Ir al contenido Kangchuang Paper’s precision slitting service converts master rolls of specialty industrial paper — sulfur-free paper, kraft paper, PE coated paper, VCI paper, and release paper — into custom narrow-width slit rolls precisely sized for automated production line feeding, machine-fed packaging equipment, and specialized industrial applications. With slitting capability from 5mm narrow strips to 1,600mm wide rolls and edge width tolerances of ±0.5mm, we supply slit rolls with consistent roll hardness, clean cut edges, and specified core diameters to customers in the USA, EU, and Asia who require custom-width specialty paper that off-the-shelf suppliers cannot provide. Factory-direct from our Dongguan facility — free sample rolls shipped via DHL Express to the United States.
Kraft Paper Strips and Paper Tapes
Precision-slit kraft paper in narrow strips and tape widths for automated packaging, edge banding, labeling machinery, and continuous wrapping equipment — any width from 5mm to 1,600mm with ±0.5mm tolerance on standard and custom core diameters.
Paper slitting is a precision converting process in which wide master rolls of paper are cut longitudinally (along the length of the roll) into multiple narrower rolls of specified widths — simultaneously, in a single pass through the slitting machine. The output is a set of narrow slit rolls at customer-specified widths, each wound onto its own core at controlled tension. For most industrial paper applications, the paper is consumed not from a wide flat sheet but from a roll being fed continuously into automated machinery — packaging machines, labeling equipment, PCB tape-and-reel machines, component taping systems, or heat-sealing equipment. These machines have fixed paper feed widths that correspond precisely to the component or product width they process. A paper roll that is 5mm too wide or too narrow causes the machine to jam, misalign components, or produce defective outputs. This is why custom-width paper slitting is not simply a convenience — it is a production-critical specification.
Paper slitting uses precision-mounted razor blades or rotary shear blades to cut a wide master roll into multiple narrow rolls in a single continuous pass. In razor blade slitting, disposable razor blades are mounted at calibrated positions along the slitting arbor, producing the cleanest cut edge quality for specialty papers where edge fiber contamination could affect end-use quality. In score/shear slitting, rotating upper blades engage with lower anvil rolls in a scissors-like shearing action, handling heavier paper grades above 100gsm more reliably. After slitting, each narrow roll is wound onto its specified core at precisely controlled winding tension using differential rewinding, producing rolls with uniform hardness from core to outside diameter that feed consistently on automated machinery.
Kangchuang Paper specializes in high-quality industrial papers — sulfur-free, coated, release, and anti-rust. Tell us your requirements and we’ll recommend the right grade with fast turnaround.
Our minimum slit width is 5mm, achievable with razor blade slitting on paper grades up to 80gsm. For papers heavier than 80gsm, the practical minimum is 10–15mm due to mechanical stress on very narrow strips during rewinding.
Standard width tolerance is ±0.5mm across our full width range. For precision applications like component carrier tape paper (which typically specifies ±0.3mm), we achieve tighter tolerances with additional blade calibration steps.
Yes. Multi-width slitting from the same master roll is standard — for example, 44mm, 32mm, and 24mm sulfur-free paper rolls slit simultaneously from one master roll in a single production run.
Standard core inner diameters are 3-inch (76mm) and 6-inch (152mm) in paper or plastic cores. Custom core diameters (25mm, 38mm, 50mm, 100mm) are available on request.
Standard lead time is 7–12 business days from order confirmation for in-stock base paper grades. Sample slit rolls (1–2 rolls per width) are produced and shipped within 5–7 business days.
