A woven bag making machine turns PP woven fabric into finished sacks. It cuts, folds, sews, and stacks bags in one continuous line. This equipment is used for cement, grain, fertilizer, and other goods. It works with polypropylene (PP) rolls and keeps output steady. Factories that pack daily products rely on this machine to meet order volumes without adding labor.
This automatic woven bag making machine runs at high speed and needs only one operator. A fully automatic pp woven bag making machine like this reduces manual work and keeps bag sizes consistent.

Working Process of the PP Woven Bag Making Machine
Flow: Roll loading → Feeding → Cutting → Bottom folding → Sewing → Valve forming → Stacking → Counting
1. Roll loading & feeding.Load the PP woven roll. The machine feeds fabric forward with even tension.
2. Cutting.The PLC sets the bag length. A cutter cuts the fabric to the set size.
3. Bottom folding & sewing
The bottom edge is folded and sewn for a strong base.
4. Valve forming
For valve bags, the valve port is formed in the same cycle.
5. Stacking & counting
Finished bags are stacked and counted automatically.
Key Advantages of the Woven Bag Production Line
- Stable Output.The line runs at up to 100 bags per minute. It suits factories that need a steady supply of woven sacks.
- PLC Control System.A programmable logic controller (PLC) controls cutting length, folding width, and sewing position. This reduces human error and keeps bag sizes consistent.
- Wide Size Range.It handles bag widths of 350–600 mm and lengths of 450–910 mm. You can make different bag types without changing the whole line.
- Low Labor Demand.One worker can run the machine after short training. Automatic stacking and counting also reduce manual handling.
- Durable Build.The frame and moving parts are built for long hours in industrial use.
Applications of the Woven Bag Production Line
- Cement Packaging.Woven PP bags are common in cement packing. They are strong, tear-resistant, and hold heavy loads. A woven bag production line that makes valve bags works well with cement filling systems.
- Fertilizer and Chemical Bags.Fertilizer and chemical products need bags that resist moisture and tearing. PP woven bags meet these needs at a low cost per bag.
- Grain and Flour Packaging.Rice, wheat, corn, and flour are often packed in woven bags. The machine can make bags in the right size range for these markets.
- Animal Feed.Feed mills use large numbers of woven sacks every day. A fully automatic pp woven bag making machine keeps up with this demand without bottlenecks.
- Building Materials.Sand, gravel, and other building materials are packed in woven bags. The high tensile strength of PP fabric suits these heavy-duty uses.
