Blown Film

Calcium Carbonate is currently used to enhance mechanical properties and improve productivity in a wide variety of applications, from thin films to thicker sheets.  

Omya Calcium Carbonate can boost the output of compounding and film processing lines through increased thermal conductivity. The high-purity minerals guaranty excellent thermal stability of the films. Well-controlled particle size distribution and excellent coating properties lead to improved impact strength and tear propagation as well as higher stiffness. Enhanced mechanical properties whilst keeping the film weight constant, in combination with increased extruder output and improved thermal efficiency, results in higher productivity and down-gauging potential. Altogether, the introduction of Omyafilm® offers an economically very attractive solution to film producers.
