Construction Materials Packaging Bags
Cement, mortar, tile adhesive, gypsum and dry mixes are packed fast, handled rough, and sold in a market where a torn bag is not just packaging waste — it is product loss and a dust hazard on site. We produce valve sacks and woven bags for construction materials that hold their fill weight and fill cleanly.

How we approach construction material bags
For 25kg and 50kg cement and mortar, the standard answer is a pasted valve sack filled through the valve with no downstream closing step, or a valve woven bag where toughness and cost matter more than paper feel. For tile adhesive and premium dry mixes sold at retail, a printed multi-layer paper sack with a good print face and a block bottom presents far better in a builders' merchant.
What to consider before you order
- Valve sacks fill faster and cleaner than open mouth bags on automatic lines.
- Anti-skid treatment matters when pallets are stacked and shrinkwrapped for storage.
- Cement dust escaping through a seam is a health and safety issue on site, not just a cost.
- Retail dry mixes sell better in a paper sack with a strong print face.
- Humidity protection is worth paying for on long sea routes.

FAQ
Which is better for 25kg cement, a paper valve sack or a woven bag?
Both work, and the choice is usually made by your filling line and your market. Paper valve sacks fill faster and more cleanly and present better at retail; woven valve bags are tougher in rough manual handling and generally cheaper per tonne. Send us a photo of your filler and your current bag and we will quote both so you can compare directly.
Can you supply anti-skid bags for automated palletising?
Yes. Anti-skid treatment on the outer surface stops bags sliding off the pallet during stacking and transport, which is essential for automated palletisers and high stacks. Tell us at quotation stage so it is built into the structure.
