Valve Bag Design

The block bottom valve design is compatible with automatic filling machines. The valve opening allows the filling nozzle to insert quickly, and the bag seals naturally after filling. This design helps improve filling speed, reduce material loss, and keep the working environment cleaner. The bag is suitable for cement plants and packing stations using valve bag filling equipment.

Customization

We support customization of bag size, color, lamination, printing, and valve specifications. Customers can provide artwork or brand requirements, and our team will assist with print layout and sample confirmation. Custom printed valve bags help cement brands improve recognition in local and export markets.

Quality Control

Each production stage—from raw material inspection to weaving, lamination, printing, bag making, and final packing—is checked under our ISO 9001:2015 quality management system. Our in-house lab uses whiteness testers, grammage samplers, electronic scales, tensile testing machines, and air permeability and strength testers to ensure consistent quality.

Packing & Delivery

Bags are packed in standard export bales or on pallets according to customer requirements. We support bulk orders and export shipping for cement groups, distributors, and packaging importers worldwide.
