Calcium Carbonate (CaCO₃) is one of the most widely used mineral fillers in the plastics industry and has become essential in modern rigid packaging applications. Beyond functioning as a resin extender, Trinetra Calcium Carbonate enhances product performance, improves processing efficiency, and supports sustainability. When incorporated into polypropylene sheets, it delivers higher stiffness, improved impact strength, better thermal properties, and superior print quality—even at high loading levels of up to 40%. Its excellent thermal conductivity enables faster heating and cooling during thermoforming, resulting in increased productivity, reduced shrinkage, and lower energy usage. By replacing a significant portion of resin, Trinetra Calcium Carbonate also provides strong economic advantages and helps stabilize raw material costs. In addition, it offers meaningful environmental benefits, including reduced greenhouse gas emissions. Fully FDA-approved, Trinetra Calcium Carbonate is suitable for food, medical, and other critical packaging applications, making it a smart, versatile, and cost-effective solution for the future of rigid packaging.
