Laminated Bag Converting Line: From Roll to Ready Bag, All in One

The Turnkey Solution to Industrial Packaging Automation

“Efficiency is no longer optional—it's the foundation of your competitive advantage.”

YIRAN Machinery’s latest laminated bag converting line represents a breakthrough for industrial manufacturers. It transforms coated woven fabric into fully finished bags in one continuous system—cutting, inserting liners, sewing—without operator intervention.

What Makes This Line a Game Changer?

One Line, Full Integration

• Cutting + PE liner inserting + sewing — all automated in a single flow

• Eliminates need for multiple standalone machines

• Reduces manpower and improves synchronization across processes

Flexible for All Bag Types

• Handles laminated woven fabric with or without PE liner

• Supports fertilizer, chemical, construction, and industrial material bags

• Output-ready for printing, stacking, or direct packaging

Built for the Real Demands of Industrial Buyers

“If your production runs 24/7, your machines must too.”

Key Pain Points Solved

• Labor Cost Pressure: Fully automated; reduces manual handling by over 60%

• Inconsistent Quality: PLC control ensures uniform bag size, stitch length, liner alignment

• Production Downtime: High-stability components built for continuous operation

• Material Flexibility: Compatible with multi-layer laminated woven fabric, BOPP, and coated PP sacks

Common Use Cases

• Fertilizer bag manufacturers need dust-proof seams + PE liner options

• Chemical packaging plants require anti-leak finishes with automated volume

• Construction sack producers look for heavy-duty seams + scalability

Control Made Easy

Industrial PLC Touchscreen Interface

• Set bag dimensions, liner length, and stitch parameters in seconds

• Real-time diagnostics reduce troubleshooting time

• Pre-set programs allow quick changeovers between bag types

Global Trust, Proven Impact

“We used to run three machines. Now we use one—and produce more.”

YIRAN's line is currently operational in India, the Philippines, South America, and the Middle East, with clients reporting:

• 30% reduction in production cost

• 50% improvement in cycle time

• Significant drop in human error rates

“Machines don't replace people; they free them for more valuable work.”

Recap – Why This Is More Than a Machine

• One system to replace three processes

• High compatibility with laminated and coated woven bags

• Lower labor cost + higher precision

• Global service support, training, and spare parts

• Ideal for large-scale industrial producers
