Calcium Carbonate Masterbatch (CaCO3) for the manufacture of Paper like

Save in paper like manufacturing processes with the Masterbatch (CaCO3) – PLASPER®

The PLASPER® Calcium Carbonate Masterbatch is a mineral modifier with a high, very fine, treated CaCO3 content that has an excellent dispersion in the final product, indicated for direct addition in the processing of polyolefins. The PLASPER® mineral modifier is designed for increasing productivity, reducing energy costs and improving properties of the paper like.


Improvements in productivity 

  • The CaCO3 increases the thermal conductivity of the extruded product, which results in more rapid heating and cooling of the polymer (Fig. 1)
  • Facilitates welding

Improves properties

  • Allows you to achieve the paper effect. Rigidity, smooth feel and memory effect
  • Improves the mechanical properties
  • The CaCO3 mineral MB can be added at high doses 


  • The application of the PLASPER® Masterbatches does not involve any modification 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 60%
