A square bottom panel is normally produced as a separate component and sewn to the lower section of the FIBC body. A U-panel extends from one side of the bag through the bottom to the opposite side, creating different requirements for total length, center position, and end allowance.
The DYCBJ-1350 FIBC Cutting Machine can process square FIBC bottom panels and U-panel fabric. Separate dimensional settings should be established for each structure rather than treating them as the same cutting task.
The machine is equipped with automatic web guiding, with a specified correction distance of 300 mm. Before the roll-fed base fabric reaches the cutting area, the guiding mechanism adjusts its lateral position to prevent continuous movement toward one side of the machine.
Automatic web guiding controls fabric position; it does not replace cutting-length settings, roll-tension control, or bag-dimension calculations. Fabric center and edge positions should be checked again when changing the width, weight, or coating condition of the PP woven material.
| Comparison Item | Square Bottom Panel | U-Panel Fabric |
|---|---|---|
| Structure | Separate square component | Continuous U-shaped main panel |
| Main dimensions | Length, width, and seam allowance | Total length, bottom position, and side heights |
| Cutting focus | Four-edge dimensions and corner structure | Center position and length distribution |
| Optional processing | Hole cutting, corner cutting, cold/hot cutting | Length cutting, cold/hot cutting, and folding |
| Subsequent process | Sewing to the lower bag body | Joining with side panels or other bag components |
| Drawing requirement | Finished and cutting dimensions | Developed dimensions and fold-line positions |
The specified cutting accuracy is ±2 mm. Finished-bag dimensions also depend on seam allowances, folding method, and subsequent sewing operations.
When production changes from square bottom panels to U-panel fabric, the target cutting length, roll center, guiding position, and cutting method should be checked again. If a forward-folding or forward-and-reverse-folding module is installed, the folding direction and dimensions must also be confirmed.
The machine provides a cutting-length range of 300–6000 mm. U-panel length should be calculated from the developed drawing rather than only from the finished bag height.
The DYCBJ-1350 supports cold or hot cross-cutting and lists a temperature-control value of 280°C. The cutting method should be selected according to the PP woven fabric structure, edge requirement, and subsequent sewing process.
Coated fabric should be tested with the actual material to inspect edge sticking, thermal deformation, and cut condition. A completely fray-free edge should not be claimed without testing.

This FIBC Cutting Machine is mainly used to produce square bottom panels and U-panel fabric for PP woven FIBCs, jumbo bags, and bulk bags. Automatic web guiding controls the lateral position of the roll-fed fabric before cutting, while the 300–6000 mm length range accommodates different bottom-panel and U-panel dimensions. Hole cutting, corner cutting, cold/hot cutting, and folding can be configured according to the order before the panels enter the sewing process.
The buyer should provide the square bottom panel’s length, width, seam allowance, and opening positions. For U-panel fabric, the developed total length, side heights, bottom dimensions, and fold-line positions are required. Any hole or corner cutting should also be defined within the available 200–600 mm range.
Yes. The PDF specifically states that the DYCBJ-1350 can process square FIBC bottom panels and U-panel base fabric, although each product requires different dimensional and process settings.
No absolute guarantee should be made. Web guiding adjusts the lateral position of the roll material, while panel dimensions are also affected by length settings, fabric stretch, tension, and subsequent sewing.
The rating applies to the reference condition of L=1000 mm. U-panels may require a longer developed length, so the actual production cycle should be confirmed from the buyer’s dimensions.
