Honeycomb Fire Retardant Filter Paper Making Machine
The SD-PH800 converts a reel of flame retardant paper or kraft paper into honeycomb filter paper in a single pass. Unwinding, die cutting, and rewinding occur as one continuous process, allowing a packaging producer to manufacture its own fire-retardant filter paper rolls instead of purchasing them. The machine forms hexagonal cells that maintain structural integrity and are suitable for use in air filtration systems where flame resistance is required.
- Produces fire-retardant filter paper from flame retardant or kraft paper reels, meeting safety standards in industrial or commercial filtration applications
- Unwinding, die cutting, and rewinding happen in one process so one operator can manage the line
- Working speed is adjustable from 0 to 100 m/min, allowing output to match downstream production needs
- Automatic meter counting stops the machine at the set roll length, ensuring consistent roll sizes
- Converting your own paper reels removes the margin paid to a filter paper supplier and reduces reliance on external supply chains
Why Buyers Choose It
- Fire-retardant filter paper is not always available from local suppliers and may have long lead times
- Purchasing finished honeycomb filter paper adds a supplier margin and depends on external delivery schedules
- Manual forming of honeycomb structures is inconsistent and not scalable for production use
- Lack of local production capacity for flame-retardant paper-based filters limits supply chain control
Who Runs This Machine
- Packaging converters that already purchase flame retardant paper or kraft paper in reels and want to add a structured filter product
- Paper mills and trading companies expanding into value-added converting with fire-retardant applications
- Industrial equipment manufacturers integrating honeycomb filter paper into their product lines
Where This Machine Is Used
- Protective packaging producers making fire-retardant honeycomb filter paper for industrial air filtration systems
- Paper converters adding value to flame retardant paper by turning it into a structured filter medium
- Manufacturers of HVAC systems or industrial enclosures requiring compliant, paper-based filter materials
- Facilities in regulated environments needing flame-resistant packaging or filtration media that meet local safety codes

How The Machine Runs
Materials
- Flame retardant paper reels from 70 to 100 gsm
- Kraft paper reels from 70 to 100 gsm
- Wrapping paper and shock absorbing paper
- Fish net paper
- Optional soft white paper backing layer for laminated honeycomb liner
Quality Control
- Web guide and magnetic powder brake maintain consistent tension, ensuring uniform cell formation across the roll
- Meter counter verifies roll length before the roll is completed, reducing variation
- Machines are test run with customer-provided paper before shipment to confirm performance
Customisation
- Cutting mould can be changed to produce different honeycomb cell patterns
- Power supply built to the voltage and frequency of the destination country on request
- Rewinding shaft supplied in 1, 1.5, 2, or 3 inch to match your core stock
- Roll to sheet cutting unit added inline on request
Certifications
- ISO9001:2000 certificate obtained in 2005
- CE certificate obtained in 2006
How It Compares
| Buying finished honeycomb filter paper rolls | Converting in house removes the supplier margin but requires inventory of raw paper reels and a machine investment |
|---|---|
| Plastic-based filter media | Paper honeycomb is combustible but can be made fire retardant; it is more sustainable and accepted in regulated environments where plastic is restricted |
| Honeycomb Paper Cutting Machine | This machine forms the honeycomb web; the cutting machine converts finished honeycomb into sheets or pads |
Running It On Your Floor
- Load a flame retardant or kraft paper reel up to 1200 mm diameter and 1 ton onto the inflatable air shaft
- Set the target roll length on the meter counter before starting the run
- Start at low speed and increase gradually using the inverter until the web tracks steadily
- Inspect the first few metres of honeycomb formation to confirm cell geometry and alignment
- Keep the cutting mould clean of paper dust to maintain sharpness and consistent cuts
Honeycomb Fire Retardant Filter Paper Making Machine FAQ
What paper weight can the machine run
It is designed for 70 to 100 gsm flame retardant paper, kraft paper, wrapping paper, shock absorbing paper, and fish net paper.
How fast does it run in production
Working speed is adjustable from 0 to 100 m/min; the practical rate depends on paper weight and how steadily the web tracks.
What power supply do you build it for
Standard is 380 V three phase, and we build to the voltage and frequency of your country on request.
What is the footprint and weight for installation planning
The machine is 3200 x 1350 x 1300 mm and weighs 1800 kg, so plan a level floor and access for a forklift.
Can it cut finished honeycomb paper into sheets
Roll to sheet cutting is an option on this machine and it can also be matched with our paper wrapper.
Do you hold quality certificates
Wenzhou Snda Machinery holds an ISO9001:2000 certificate obtained in 2005 and a CE certificate obtained in 2006.
