Flexible Intermediate Bulk Containers (FIBCs) and PP woven sacks are the backbone of bulk materials transport in chemical, agricultural, and manufacturing industries. However, once these industrial bags reach the end of their lifecycle, they require proper reprocessing. Mechanical recycling converts this post-industrial scrap into premium PP granules.
The Recycling Workflow for PP Sacks
- Collection & Inspection: Sourcing clean, single-polymer PP bulk bags directly from industrial sites to ensure material purity.
- Shredding & Size Reduction: Woven structures are shredded into fine strips and flakes using heavy-duty granulators.
- Super-Washing: Flakes undergo dynamic friction washing to remove dirt, residual product powders, and chemical residues.
- Melt Extrusion & Pelletizing: Flakes are melt-extruded with fine filtration meshes to remove trace particulate matter, producing uniform reprocessed PP granules.
Industrial Reintegration
The resulting recycled polypropylene granules are utilized to manufacture new industrial straps, structural items, and low-viscosity molded components, reinforcing a circular packaging loop.
