Calcium Carbonate Barrier Films And Uses Thereof

Patent No. EP1969186 (titled "Calcium Carbonate Barrier Films And Uses Thereof") was filed by Omya on Nov 20, 2006. The application was issued on Apr 24, 2019.

Patent Summary

Barrier films for packaging moisture-sensitive materials like food, animal feed, and pharmaceuticals that have reduced moisture vapor transmission rate (MVTR) while maintaining good sealing and handling properties. The films contain a calcium carbonate (CaCO3) additive in the polyolefin layers. The CaCO3 is blended with the polyolefin resin in ratios of 15-50% CaCO3 by weight. The films can have multiple layers with CaCO3 in each layer. The CaCO3-polyolefin films have lower MVTR compared to polyolefin films without CaCO3.
