Fanfold Kraft Paper Folding Machine with C Type Folding Inline

The SD-PF800A converts two kraft paper rolls into a double-layer fanfold cushioning sheet in a single inline process. It feeds the paper from two unwinding stands, performs C-type folding to create a two-layer structure, then applies perforation and final folding to produce a stackable fanfold sheet. This machine enables converters to produce their own paper-based void fill without relying on plastic inserts or third-party suppliers, running up to 800 mm wide kraft paper at 150 m/min.

  • Produces a double-layer fanfold paper cushioning material that replaces plastic foam or bubble wrap without line modifications
  • C-type folding creates a stronger surface layer that resists tearing during packing and shipping
  • Two-roll feeding allows continuous operation with no downtime between rolls
  • Inline perforation and folding complete the process in one pass, reducing handling and labor
  • Stacking via conveyor delivers finished sheets directly to the packing station
Why It Is Specified

Key Benefits

  • Produces a double-layer fanfold paper cushioning material that replaces plastic foam or bubble wrap without line modifications
  • C-type folding creates a stronger surface layer that resists tearing during packing and shipping
  • Two-roll feeding allows continuous operation with no downtime between rolls
  • Inline perforation and folding complete the process in one pass, reducing handling and labor
  • Stacking via conveyor delivers finished sheets directly to the packing station
  • Runs standard kraft paper up to 800 mm wide at 150 m/min, matching high-volume production needs
Where It Runs

Application Scenarios

  • Packaging converters producing fanfold paper for e-commerce fulfillment centers that require recyclable cushioning
  • In-house packaging teams replacing plastic foam inserts with a paper alternative on fragile product lines
  • Fruit, flower and ceramic packers needing a scratch-free, stackable cushioning sheet for high-volume orders
  • Paper mills expanding into finished converted products by adding a folding line to their output
  • Printing houses producing custom paper wrapping sheets with built-in folding for gift and retail packaging

Who It Is For

  • Protective packaging producers adding a paper-based fanfold line to their product portfolio
  • E-commerce fulfillment centers that need consistent, stackable paper cushioning for daily high-volume packing
  • Paper converters looking to add value to kraft paper rolls by turning them into ready-to-use fanfold sheets
  • Manufacturers in markets with plastic packaging restrictions seeking compliant, recyclable alternatives

Problems It Solves

  • Plastic foam inserts are being banned or taxed in key markets, requiring a paper-based replacement
  • Buying pre-made fanfold sheets from third parties removes control over cost, lead time and material quality
  • Manual folding and stacking of kraft paper is slow, inconsistent and labor-intensive
  • Single-layer paper sheets tear easily under pressure during packing and shipping
  • Lack of a reliable inline folding system forces converters to use multiple machines or stop production

Technical Features

  • Two-roll feeding system with independent unwinding stands for continuous operation
  • C-type folding mechanism creates a double-layer structure for enhanced surface strength
  • Inline perforation and folding complete the sheet formation in one continuous process
  • Conveyor-based stacking system delivers finished sheets directly to the packing area
  • Unwinding diameter capacity up to 1200 mm with 3 inch inflatable air shaft
  • Automatic stop at end of run or when stack height is reached
  • Machine built with durable steel frame and precision folding rollers

Compared With the Alternatives

Buying pre-made fanfold sheets

In-house production removes third-party margins and allows on-demand output, but requires holding kraft roll inventory

Plastic foam inserts

Paper fanfold is fully recyclable and meets environmental regulations, though it does not provide moisture barrier protection

Manual folding stations

This machine delivers consistent sheet quality and speed, eliminating worker fatigue and human error

Single-roll folding machines

Two-roll feeding allows continuous operation without roll change downtime

Use Guide

  • Load two kraft paper rolls onto the unwinding stands, ensuring the 3 inch inflatable air shafts are properly inflated
  • Set the target stack height on the conveyor system to match your packing station
  • Verify the C-type folding alignment and perforation depth on the first few sheets
  • Check that the conveyor stack height is consistent and that sheets separate cleanly

Questions About This Machine
