Cement bag making machine

Specialized automated cement bag manufacturing equipment delivers integrated forming solutions for kraft paper multi-layer valve sacks and PP woven cement packaging bags, equipped with PLC control, servo feeding and dual-station unwinding for non-stop roll switching. It unifies flexo printing, laminating, tube forming, bottom pasting and perforation in one workflow, supporting 2–5 layers of kraft paper, PE film and woven fabric composite materials. Built-in photoelectric tracking, automatic edge correction and circulating cutting blades guarantee precise bag dimensions and stable high-speed output. Robust sensor systems monitor tension, length and sealing pressure to lower defective rates. Suited for cement, dry mortar, chemical powder bulk packaging, the equipment cuts labor input, boosts raw material utilization and adapts to customizable 25kg/50kg sack specifications for large-scale construction material production.
