Polypropylene for Spunbond, Fiber and Woven Bags

Fiber, spunbond, BCF, monofilament and woven-bag PP from PetroChina.

Fiber and tape lines run fast, and every break costs output. BASTONE supplies PetroChina polypropylene matched to spunbond, BCF carpet yarn, monofilament and woven bag processes.

Common Problems in Fibers & Woven Bags

What buyers ask us about, and the grades that solve it.

Filament breaks at spinning speed

Ash and gels break fine filaments. PP S2040 states an ash content of 0.0136 percent for spunbond, high-speed spinning and fine fiber.

Recommended grades

A melt flow that does not fit the process

Spunbond, BCF and monofilament need different melt flow. S2040 runs at 37 g/10 min, S2025 at 22.4 g/10 min for high-speed BCF.

Recommended grades

Sacks that split under load

S1003 combines high tensile strength with low ash for woven bags, jumbo bags and FIBC.

Fibers & Woven Bags FAQ

What is spunbond polypropylene?

Spunbond is a nonwoven fabric made by extruding PP filaments and bonding them into a web. S2040 is engineered for spunbond nonwovens and high-speed spinning.

What is the difference between S2040 and S2025?

S2040 has a higher melt flow rate (37 g/10 min) and targets spunbond and fine fiber. S2025 (22.4 g/10 min, high isotacticity) targets high-speed BCF extrusion for carpet backing yarn.

Which grade suits woven bags and FIBC?

PP S1003 under the KUNLUN brand, with high tensile strength and low ash content, is used for woven bags, jumbo bags and FIBC.
