An FIBC liner is generally made from plastic film and requires length cutting and end sealing according to the internal bag dimensions. Compared with PP woven base fabric, liner film can be more sensitive to tension, surface sticking, and heating parameters, so feeding, guiding, sealing, and cold cutting must be controlled separately.
The ZNCMJ-2200 FIBC Liner Cutting Machine handles liner material up to 2200 mm wide and combines straight heat sealing with cold cutting to prepare inner liners for installation in FIBCs.
Straight heat sealing creates a linear sealed area across the end of the liner film. Seal formation depends on film material, thickness, number of layers, temperature, pressure, and contact time.
The PDF lists a temperature-control value of 280°C but does not specify the applicable film-thickness range, sealing width, or seal strength. Therefore, 280°C should not be treated as a fixed production temperature for every PE liner. Trials with the buyer’s actual film are required.
| Process Stage | Machine Function | Items to Check |
|---|---|---|
| Roll loading | Pneumatic loading | Roll installation and maximum Ø1100 mm diameter |
| Material travel | Automatic web guiding | Lateral film position and 300 mm correction distance |
| Length setting | 300–4000 mm cutting range | Developed liner length and sealing allowance |
| Straight sealing | Straight heat sealing | Temperature, sealing position, and film bonding |
| Section cutting | Cold cutting | Cut position and finished liner length |
| Material output | Optional conveyor belt | Liner receiving and downstream transfer |
A shaped-sealing module is available when a non-straight sealing profile is required. The shape, dimensions, and sealing position should be confirmed through drawings and samples.
The specified 2200 mm value is the maximum base-material or film width, not the finished liner width. FIBC liner dimensions may also involve gussets, tubular-film construction, side development, and the available space inside the outer bag.
The buyer should provide the PE film-roll width, developed liner dimensions, finished dimensions, sealing position, and gusset information. For tubular film, the roll structure and opening direction should also be identified.
The ZNCMJ-2200 has a specified cutting accuracy of ±2 mm across a length range of 300–4000 mm. This value describes the length-cutting result; it does not mean that sealing position, sealing width, or seal strength has the same ±2 mm tolerance.
Liner length and sealing condition should be inspected separately after changing the film material, target length, or heating parameters.

This FIBC Liner Cutting Machine is mainly used for roll loading, automatic web guiding, straight heat sealing, and length cutting of PE inner liners for FIBCs, jumbo bags, and bulk bags. Its 2200 mm material width and 300–4000 mm cutting range accommodate different developed liner dimensions. For powder, granule, or other industrial-material packaging, the final liner material, thickness, and sealing performance should be determined according to the product and finished-bag test requirements.
| Check Item | Information Required |
|---|---|
| Film material | PE or another heat-sealable film |
| Film structure | Tubular, sheet, or gusseted film |
| Film width | Not exceeding 2200 mm |
| Film thickness | Single-layer thickness and total sealing layers |
| Liner length | 300–4000 mm |
| Sealing type | Straight or shaped sealing |
| Sealing position | Distance from the liner edge |
| Conveying requirement | Whether a conveyor belt is required |
| Acceptance items | Length, sealing appearance, and seal performance |
This cannot be concluded from the PDF. No applicable film-thickness range is provided, so the buyer’s actual film should be tested.
No. The rating applies to L=1000 mm. A different liner length, sealing method, or film condition requires separate cycle confirmation.
No. ±2 mm is the specified cutting accuracy. The PDF does not provide a separate tolerance for sealing position or seal strength.
