What this service is for
A width, an edge and a roll your applicator can run
Slitting looks simple until it runs on your line. Turning a jumbo roll into a width that unwinds cleanly, at the tension your applicator expects, with edges that do not shed and a roll that does not star, is a setup job: blade, tension, core and material all have to agree.
We run slitting and rewinding in the same plant as the die-cutting and lamination lines, which is why a width can be slit, a part die-cut from it, and the whole thing shipped as one order with one set of batch records.

Capabilities
Width slitting
From jumbo roll to the width required by your applicator.
Rewinding
Controlled tension and roll hardness for stable unwind.
Spooling
Spools and small rolls for automated or manual assembly.
Edge quality
Clean edges to reduce burrs, dust and web breaks.
Length control
Custom roll lengths and core sizes.
Labeling
Batch and roll identification for traceability.
How the work is actually set up
What sits behind the service page, stated the same way as on the plant page, so a capacity claim can be checked in one place rather than in five.
Slitting lines
Eight slitting lines cover razor, shear and circular knife setups, from narrow electronics widths to wide industrial rolls. The blade type is chosen against the material, not against whichever machine is free.
Rewinding
Six rewinding lines set roll hardness, tension profile and outer diameter, which is where a stable unwind actually comes from.
Tension and web control
Tension profile is set per material, so a roll is neither soft enough to collapse nor tight enough to telescope or star at the edges.
Spooling and small rolls
Spools and short rolls for automated and manual assembly, on the core and with the tail behaviour your equipment takes.
Edge and dust control
Blade condition, material support and cleanup are what keep cut debris off a finished roll.
The specification items we settle before quoting
| Specification item | How it gets confirmed |
|---|---|
| Material and grade | Confirmed by grade, or by the brand material you hold, because thickness, adhesive and carrier decide the blade and the tension. |
| Width and tolerance | Target width with the tolerance your applicator needs, stated per order once the material is known. |
| Length and outer diameter | Metres per roll and the maximum roll diameter your dispenser, head or feeder can carry. |
| Core | One-inch and three-inch cores are the usual formats, with larger cores and spool bodies for automated feed; the core is agreed against your equipment. |
| Winding direction and tail | Which side faces out and how the tail is secured, so a new roll loads without re-threading. |
| Splice policy | Whether splices are allowed, how many per roll and how they are flagged, agreed before production. |
| Roll hardness | Set per material so the roll keeps its shape in transit and still unwinds without dragging. |
| Labelling and batch coding | Grade, size, length, lot and date on the roll label, tied back to the incoming material batch. |
Nothing in this table is a standing promise. It is the list we work through with you; the answers end up in the quotation and on the work order.
Process
Specification
Confirm material, width, length, core and roll orientation.
Setup
Set blades and tension for the material and width.
First article
Check width, edge quality and roll build.
Production
Run, inspect and pack with batch identification.
What to send with a request
Send what you already have. A partial list still gets a useful answer, and whatever is missing simply becomes the question we ask back.
- The material or brand grade, plus thickness and adhesive if you know them
- Target width and the tolerance your applicator needs
- Metres per roll and the maximum roll diameter
- Core size and the winding direction your equipment takes
- Quantity per order and how often you reorder
- Whether splices are acceptable, and how they must be marked
How the result is inspected and released
First article
Width, edge quality, core alignment and roll build checked before the run is released.
Edge inspection
Checked for burrs, feathering and adhesive squeeze-out, which is where slitting quality shows up first.
Length and weight control
Rolls verified against the stated length by count and weight, so the label is truthful.
Batch record
Incoming material batch, line, setup and roll label linked, so a roll can be traced back without a plant-wide search.
Packing and shipment
- Rolls are wrapped individually so the cut edge and the unwind surface stay protected to the point of use.
- Cartons are packed to a stated roll count and marked with grade, width, length, core and lot.
- Pallets are wrapped and corner-protected; sea freight uses ISPM 15-marked pallet material.
- Humid destinations get moisture protection in the pack, because a damp carton changes how a roll unwinds on Monday morning.
Freight term, routing and destination charges are stated on the quotation. The logistics notes and the technical guides explain how each of those lines is worked out.

Questions buyers ask about Slitting & Rewinding
Can you slit to a width below 10 mm?
In many materials, yes. The minimum width depends on material thickness, adhesive and edge quality requirements; we confirm at review.
Do you supply spools?
Yes. We can rewind to spools or small rolls for automated and manual assembly.
Can you keep the same batch for a production run?
We plan slitting from the same incoming batch where possible and record the batch on the roll label.
Which blade should my material be slit with?
Razor slitting suits thin films and pressure-sensitive materials where a clean, low-force cut matters; shear cutting gives the straightest edge on foams and thick or sticky constructions; circular knives run fast on packaging materials. The wrong blade on the right machine is what produces a ragged edge and a dust problem, so we choose against the material you send.
Why do my slit rolls star or telescope?
Usually a mismatch between roll hardness, tension profile and core, sometimes with a material that stretches. A roll wound too loose collapses at the edge; one wound too tight on a stretchy carrier telescopes when it comes off the shaft. We set the profile per material and confirm the outer diameter against your applicator, which is a setup conversation rather than a complaint after delivery.
Can you keep a production run on one material batch?
Where planning allows, yes, and the batch is recorded on the roll label. Colour, release behaviour and adhesion vary slightly across incoming batches, so for a run that must behave identically on the line we plan the slitting from one batch and say so on the packing list.
What is the narrowest width you can slit?
It depends on thickness, adhesive and the edge quality the application needs. Rather than a fixed minimum, we look at the material and the width together and tell you whether it is a normal setup, a special setup, or the wrong process for that material.
