5 Reasons to Use Calcium Carbonate Filler Masterbatch in PP Polypropylene Woven Bag​

Highly filler masterbatch contains more than 50 % by weight of filler that is dispersed in a polymer matrix. Different process set-ups are possible depending on the type and amount of filler CaCO3. The most common fillers include calcium carbonate CaCO3 or talcum. CaCO3 Filler masterbatch is primarily used to optimize and increase the stiffness, reduce shrinkage and improve the surface appearance of the final product.

Calcium Carbonate (CaCO3) Filler Masterbatch is one of the most widely used mineral fillers in the plastics industry, and its use in rigid packaging has increased significantly over the years. Once thought of simply as a resin extender, the addition of calcium carbonate Filler masterbatch in plastics has been shown to contribute to increased performance, improved processing, and improved sustainability of the finished part.

Check out five great reasons why you should consider using calcium carbonate filler masterbatch polypropylene pp woven bag for your next project:

PP CaCO3 Filler masterbatch

1. Improved Performance:

The addition of calcium carbonate Filler Masterbatch to polypropylene PP woven bag  has been shown to improve the performance of the plastic across the board. At just an 18% loading, studies performed by MASKA GLOBAL showed that the calcium carbonate filler Masterbatch improved several key properties. Improvements in heat deflection temperature, impact strength, stiffness, barrier properties, and print quality were all observed. In fact, even greater gains were realized at higher loading levels. Calcium carbonate  Filler Masterbatch is currently being used in commercial applications at up to a 40% fill rate all while improving part function.

2. Improved Processing:

The use of calcium carbonate filler masterbatch in polypropylene PP wven bag can help streamline thermoforming applications by allowing the plastic to heat up and cool down faster. The improved thermal conductivity allows for significant energy savings through improved productivity, higher outputs, and faster conversion rates. In addition, faster cooling helps to reduce shrinkage and results in less warping, allowing for greater predictability in the finished part.

3. Economic Advantages:

The resin market can be volatile, and integrating calcium carbonate Filler Masterbatch can protect consumers against unpredictable price fluctuations. The displacement of resin allows for significant raw material cost savings by replacing up to 40% of plastic with price-stable calcium carbonate filler masterbatch. In addition, the improved thermal conductivity, higher output rates and improved conversion rates result in increased operating efficiencies, all of which positively impact the bottom line.


4. Sustainability:

For all of the benefits that plastics afford us in modern society, it comes at a cost and studies have shown that consumers and brand owners are becoming increasingly more concerned with the sustainability of their packaging.  Studies conducted by MASKA GLOBAL have shown that using a 40% loaded calcium carbonate filler masterbatch polypropylene can generate a Green House Gas savings of approximately 23% – and this is before taking into consideration the increased productivity mentioned. 

5. FDA Approved:

Calcium carbonate Filler Masterbatch as a plastics additive is 100% FDA approved, allowing for versatility among applications and use in critical applications in the food packaging foodservice packaging and medical packaging markets.
