Precision Barrier Coating Line for Pulp Molded Products - Ultra-Low WVTR & OTR Coating Application

Precision Barrier Coating Line for Pulp Molded Products - Ultra-Low WVTR & OTR Coating Application

Composition of production line
This system features a servo-driven precision indexing table, a vacuum-fixtured spin coating station, a metered coating dispensing system, a multi-stage drying zone (IR & Convection), and an integrated quality control inspection system. All controlled by an advanced industrial PC with SPC data logging.

Product Description
This precision barrier coating line is designed for manufacturers requiring the highest levels of barrier performance, such as very low Water Vapor Transmission Rate (WVTR) and Oxygen Transmission Rate (OTR). It offers unparalleled process control to apply and cure high-performance coatings uniformly, making pulp mold a viable alternative for packaging sensitive foods, electronics, and pharmaceuticals.

Technical Parameters

Application
Suited for premium, high-value barrier applications:

• Sensitive Food Packaging (e.g., nuts, coffee, snacks)

• Pharmaceutical and Medical Device Packaging

• High-End Electronics Packaging

• Molded Fiber Caps and Closures

Customization
Achieve your exact barrier specifications. This line is highly customizable for R&D and high-spec production. We can tailor the vacuum fixturing for complex shapes, customize the number and type of drying zones, and integrate specific customized inspection systems to meet your quality standards.

Feature

• Validated Barrier Performance: Precision control over every parameter ensures consistent, certifiable results.

• Advanced Process Control (APC): Maintains coating weight and thickness within tight tolerances.

• 100% Product Fixturing: Vacuum chucks ensure zero movement during spinning for perfect edge-to-edge coverage.

• Data Integrity: Full traceability of process parameters for each production batch.

• Zero-Defect Mindset: Designed for integration with QA systems to eliminate coating defects.

Support and Services
Our partnership includes process validation support, on-site calibration services, and preventative maintenance contracts to ensure sustained peak performance and compliance.

Packing and shipping
All high-precision components are shipped in custom-designed, shock-absorbing packaging within sealed, moisture-proof wooden crates.

FAQ

• Q: Can this line handle new, bio-based high-barrier coatings?

  • A: Absolutely. The precision dispensing and customizable drying profile are ideal for challenging new materials. We can work with you to develop the optimal process.

• Q: How do you ensure coating uniformity on deep-draw products?

  • A: Through customized vacuum fixture design and programmable spin profiles that can be adjusted for different depths and angles within a single product.

• Q: Is the data logging system compliant with GMP?

  • A: Yes, the system can be customized to provide audit trails and electronic records that meet GMP requirements for traceability.
