“To many people packaging is just a bag. To us it is a craft — bags are all we make, and we make them properly.”

Square-Bottom Valve Bags
One sack construction, three export markets. The three bags on this page are the same family of square-bottom valve sack — a tile adhesive printed in Cyrillic for a Russian-speaking market, an interior putty printed in English and Chinese for Malaysia, and a cement sack for an African brand.
That is the point of this bag: a heavy composite woven shell, a pasted square bottom that stands up on the pallet, and a print face good enough to carry a full brand story — logo, product line, coverage figures, application photos and net weight. Bag size, fabric weight, liner and colour count are all made to order, and sampling starts from a single piece.
- ✔ Square bottom — the pack stands on shelf and pallet instead of slumping
- ✔ Multi-language print — Cyrillic, English, Chinese or any combination on one face
- ✔ Heavy composite woven — thicker fabric for mortar, cement and dense putty powders
- ✔ Sampling from 1 pc — trial the print and the size before committing to a run
