Calcium Carbonates For Polyolefin Extrusion Coating Applications, 2004 PLACE Conference
The use of calcium carbonate in polyolefin extrusion coating applications is now growing rapidly. Improvements
include increased adhesion, lower extrusion temperatures, faster line speed, less printing surface preparation, better
printability, higher barrier properties, longer run times, and better sealability. The proper selection of calcium
carbonate grade and concentrate carrier resin is required to achieve the optimum balance of properties, performance
and total cost.
