of the raw material storage and so on.

Filler masterbatch is extensively used across various industries to enhance polymer properties, reduce production costs, and improve processing efficiency.

  • Plastic Bags and Films: Filler masterbatch improves film stiffness and tear resistance while reducing costs.
  • Containers and Bottles: In blow molding applications, filler masterbatch is incorporated into HDPE and PP. It enhances rigidity and reduces material costs.

Addition rate of filler masterbatches in injection & blow-moulding applications can be up to 50 %, however, most usual levels are between 5-30 %.

  • PVC Pipes and Fittings: Used in the extrusion process to produce pipes and fittings, filler masterbatch improves rigidity, dimensional stability, and reduces production costs.
  • Profiles and Panels: Extruded profiles for window frames, doors, and wall panels benefit from enhanced mechanical properties and surface finish provided by filler masterbatch.

Addition rate of filler masterbatches in pipe & sheet applications can be up to 5-40 %, however, most usual levels are between 5-30 %.

  • Mulch Films: Agricultural films for mulching benefit from filler masterbatch, which improves durability, tear resistance, and cost-effectiveness.
  • Greenhouse Films: Used in the production of greenhouse films, filler masterbatch enhances strength and resistance to environmental factors.
  • Packaging Films: Filler masterbatch is used in blown film extrusion to produce various packaging films with improved strength, tear resistance, and reduced costs.
  • Stretch Films: Stretch films for pallet wrapping and securing goods benefit from increased puncture resistance and stretchability provided by filler masterbatch.

Addition rate of filler masterbatches in film applications is 2-20 %.

Processing of Filler Masterbatch

  • There two feeding system:
  • Weight the raw material separately according to the formula
  • Then put all the material into high speed mixer for 5~10minutes mixing
  • Discharge the material into spiral loader
  • Loading the material into the hopper of volumetric feeder
  • Put the raw material into each tank on the ground.
  • Vacuum loader will convey each component into the storing silo.
  • The raw material will fall into the loss-in-weight feeder automatically. The feeding system will feed the material separately into extruder according to your formula setting one the HMI.
