Product Description
PP Woven Block Bottom Valve Bag for Cement & Dry Mortar
Heat Sealed, Laminated, Produced on W&H Lines
Manufactured on German W&H CONVERTEX valve bag lines – the same machine platform widely adopted by leading global cement producers for premium valve sacks.
Key Product Advantages：
- Strong weather resistance – PP woven fabric with lamination coating performs reliably in high-temperature, high-humidity, and low-temperature environments, meeting storage and transport demands across diverse regions.
- Moisture barrier– coating prevents cement from absorbing humidity during ocean shipping and open-yard storage.
- Micro-perforated for air release – prevents bag burst on high-speed screw packers; air escapes instantly during filling.
- Reliable drop performance – tested per GB/T 9774-2020, meeting strength requirements for cement packaging bags.
- Validated by top Chinese cement groups – supplied to Conch, CNBM and other leading cement producers under the same specification, with tens of millions of bags delivered annually and zero field complaints.
- Traceable data– mill test reports available, with test methods alignable to international standards such as ASTM and EN for customer verification.
