If you are a manufacturer of polypropylene (PP) woven sacks looking for:

  • Lower costs through seal extrusion rather than stitching PP woven sacks
  • Stronger sacks
  • Higher throughput
  • Cost reduction opportunities

Adding Vistamaxx™ propylene-based elastomer (PBE) to a conventional PP formulation can deliver:

  • Opportunities to tailor the coating properties to meet the requirements of end-use applications by blending with PP and polyethylene (PE)
  • Effective seals at very low temperatures (below conventional polymers), increasing line throughput
  • Low material consumption by using blends, coextrusion and downgauging
  • High bond strength for robust packaging solutions – better than homopolymer polypropylene (hPP) and random copolymer polypropylene (RCP)
  • Excellent adhesion without pre-treatment on woven sacks
  • High UV resistance compared with hPP
  • Controlled coefficient of friction (COF) for effective pallet stability
  • Ease of processing on conventional extrusion coating lines

Typical applications:

  • Cement
  • Chemicals
  • Pet foods
  • Sugars
  • Rice and flour
  • Block bottom bags
