Rotary Spin Coating System for Pulp Molded Products: Biodegradable Film Precision Application Machine for Sustainable Packaging

Rotary Spin Coating System for Pulp Molded Products: Biodegradable Film Precision Application Machine for Sustainable Packaging

• Composition of Production Line:

This precision line features a servo-driven indexing system, 24 individually programmable stations, high-precision ultrasonic spray or low-flow spray valves for minimal waste, a controlled climate pre-dry zone, a energy-efficient UV-LED curing tunnel (for UV-curable bio-coatings), and a final cooling conveyor.

• Product Description:
  This advanced rotary spin coating line is designed for applying the latest biodegradable, compostable, or UV-curable coatings to premium and sustainable pulp packaging. It focuses on precision application to minimize material usage—a critical cost factor for specialty coatings—while ensuring perfect performance. Ideal for high-value products in the electronics, cosmetic, and organic food sectors.

• Technical Parameters:

• Application:
  Applying ultra-thin, functional barriers and aesthetic coatings to premium pulp molded products requiring home or industrial compostability certifications.

• Customization:
  Highly customizable based on coating chemistry. Options include ultrasonic spray heads for ultra-low viscosity materials, UV-LED curing for instant cure, or NIR for gentle drying of heat-sensitive biopolymers.

• Feature:

  • Precision Application: Ultrasonic spin coating technology drastically reduces overspray and material consumption.

  • Sustainable Focus: Compatible with the latest bio-based and compostable coating formulations.

  • Gentle Curing: UV-LED or NIR options prevent thermal degradation of sensitive pulp substrates.

  • Data Tracking: IoT connectivity allows for monitoring of production metrics and quality control.

• Support and Services:
  Extensive application development support, partnership with coating material suppliers, and remote diagnostics.

• Packing and Shipping:
  High-precision spray valves are shipped in separate, shock-proof packaging. The entire system is covered for dust and moisture protection.

• FAQ:
  Q: Can this line handle very thin, water-based coatings without clogging?
  A: Yes. The ultrasonic spin coating technology is specifically designed for low-viscosity, particle-free fluids and is far less prone to clogging than conventional air spray nozzles, ensuring consistent application and minimal maintenance.
