What a slitter rewinder does
The machine unwinds a wide film roll, slits it into two or more narrower rolls with rotary or razor blades, and rewinds each web at controlled tension. It turns stock rolls into ready-to-use rolls for bag making, printing or lamination.
Specifications
What to specify
| Parameter | Details |
|---|---|
| Web width | The widest roll you need to convert. |
| Slit widths | The finished roll widths required for your bag machines. |
| Roll diameter | Unwind and rewind diameters for your handling equipment. |
| Film thickness | Thin films need gentler tension control. |
| Tension control | Automatic tension keeps roll hardness consistent across the width. |
In the line
Where it sits in the line
After the film line
Wide film is slit into bag-machine widths before storage or delivery.
After printing
Printed rolls are slit to final width and rewound for bag making.
Before lamination
Multiple webs are trimmed to exact width for laminating.
How to choose
How to match a slitter rewinder
List your roll sizes
Jumbo width, slit widths and roll diameters define the machine size.
State the film range
Thickness and material affect blade type and tension control.
Ask for a line proposal
The slitter rewinder is configured with your line and quoted as auxiliary equipment.
Buyers ask
Frequently asked
questions
Why not just buy film in finished widths?
Wide rolls are cheaper and more efficient to produce; slitting lets one stock roll feed several bag widths.
What films can be slit?
PE, PP, BOPP and laminated films are typical; blade and tension settings depend on thickness.
Can it run in line or offline?
Both — standalone units are common, and it can be positioned after printing or the film line.
Is it a separate purchase?
It is auxiliary equipment and can be quoted together with the main line.
