Great 4.0 Supreme Sheet Fed Non-Crease Paper Bag Machine

The OYANG Great 4.0 is a revolutionary 4th-generation sheet-fed paper bag machine, fully automated and intelligent, designed for high-end gift, luxury, tea, and apparel packaging. Using an exclusive fully automatic U-shape wrapping & double-side center sealing process, it completes paper feeding, rope threading and bag forming in one continuous, synchronized workflow — boosting output by over 200-300% compared to traditional methods. Key breakthroughs include: no-crease bag surface for a premium finish, no bottom-card structure for material savings, and fully automatic rope threading eliminating manual labor. One unit covers multiple sizes and is compatible with 1180 printing presses, cutting equipment costs significantly. Changeover time is reduced from a traditional 8 hours to just 30 minutes. Only 2 operators are needed with a footprint of just 50? — compared to 200?+ and 10+ workers required for equivalent traditional forming + rope-threading production lines. Current output reaches 2,000–2,500 bags/hour (30-45 pcs/min), with potential to scale up to 3,000–3,500 bags/hour. Machine specs: bag width 286–740mm, bag height 510–1,180mm, side width 70–200mm, paper weight 180–300 g/m², total power 56 KW, dimensions 8,355×6,500×2,800mm. Ideal for high-end gift packaging, food packaging, luxury goods, and tea gift packaging.
