Here's how to pick the Right Bag Conversion Line for your needs.
| How to Select Bag Conversion Line Based on Your Requirements | |||
| S/N | Application Scenario | Your Choice | Problems It Solves |
| 1 | Standard woven bags | Cutting & Sewing Machine | Cuts woven fabric to fixed length and sews the bottom, completing the basic process from tubular fabric to finished bag. |
| 2 | Woven bags requiring simple brand or pattern printing | Cutting, Sewing & Printing Machine | Adds basic printing function to cutting and sewing, with single or double-sided options, enabling brand display. |
| 3 | Woven bags requiring moisture and waterproof protection | Cutting, Sewing & PE Liner Inserting Machine | Automatically inserts an inner liner film during cutting and sewing, isolating external moisture to protect the contents. |
| 4 | Woven bags requiring both moisture protection and basic printing | Cutting, Sewing, PE Liner Inserting & Printing Machine | Adds printing function to the cutting, sewing and PE liner inserting process, meeting both moisture-proof packaging and basic branding needs. |
| 5 | Bags with extremely high sealing requirements | Auto Liner Inserting & Hemming Machine | PE liner inserting + ultrasonic sealing, fully seals the bag mouth, prevents liner displacement and interlayer leakage. |
| 6 | Cement bags, dry mortar bags (valve bags) | Auto Cutting and Sewing Machine with “7” Folding Mouth | Forms the bag mouth into a valve shape, allowing the material to automatically seal the mouth during filling, improving filling efficiency. |
| 7 | Square bottom bags or bags requiring higher bottom load capacity | Gusseting Machine | Folds the edges of the tubular fabric inward into an M-shape, increasing the bottom bonding area for better standing stability and load capacity. |
| 8 | Multiple small rolls needing to be combined into a large roll | PP Fabric Upturning Machine | Splices multiple small rolls and rewinds them into a large roll, reducing machine stops for roll changes and improving continuous production efficiency. |
