Blow Film

Calcium Carbonate Masterbatch (CaCO3) for the manufacture of bin bags

Save in bin bag 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 to increase productivity, reduce energy costs and improve properties.


Economic saving

  • Reduction in energy consumption
  • Reduction in raw material costs of 3% to 20%, depending on the percentage of PLASPER® used
  • Helps reduce thickness
  • PLASPER® concentrates produce a whitish appearance on films without pigmentation, which saves the use of TiO2

Improvements in productivity

  • The CaCO3 increases the thermal conductivity of the extruded product, which results in faster heating and cooling of the polymer (Fig. 1)
  • Improves the processability/transformation and the extrusion performance
  • Considerably increases the speed of the line for faster process times
  • Facilitates welding
  • Improves dispersion
  • Improves the impression of the final product
  • Better stability of the bubble, increased production and easier transformation

Improves properties

  • Improves the anti-blocking effect
  • Improves the barrier effect
  • Increases the dart drop resistance (Fig. 2)
  • Increases resistance to tearing (Fig. 3)


  • 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 50%
