PMTEC supplies complete coating machine systems for paper mills — from individual coater heads and film sizers to full turnkey coating lines with engineering, installation, commissioning, and after-sales support.
Whether you are building a new coating line, upgrading an existing one, or solving a specific process problem, PMTEC brings equipment knowledge, application experience, and project management capability together as a single point of contact.
1. Board (Card) Coating Machine
Board coating machines are the core of any large-scale coated packaging production line. They apply pigment coatings — alone or in multiple passes — to paperboard substrates, improving surface smoothness, gloss, brightness, and printability. The coating weight, uniformity, and drying efficiency of the line determine both the quality of the finished board and the running cost per tonne.
Technical Specifications
| Maximum Web Width | 8,000 mm |
| Maximum Speed | 1,200 m/min |
| Max Coating Weight | 30 g/m² per pass (blade) |
| Coating Methods | Combi blade coater, curtain coater, air knife coater |
| Production Mode | On-line / off-line |
Paper Grades Covered
| Grade | Application |
| White Board Paper | Consumer packaging, displays, book covers |
| White Card Paper | Premium packaging, cosmetics, folding cartons |
| Food-Grade White Cardboard | Cups, food service trays, milk carton blanks |
| Kraft Liner Board | Heavy-duty packaging, industrial cartons |
| Art / Coated Printing Paper | High-quality commercial printing, catalogues |
Board coating lines involve high coating weights, wide webs, and significant drying loads. A fragmented supply approach — buying the coater from one supplier, the drying system from another, and the control system from a third — creates integration risk at every interface. PMTEC’s turnkey scope eliminates that risk by maintaining engineering responsibility across all sections through commissioning.
2. Special Paper Coating Machine
Special papers command higher margins because they are more technically demanding to produce. The process window is narrow, and product specifications are strict. Coating systems must be matched precisely to coating chemistry, substrate characteristics, and application requirements.
Technical Specifications
| Maximum Web Width | 8,000 mm |
| Maximum Speed | 1,200 m/min |
| Coating Weight Range | 0.5 – 35 g/m² |
| Coater Types Available | Multi-type combi blade, short dwell, curtain, air knife, comma blade, multi-roll precision metering, mist spray — see Coater Family section |
| Production Mode | On-line / off-line |
Special Paper Grades — Full Coverage
PMTEC can supply coating equipment for the following grade categories, and others on request:
- Thermal paper
- NCR carbonless paper
- Three-anti thermal paper
- Release / silicone paper
- Transfer paper
- Glassine
- Abrasive / sandpaper base
- Filter paper
- Masking paper
- Label paper
- Art / decorative paper
- Barrier / greaseproof paper
- Reflective film base
- Vacuum aluminium-plating base
- Food wrapping paper
- Anti-rust paper
- Cast coated paper
- Tobacco sheet
- Edible wax paper
- Wear / heat-resistant paper
Barrier and functional coatings require compatibility with water-based chemistries and controlled drying conditions. Selection of coating method must consider substrate sensitivity and coating formulation characteristics.
3. Coater Family
The coater head is where coating quality is physically created. Machine width, speed, and drying capacity define the operating range, but coating formation is determined by the coater type.
Technical Specifications
| Maximum Web Width | 8,000 mm |
| Maximum Speed | 1,200 m/min |
| Coating Weight Range | 0.5 – 35 g/m² |
| Production Mode | On-line / off-line |
Coater Type Selection Guide
| Coater Type | Coating Weight | Application |
| Multi-type combi blade coater | 5 – 30 g/m² | Board, art paper, standard pigment coating |
| Short dwell coater | 3 – 15 g/m² | High-speed, lower-weight pigment coating; good formation |
| Curtain coater | 1 – 20 g/m² | Non-contact application; barrier coatings; ultra-sensitive substrates |
| Multi-roll precision metering coater | 0.5 – 10 g/m² | Precision functional coatings; uniform thin films |
| High-speed air knife coater | 2 – 12 g/m² | Smooth, low-weight coverage; release paper, label base |
| Comma blade coater | 1 – 15 g/m² | Viscous functional coatings; adhesive coatings |
| Mist spray coater | 0.5 – 5 g/m² | Ultra-light functional application; surface treatment |
Key advantages across the coater family:
Uniform coating layer — consistent weight across full machine width
Excellent coverage after coating — minimal uncoated spots or streaks
Paint saving — efficient transfer minimises coating waste
Clean operating environment — contained application reduces overspray
Modular design — coater heads can be upgraded without replacing the machine frame
How PMTEC Works With You
PMTEC is not a catalogue supplier. Every coating machine enquiry starts with understanding the mill’s specific situation: the paper grades being targeted, the production volume and speed requirements, the site conditions, the available utilities, and the commissioning timeline. From that baseline, PMTEC develops equipment recommendations, project scope, and budget estimates — and manages the project from contract through to stable production.
Our Project Process

| Grade & Process Review | Analyse target paper grades, coating requirements, and production parameters; advise on equipment configuration and coater head selection |
| Engineering Design | Process design, equipment layout, utility requirements, feeding system design, and control architecture |
| Equipment Supply | Source, inspect, and ship complete equipment package from qualified manufacturers within PMTEC’s supply network |
| Installation | Site supervision for foundation work, mechanical erection, piping, and electrical installation |
| Commissioning | Trial run with target grade; parameter optimisation; draw settings; coating weight calibration; surface quality verification |
| Training | Operator and maintenance personnel training on all systems; documentation package provided |
| After-sales Support | Spare parts supply, technical advisory, and process support throughout production life |
