What Is the Best Filler for PP Non-Woven Bags?

Q1: What filler is most commonly used in PP non-woven bag production?

A: Calcium Carbonate (CaCO₃) is the most widely used filler because it lowers cost, increases stiffness, and improves dimensional stability during processing.

Q2: Why do manufacturers prefer Calcium Carbonate over Talc?

A: CaCO₃ has better stiffness enhancement and is more cost-effective, making it ideal for mass-produced shopping bags, gift bags, and promotional non-woven bags.

Q3: Can Talc be used in PP non-woven fabrics?

A: Yes. Talc improves surface smoothness, flowability, and fiber uniformity, but it is usually used as a supplementary filler, not the main one.

Q4: How much Calcium Carbonate is typically added to PP non-woven fabric?

A: The usual loading is 5–30%, depending on the required hardness, thickness, and cost targets.

Q5: Does adding fillers affect the strength of non-woven bags?

A: When used at the correct ratio, CaCO₃ can maintain or even enhance the structural rigidity of the bag without compromising performance.
