Bag Types

Three Cement Bag Configurations

Each configuration is optimised for different filling line speeds, closure requirements and brand presentation needs.

Block Bottom Valve

Square base for stable stacking on pallets. Self-closing side valve allows high-speed pneumatic filling. Preferred by large cement manufacturers.

✓ Fills at 1,200–1,800 bags/hour
✓ Excellent stacking strength
✓ Premium BOPP laminated finish
✓ Self-closing valve (no sewing)

Pinch Bottom

Pinched and glued flat bottom. Suitable for semi-automatic filling lines. Widely used for wall putty, tile adhesive, and dry-mix products.

✓ Strong glued seal
✓ Compatible with auto-fillers
✓ Clean dust-free closure
✓ Cost-effective format

Open Mouth Stitched

Traditional open top sack filled by spout and closed with double-stitched top seam. Economical option for smaller cement and building material producers.

✓ Lowest tooling cost
✓ Flat / gusseted bottom
✓ Double or triple stitch
✓ Inner PE liner option

Technical Advantage

Micro-Perforated Fabric for Faster Filling

Cement and dry powder filling lines face a key bottleneck: air trapped inside the bag during filling slows throughput and causes spillage. Our micro-perforated PP woven fabric solves this.

✓ Micro pinholes allow air exhaust during filling
✓ Increases filling speed by up to 30%
✓ No cement seepage through micro pores
✓ Reduces dust at filling station
✓ Available with or without lamination
✓ BIS compliant specifications
