Feature
PFM Screen has manufactured polyester mesh belts since 1987. Here is what 35+ years of product refinement delivers to your production line.
| ◈ Precision Uniform Aperture |
| Woven on heavy-duty rapier looms with tension-controlled warping, each belt maintains exact, repeatable mesh openings with minimal warp/weft tolerance variation — no loose wires in either direction. Consistent particle classification accuracy is guaranteed across the full belt width and throughout the belt's entire service life. |
| ◈ Thermal Setting for Dimensional Stability |
| Every belt is heat-set under controlled tension (140–200°C) to eliminate weaving stress, realign polymer chains, and lock in the belt's shape permanently. The result: minimal elongation in service, stable tracking on rollers, and consistent width throughout the belt's lifetime — even under high tension and continuous high-speed operation. |
| ◈ US FDA & EU Food Grade Certified |
| All belts are made from 100% first-quality, high-viscosity PET monofilament compliant with US FDA food contact regulations and EU Regulation No. 10/2011 & 1935/2004. SGS test certificates are available on request. The smooth surface and easy-clean properties make these belts the first choice for hygienic food processing environments. |
| ◈ Extended Service Life & Wear Resistance |
| Strong polyester fibers provide excellent stability and wear resistance for significantly extended media life vs. standard-quality competitors. The 3-shed twill weave option delivers even higher mechanical strength for abrasive conditions — reducing replacement frequency and lowering total cost of ownership on your production line. |
| ◈ All Joint & Edge Types Supported |
| Every joining method is available: metallic clipper, staple fastener, integrated spiral ring, pin ring, and seamless (endless). Edges can be resin-sealed, sewn, tracking-guided, or PVC/TPU-wrapped. All joint and edge types apply to both 2-shed and 3-shed belts — in roll fabric or fabricated endless belt form. |
| ◈ Wide Chemical & Temperature Resistance |
| Standard PET belts operate from -75°C to +150°C with excellent resistance to mineral acids and organic solvents. PPS yarn handles up to +250°C. PA (Nylon) for high-alkalinity environments. PP for very high-pH chemical filtration. Hydrolysis-resistant PET for high-temperature, high-humidity conditions up to +160°C. |

Q1: What is a polyester linear screen mesh belt? A polyester linear screen mesh belt — also called linear screen cloth, plain weave filter belt, or polyester monofilament conveyor belting — is a woven belt made from 100% PET monofilament yarn in a precise 1:1 plain weave. This produces uniform, defined mesh apertures for consistent particle separation, filtration, and conveying across demanding industrial environments. PFM Screen manufactures both 2-shed (plain weave) and 3-shed (twill weave) versions in aperture sizes from 0.4 mm to 5.0 mm. |
Q2: What is the difference between 2-shed and 3-shed polyester mesh belts? 2-shed plain weave produces uniform square apertures with high weave stability — best where filtration accuracy and precise particle classification are the top priority, such as food drying, fruit and vegetable washing, and mineral screening. 3-shed twill weave delivers superior dewatering capacity and significantly higher wear resistance, making it better suited to heavy-duty applications such as woodchip drying, MDF/HDF forming, and abrasive mineral processing. At equivalent aperture size, the 3-shed belt dewaters faster and lasts longer under mechanical stress. |
Q3: What aperture sizes are available, and which is right for my application? PFM Screen offers aperture sizes from 0.4 mm to 5.0 mm (400–5,000 µm), in square mesh, rectangular mesh, or custom configurations. General selection guide: ● Fruit & vegetable washing: 500–3,000 µm (square mesh, blue) ● Mineral washing / mining slurry: 400–2,000 µm ● Sludge dewatering (belt press): 400–1,600 µm ● Wood industry / MDF drying: 2,000–5,000 µm ● Nonwoven fabric production: 1,000–3,000 µm Not sure which aperture to select? Send PFM Screen your machine model and material type — we will specify the correct belt within 24 hours. |
Q4: Are PFM Screen linear screen mesh belts FDA-approved and food grade? Yes. PFM Screen's polyester linear screen mesh belts are manufactured from 100% first-quality, high-viscosity PET monofilament fully compliant with US FDA food contact regulations and EU Regulation No. 10/2011 & EC 1935/2004. SGS test certificates are available on request. The smooth woven surface is easy to clean and resistant to product adhesion — ideal for hygienic food processing, drying, and washing applications. |
Q5: What is the operating temperature range? Standard PET polyester linear screen belts operate from -75°C to +150°C. For higher temperature requirements: ● PPS yarn: up to +250°C — for high-temperature industrial drying processes ● Hydrolysis-resistant PET: up to +160°C — for high-temperature, high-humidity environments ● PA (Nylon): up to +120°C — for alkaline environments (pH > 11) ● PP (Polypropylene): up to +90°C — for very high pH or aggressive chemical environments |
Q6: What joint types and edge treatments are available? PFM Screen offers four belt joining options: metallic clipper seam (quick, widely compatible), staple fastener clipper (flat profile for sensitive conveying), integrated spiral ring seam (hygienic, high-tension food-grade), and seamless (endless) (no joint mark for critical filtration). Edge treatment options include: glue sealed edge (resin-sealed, standard), sewn edge (high-durability stitched), tracking guide edge (V-guide or tracking rope), and PVC/TPU wrapping + V-guide (maximum protection for wide, high-speed belts). All combinations are available for both 2-shed and 3-shed constructions. |
Q7: Can PFM Screen manufacture custom polyester mesh belts? Yes. We manufacture belts to any combination of: aperture size (0.4–5.0 mm, square or rectangular), belt width (up to 5.6 m), belt length (any circumference for endless belts), yarn material (PET, PA, PP, PPS, hydrolysis-resistant PET), weave pattern (2-shed or 3-shed), color (blue, white, or custom), and any joint and edge type. To request a custom quote, please provide your machine brand and model, belt dimensions, required aperture size, operating temperature, and preferred joint type. Quote response: within 24 hours. Production lead time: typically 1–3 weeks. |
Q8: Do you supply roll fabric or fabricated endless belts — and what is the lead time? PFM Screen supplies both: roll fabric (hot-melt sealed edges, no joint) for buyers who fabricate belts locally, and fully fabricated endless belts (with selected joint type, edge treatment, and tracking guides installed) ready to mount on your machine. Standard models in stock ship in 3–7 days. Fabricated endless belts with standard dimensions: 2–4 weeks. Fully custom specifications: 3–6 weeks depending on complexity. Worldwide shipping by express courier, air freight, or sea freight. |
