A fiber woven bag is a durable, flexible, and often reusable container made by interlacing strands (tapes, filaments, or fibers) in a crisscross pattern. They are used for industrial, agricultural, and retail packaging, known for high strength, moisture resistance, and tear resistance.
BioGENIE® for Fiber Woven grades
|
Property |
Typical Specification Range |
Importance for fiber |
|
Carrier Resin |
Matched to base polymer (e.g., PE carrier for PE fiber) |
Ensures complete compatibility and dispersion in the final product. |
|
Dosage (Let-down Ratio) |
Typically 1%, depending on required biodegradable period |
Dictates cost-effectiveness and processing parameters. |
|
Physical Form |
Free-flowing pellets, dust-free processing |
Ensures ease of handling, clean processing, and consistent automated dosing. |
|
Melt Flow Index (MFI) |
Close to the base resin MFI |
Guarantees proper dispersion within the extruder without causing processing issues. |
|
Filterability |
Low Filter Pressure Value |
must exhibit low filter pressure values, indicating minimal screen pack build-up and long, continuous spin performance |
|
Particle Size Distribution |
Typically 50 – 60 microns |
Critical for maintaining minimal screen pack changing |
|
Thermal stability |
Must withstand the high processing temperatures of fiber without degrading or burning |
Avoiding decompose additive during extrusion. |
