White opaque BOPP, also known as pearlized film, and Polypropylene woven bags are products that are almost impossible to produce without Calcium Carbonate. However, Calcium Carbonate is also used in many other PE film applications to improve critical film properties such as tear resistance and of course to reduce costs.
In thin and transparent films the use of Calcium Carbonate was always limited but thanks to the Omyaclear innovation, Calcium Carbonate can now also be used in these films. If you like to know more about how to produce more efficient Polyolefin Masterbatch please read the Omyamax brochure.
