Next-Gen 1650mm Double Head Gravure Coating Technology
At Everest Holovisions Limited, our high-speed converting infrastructure is anchored by our advanced 1650mm Double Head Gravure Coating Machine. This state-of-the-art machinery line combines high-precision coating, uniform adhesive deposition, and high-speed lamination capabilities. Engineered for maximum operational efficiency, it allows us to handle extra-wide webs up to 1650mm while maintaining flawless web tension and micro-level coating accuracy for flexible packaging, security holographic products, and premium labels.
In-line Corona Pre-Treatment System
To guarantee ultimate liquid adhesion and flawless surface preparation, the machine features an in-line Corona treatment station.
Instant Surface Activation
Increases the surface energy of films just milliseconds before the coating heads.
Flawless Wetting
Ensures uniform chemical and lacquer distribution across the entire 1650mm web width.
Eliminates Delamination
Provides maximum bond strength between the substrate and applied coatings.
High-Precision Servo Registration System
Achieving pixel-perfect accuracy at high speeds requires absolute mechanical control.
Independent Servo Controls
High-torque servo motors independently manage each gravure coating head and tension zone.
Micro-Level Register Accuracy
Automatically detects and corrects print or coating registration deviations in real time.
Reduced Scrap Rate
Minimizes material trim waste during machine acceleration, deceleration, and roll changeovers.
Mayer Bar (Metering Rod) Coating Head
For applications requiring high-viscosity coatings, dense barrier chemicals, or heavy adhesive weights, the system utilizes an interchangeable Mayer Bar assembly.
Thick Coating Management
Smoothly meters down thick varnishes, release agents, or barrier chemicals that conventional gravure cells cannot handle.
Flawless Coating Uniformity
Eradicates lines, streaks, and uneven spots, guaranteeing a completely smooth, blemish-free finish.
Turning Bar (Turn-Bar) for Single-Pass Double-Sided Coating
Maximizes productivity and eliminates the need for secondary machine passes.
Dual-Sided Processing
The specialized turn-bar system safely flips the substrate web mid-process.
Single-Pass Efficiency
Applies coatings, functional lacquers, or security elements to both sides of the material in a single production run.
Thermal Savings
Reduces heat exposure on the film by utilizing a single pass through the drying tunnels, preserving substrate tensile integrity.
Wide-Format 1650mm Lamination Capability
Beyond precision coating, the machine operates as a heavy-duty, wide-format laminator.
Multi-Layer Structure Assembly
Bonds distinct metallized films, holographic films, PVC, or papers seamlessly.
High-Speed Roll-to-Roll Yield
The generous 1650mm wide format matches our vacuum metallizing output, allowing converters to run high-up configurations to dramatically increase output speeds and minimize waste.
Versatile Material and Substrate Matrix
The system effortlessly processes a broad selection of standard converting materials matching our metallizer specifications (from 6 microns to 50 microns).
BOPET & BOPP Films
Ideal for high-barrier food packaging and holographic labels.
PVC & CPP Substrates
Perfect for twist-grade confectionery, blister backings, and heat-sealable bags.
Speciality Papers & Boards
Tailored for premium folding cartons, liquor boxes and premium labels for pharma, FMCG, automotives and beverages.
