PMC Selection Checklist

Step 1: Define Your Paper Grade

☐

Tissue / Towel High-speed (up to 2,200 m/min), requires SSB triple-layer forming fabric + fine batt press felt

☐

Packaging / Containerboard Medium-high speed, double-layer or SSB forming + heavy-weight press felt (1400-1600 g/m²)

☐

Printing & Writing (Cultural Paper) Requires fine surface forming fabric + low-marking press felt + flat woven dryer fabric

☐

Kraft / Linerboard Heavy-duty double warp dryer fabric + robust forming fabric with high drainage capacity

☐

Specialty / Technical Paper Custom specifications — contact our technical team for tailored recommendations

Step 2: Document Your Machine Parameters

Parameter	Your Value	Why It Matters
Machine Speed (m/min)	________	Determines fabric layer type and stability requirements
Machine Width (m)	________	Fabric width — we manufacture up to 12.5m
Fabric Length (m)	________	Custom to your machine — provide exact measurement
Nip Pressure (kN/m)	________	Affects press felt weight and compaction resistance
Operating Temperature (°C)	________	Dryer fabric material selection (PET vs PPS)
Filler Content (%)	________	Higher filler → higher abrasion resistance needed
pH Range	________	Chemical resistance requirements

Step 3: Select Forming Fabric

☐

Single-Layer Cost-effective for low-speed packaging/cultural paper. 30-45 day life.

☐

Double-Layer Balanced performance for medium-speed machines. 45-60 day life.

☐

2.5-Layer Bridge solution — near SSB performance at competitive price point.

☐

SSB Triple-Layer (Recommended) Best formation quality, longest life (60-90+ days), ideal for high-speed tissue.

Step 4: Select Press Felt

☐

Weight Selection 1200-1400 g/m² (tissue/pickup) | 1400-1600 g/m² (standard press) | 1600-1800 g/m² (high-nip/VALMET OptiPress)

☐

BOM (Batt-on-Mesh) Good void volume, cost-effective for standard applications

☐

BOB (Batt-on-Base) Superior compaction resistance, extended life — recommended for high-nip presses

☐

Chemical Treatment Needed? Anti-contamination | Release coating | Abrasion resistance — specify requirement

Step 5: Select Dryer Fabric

☐

Flat Woven Polyester Smooth surface for fine paper grades. Air permeability: 600-1200 L/m²·s. Max 180°C.

☐

Double Warp Polyester Higher tensile strength for heavy-duty applications. Better dimensional stability.

☐

Spiral Coil (PET/PPS) Maximum permeability (1000-1800 L/m²·s). On-site repairable. Max 200°C (PPS).

Step 6: Supplier Evaluation Criteria

☐

ISO 9001:2015 CertificationQuality management system — non-negotiable for consistent product quality

☐

In-House Laboratory TestingAir permeability, tensile strength, caliper testing — request current test reports

☐

Reference Customers in Your Paper GradeAsk for references running similar machines and paper grades

☐

Technical Support & After-SalesOn-site installation guidance? Performance tracking? Troubleshooting support?

☐

Delivery Lead TimeStandard: 15-30 days. Rush orders: confirm availability.

☐

Minimum Order Quantity (MOQ)Confirm MOQ — we accept single-piece orders for all product lines

Step 7: Request & Compare Quotations

☐

Prepare RFQ with complete specificationsInclude all machine parameters from Step 2 for accurate quoting

☐

Request TCO analysis, not just unit priceCompare cost per ton of paper produced — not cost per fabric

☐

Request sample swatches for evaluationPhysical inspection of weave quality, material feel, and construction

☐

Compare at least 3 suppliersInclude one premium, one mid-range, and one budget option
