Fanfold Kraft Paper Perforating and Folding Machine
The SD-PF500A converts a reel of kraft paper into fanfolded sheets with perforations in a single automated process. The machine unwinds the paper, applies perforations and folds it into a stack, which is then conveyed to a collection point. This allows a packaging producer to make its own fanfold kraft paper rolls for use in pre-opened bags on a roll, reducing reliance on third-party suppliers.
- Automatically perforates and folds kraft paper into fanfold sheets for pre-opened bags on a roll
- Stacks finished sheets via conveyor for direct collection, reducing manual handling
- Operates at 90 m/min, enabling consistent output for high-volume bagging lines
- Handles kraft paper reels up to 1200 mm diameter and 1 ton weight for long runs
- Built-in unwinding stand supports up to 1 ton, reducing setup time between reels
Why Buyers Choose It
- Manual folding and perforating of kraft paper is slow and inconsistent compared to automated processing
- Buying fanfold kraft paper from suppliers adds cost and delivery delays
- Inconsistent stack height or fold alignment causes jams in autobagging machines
- Lack of in-house fanfold capability limits ability to scale bagging operations
Who Runs This Machine
- Packaging converters that already process kraft paper reels and want to add fanfold output
- Pre-opened bag suppliers needing consistent, in-house production of fanfold kraft paper
- E-commerce fulfilment centres running automated bagging lines requiring reliable roll-fed material
- Sustainable packaging producers replacing plastic or non-recyclable materials with paper
Where This Machine Is Used
- Protective packaging producers making fanfold kraft paper for pre-opened bags used in e-commerce autobag lines
- Paper converters adding fanfold capacity to their existing kraft paper processing line
- Poly bag makers producing pre-opened bags on a roll for 3PLs and fulfilment centres
- Packers replacing plastic or non-recyclable materials with fanfold kraft paper for sustainable packaging

How The Machine Runs
Materials
- Kraft paper reels up to 1200 mm diameter and 1 ton weight
- Perforation and folding suitable for 70-100 gsm kraft paper
- Optional soft white paper backing layer for laminated fanfold liner
Quality Control
- Web guide and magnetic powder brake maintain consistent tension to prevent misalignment
- Perforation and fold accuracy verified during test runs with customer paper
- Conveyor system ensures even stack height and alignment before collection
- Machines are test run with customer paper before shipment to confirm performance
Customisation
- Perforation pattern can be adjusted for different fold spacing and sheet length
- Power supply can be built to the voltage and frequency of the destination country
- Stacking conveyor height and angle can be adjusted for integration with downstream equipment
- Optional roll to sheet cutting unit can be added for further processing
Certifications
- ISO9001:2000 certificate obtained in 2005
- CE certificate obtained in 2006
How It Compares
| Buying fanfold kraft paper from a supplier | In-house production removes supplier margin and delivery delays but requires investment in machine and kraft reel inventory |
|---|---|
| Manual folding and perforating | Automated processing ensures consistent fold alignment and stack height, reducing jams in autobaggers |
| Plastic pre-opened bags | Paper fanfold is recyclable and accepted in markets restricting plastic, though it is less durable in wet conditions |
Running It On Your Floor
- Ensure the kraft reel is securely mounted on the 3 inch inflatable air shaft
- Set the target fold length and perforation spacing on the control panel before starting
- Start the machine at low speed and monitor the first few metres for fold accuracy
- Adjust the conveyor height and angle to match the collection point
- Keep the perforation and folding rollers clean to maintain sharp edges and consistent results
Fanfold Kraft Paper Perforating and Folding Machine FAQ
What paper weight can the machine handle
It is designed for kraft paper from 70 to 100 gsm, suitable for fanfold and pre-opened bag applications.
How fast does it run in production
The machine operates at a maximum speed of 90 m/min, adjustable based on paper type and stability.
What power supply do you build it for
Standard is 380 V three phase, and we can build to the voltage and frequency of your country on request.
What is the footprint and weight for installation planning
The machine is 2800 x 1200 x 1300 mm and weighs 800 kg, so plan a level floor and access for a forklift.
Can it stack the fanfold sheets automatically
Yes, the machine stacks finished sheets via a conveyor system for direct collection.
