Machines or workers close it later. They sew, tape, or glue tops shut. Pick this model for fast filling jobs. Bags stay strong when dropped hard.
Multi-wall tools pull several paper rolls together. You set up two to four rolls. Use strong, stretchable kraft paper for jobs. These rolls roll out side by side. You can add a plastic film roll. Place this layer between paper sheets. It stops water, air, and dirt inside.
Each paper roll uses special tension brakes. You adjust tension for every sheet. Bad tension causes bad paper wrinkles. Sheets feed unevenly and break often. Unwind 70 GSM to 120 GSM paper. Roll out paper without stopping.
Glue tools put paste on paper edges. Small wheels apply long glue lines. This paste glues all paper layers tight. Sheets move over special metal plates. Plates fold paper around a center bar. Glue nozzles add resin along side seams. Rollers squeeze seams to build tubes.
Matching paper tension stops inner paper tears.
Step-cut parts prep bag bottoms well. Old cuts slice all layers straight. Step-cut tools make uneven, staggered cuts. Spinning cutter drums use special stepped blades. Blades cut each sheet at different lengths.
This action creates staggered edges on tubes. Outer layers stay longer than middle layers. Inner layers stay shortest of all. Staggered edges create great spaces for glue.
Blades mark paper sheets before forming tubes.
Pull rollers snap paper along marked lines.
Metal fingers turn tube ends sideways quickly.
Spray nozzles put hot glue on steps.
Folding blades bend paper flaps over tight.
Heavy belts press glued flaps together.
Step-cut bottoms leave no open gaps. Each layer glues to its matching sheet. Fine powders cannot leak out corners.
