Raffia and ropes

Calcium Carbonate Masterbatch (CaCO3) for the manufacture of raffia sacks and bags

Save by using it in the production of raffia sacks and bags and agricultural packaging

The PLASPER® Calcium Carbonate Masterbatch is a mineral modifier with a high, very fine, treated CaCOcontent that has an excellent dispersion in the final product, indicated for direct addition in the processing of polyolefins. The PLASPER® mineral modifier is designed to increase productivity, reduce energy costs and improve properties.


Economic saving

  • Reduction in energy consumption
  • Reduction in raw material costs of 3% to 15%, depending on the percentage of PLASPER® used
  • The PLASPER® concentrates produce a whitish appearance, which saves the use of TiO2

Improvements in productivity

  • The CaCOincreases the thermal conductivity of the molten mixture, which results in more rapid heating and cooling of the polymer (Fig. 1)
  • Better dimensional stability, increase in production and easier transformation
  • Facilitates welding
  • Improves the impression of the final product
  • Improves the processability/transformation and the extrusion performance
  • Improves dispersion

Improves properties

  • Anti-fibrillation effect
  • Improves the mechanical properties

Environmentally friendly

  • Carbon footprint smaller than the virgin polymer
  • Products are more environmentally friendly and sustainable with the use of Masterbacth PLASPER®


  • The application of the PLASPER® series does not require any change to the production process
  • The most suitable dosing systems are:
    • Gravimetric dosing unit
    • Volumetric dosing unit (the best way is to use the feeder at the neck, between the hopper and the extruder)
    • Centralised mixing stations also give good results
  • Dosing: between 3% and 15%


Our products are available in different types of packaging:

  • 25 kg Sacks
  • 1,250 kg Big-Bags
  • 25 Tn Tanker
