How does filler masterbatch work in nonwovens?
In spunbond and meltblown nonwovens, filler masterbatch helps lower production costs and i

Is it compatible with PP-based nonwovens?
Yes. Most filler masterbatches for nonwoven use a PP carrier for seamless blending and dispersion.

Does it impact air permeability or softness?
High filler loadings can reduce softness and increase fabric density. Balance is key — optimal loading ranges between 5–15%.

What are the main benefits?

• Cost saving

• Increased web weight without additional resin

• Enhanced opacity and whiteness

• Better print adhesion for hygiene and medical products

What fillers are best for this application?
Nano or micro calcium carbonate powders are ideal, as they disperse well and maintain processing speeds.
