Roll-to-Roll Curtain Coater for Flexible Films & Paper | High-Speed Continuous Liquid Coating Line – Fully Customizable
Product Overview
A curtain coating machine (also known as a curtain coater) is a precision liquid coating system that creates a continuous, falling "curtain" of coating material through a slotted die head. The substrate passes underneath this curtain on a conveyor, receiving a perfectly uniform, bubble-free coating in a single pass.
This technology is widely used for applying:
UV topcoats and sealers on wood (MDF, particleboard, plywood)
Scratch-resistant coatings on PVC flooring and laminate
Primer or adhesive layers on films, paper, and textiles
Functional coatings on metal, glass, and plastic sheets
Packaging: paperboard, folding carton, corrugated (water-based or UV varnish)
Flexible films: BOPP, PET, PE, paper (primer, adhesive, barrier coating)
Building materials: cement board, calcium silicate board, gypsum board
Industrial parts: metal sheets, plastic panels, glass (functional coatings)
Customization Options
We offer complete customization for the curtain coating machine:
Working width: from 300 mm (narrow web) to 2200 mm (large panels)
Curtain type: single curtain or double curtain for two-layer application
Coating head material: stainless steel (standard) or special alloy for abrasives
Conveyor type: PVC belt (for panels) or mesh belt (for air flow drying)
Heating system: electric, oil, or steam for coating tank and head
Viscosity control: manual or fully automatic with online viscometer
Curing tunnel length and lamp type (UV LED, IR, hot air, or hybrid)
Integration with existing sanding, printing, or embossing line
Cleanroom version for optical films and medical coatings
Explosion-proof design for solvent-based coatings

Frequently Asked Questions
Q: What is the difference between a curtain coater and a roller coater?
A: A curtain coater applies coating without physical contact, eliminating streaks and roller marks. A roller coater uses rotating rollers. We can customize either type or a combination.
Q: Can the curtain coater handle both water-based and UV coatings?
A: Yes, the system is fully customizable for water-based, solvent-based, UV-curable, PU, and epoxy coatings. Different material contact parts are used accordingly.
