Fire Retardant Filter Paper Making Machine
The SD-PH800 converts flame retardant paper or fire retardant paper rolls into honeycomb filter paper in a single unwind, cut and rewind pass. A die-cut blade set scores the web to form a three-dimensional honeycomb structure that can be used directly as filter material. Converters use it to produce their own fire-resistant packaging and filtration media without relying on third-party suppliers, and it runs stock 70 to 100 gsm paper at up to 100 m/min.
- Produces fire-retardant honeycomb paper that meets safety standards for industrial and medical filtration applications
- Unwinding, cutting and rewinding happen in one pass so no intermediate handling is needed
- Runs standard 70 to 100 gsm flame retardant paper, shock-absorbing paper, kraft paper and fish net paper
- Automatic meter counting stops the machine at the set roll length so operators are not tied to it
- Inverter controlled main motor allows stepless speed regulation from 0 to 100 m/min
Key Benefits

Application Scenarios
- Industrial filter manufacturers producing honeycomb paper for HVAC and cleanroom filtration systems
- Packaging converters adding fire-retardant cushioning for electronics and medical device shipments
- Facilities in high-risk environments needing compliant packaging that resists ignition
- Manufacturers of protective packaging for batteries, chemicals and flammable materials
- Paper mills converting raw rolls into finished fire-resistant filter media for export
Who It Is For
- Filter media producers needing in-house production of honeycomb paper for fire-safe applications
- Packaging converters expanding into regulated markets where flame resistance is required
- Electronics and medical device packers handling sensitive components in fire-prone environments
- Industrial suppliers producing packaging for chemicals, batteries and energy storage systems
- Exporters shipping to regions with strict fire safety regulations on packaging materials
Problems It Solves
- Buyers need fire-retardant packaging material but cannot source it reliably from third parties
- Plastic-based cushioning fails to meet fire safety standards in industrial or medical settings
- Manual or semi-automated methods of forming honeycomb paper lead to inconsistent cell structure
- Lack of in-house capability forces reliance on external suppliers with long lead times
- Existing paper lines cannot process flame retardant paper without modification
Technical Features

Compared With the Alternatives
Buying finished honeycomb filter paper rolls
Converting in house removes the supplier margin but requires holding raw material stock and an operator
Standard honeycomb paper machines
This machine is designed for flame retardant paper and can handle higher tension during rewinding for thicker grades
Manual honeycomb forming
The machine ensures consistent cell structure and web alignment that hand work cannot achieve
Plastic-based filter media
Honeycomb paper is combustible but can be made fire-retardant; it is fully recyclable and avoids plastic waste
Use Guide
- Load a flame retardant paper roll up to 1200 mm diameter and 1 ton onto the 3 inch inflatable air shaft
- Set the target roll length on the meter counter so the machine stops on its own
- Set line speed on the inverter, starting slow for a new paper grade then raising toward 100 m/min
- Check the ultrasonic web guide is tracking before running the full roll
- Inspect the die-cut pattern and honeycomb structure on a sample to confirm consistent formation
