High Speed Fanfold Kraft Paper Folding Machine

The SD-PF500B/PF800B turns a kraft paper roll into a stack of fanfolded sheets in a single automated pass. The machine performs perforation, folding and stacking on 40 to 150 gsm kraft paper at up to 200 m/min, producing sheets that are 8 to 15 inches long, with 11 inches standard. Converters use it to make their own paper-based protective packaging instead of buying pre-cut sheets, and it runs on standard kraft rolls from any supplier.

Produces fanfolded kraft paper sheets in one pass without manual handling between steps
Runs 40 to 150 gsm kraft paper, so raw material is widely available and low cost
Automated perforation and folding eliminate hand cutting and folding errors
Stacking via conveyor allows continuous output and easy collection
Speeds up to 200 m/min (150 m/min for model PF800B) match high-volume packing lines

Where It Runs

Application Scenarios

Packaging converters producing fanfolded kraft sheets for e-commerce void fill
In-house packaging teams replacing plastic inserts with paper-based fanfolded sheets
Fruit and flower packers needing consistent, scratch-free wrapping material
Paper mills adding value by converting parent rolls into finished fanfolded sheets
Printing houses producing custom fanfolded paper for branded packaging

Who It Is For

Protective packaging producers adding paper-based fanfold sheets to their product line
E-commerce fulfilment centres needing fast, low-cost void fill for daily high-volume orders
Paper converters looking to automate the production of fanfolded sheets from kraft rolls

Manufacturers of paper-based packaging who want to reduce dependency on third-party suppliers

Problems It Solves

Manual folding and cutting of kraft paper is slow and inconsistent, leading to uneven stack heights
Buying pre-cut fanfolded sheets from third parties increases cost and removes supply control
Plastic-based protective inserts are being restricted or taxed in key export markets
Inconsistent sheet length from hand folding causes misfeeds in automated packing lines
Lack of automation in paper folding leads to operator fatigue and production bottlenecks

Materials It Runs

Kraft paper from 40 to 150 gsm
Perforated kraft paper for fanfolded sheets
Standard paper rolls used in packaging and printing industries

Manufacturing and Process

Load a kraft roll up to 1200 mm diameter onto the 3 inch inflatable air shaft
Engage automatic lifting system to position the roll for unwinding
Set folding length on touch screen, adjust module if needed for 8 to 15 inch output
Start machine at low speed, verify perforation and folding alignment
Adjust tension and speed to match paper grade and target output rate
Folded sheets are automatically stacked via conveyor for collection

Quality Control

Folding length verified against set value during test run on customer's paper grade
Perforation pattern checked for clean breaks and alignment before full production
Stack height consistency measured across multiple runs to ensure even output
Touch screen and inverter tested at full speed to confirm stable operation

Certifications

ISO 9001:2000 certificate obtained in 2005
CE certificate obtained in 2006

Customization Options

Max material width configured to match buyer's stock roll size, commonly 470 mm or 780 mm
Folding length module changed to support 8 to 15 inch output as needed
Power supply built to local voltage and phase on request
OEM badging and manual language available upon request
Stacking conveyor length adjusted for space or integration with downstream equipment

Compared With the Alternatives

Buying pre-cut fanfolded sheets

Converting in house removes third-party margin but requires holding kraft roll stock and an operator

Manual folding and cutting

Automated folding ensures consistent sheet length and stack height, reducing waste and rework

Plastic fanfolded inserts

Paper is recyclable and avoids plastic regulations, though it does not resist moisture like plastic

Other paper folding machines

This machine includes integrated perforation and stacking, while others may require separate equipment

Use Guide

Mount a kraft roll up to 1200 mm diameter and 1 ton on the 3 inch inflatable air shaft
Engage the automatic lifting system to bring the roll into position
Set the desired folding length on the touch screen, change module if outside 11 inch standard
Start the machine at low speed to verify web alignment and folding pattern
Increase speed gradually to target rate, monitor stack height and folding quality
Collect folded sheets from the conveyor and check for consistent length and clean perforation
