Replacing a portion of the resin with a calcium carbonate
concentrate such as PolyCal™ can result
in significant savings depending on current resin pricing and
percentage of concentrate used.

Higher line speeds, increased outputs, better adhesion, Ease of
conversion, improved COF, printability, and better barrier are among
the many performance improvements that are possible with the
addition of PolyCal™.

PolyCal’s are specifically formulated for use in the wide range of
extrusion coating resins currently used in this demanding high
temperature process. PolyCal™ has been blended in at levels
ranging from 5–30%, depending on the application.
What to Expect During Processing
- PolyCal™ concentrate can be added
at levels ranging from 5-30% via side feeders at the hopper or
using central blend stations.
- No changes in temperature profiles are required; however,
optimized performance while maintaining adhesion may be possible
with lower temperatures.
- Higher outputs and line speeds are often realized.
Physical Property Improvements
PolyCal™ improves the coating adhesion of a variety of
substrates, particularly flame-treated, clay-coated board without
primer coating. PolyCal™ also modifies the coating surface which
increases the surface energy and improves the print quality.
Improved sheet feeding and converting performance and higher seal
strengths are often realized. The mineral addition also improves
the barrier properties and reduces both the coating WVTR and OTR.
