Technologies / Coating / Coil & Foil Aluminum Coating Lines

Customized Coil & Foil Aluminum Coating Lines

Because of its exceptional barrier properties, aluminum is used across a wide range of applications. From flexible and other packaging to protect foods, beverages, drugs and cosmetics to building / construction, isolation or heating/ air-conditioning.

We handle and process aluminum foil and perform coil coating for aluminum from very few microns (6 microns) to semi rigid aluminum (up to 500 microns). Besides coating, our lines can be equipped with other in-line processes such as embossing, printing, perforation, etc.

Coil & Foil Aluminum Coating Line Processes

At ILAMCO, we have developed important engineering & process know-how in aluminium foil and coil lacquering and coating and manufacture customized coating lines adapted to specific requirements.

Web Treatment

  • Embossing with customized patterns: Steel/Steel rollers – Steel/Paper or Rubber for foil aluminium applications
  • Vacuum rollers or belts
  • Primer on one or both sides of the web
  • Corona treatment:
  • Pre- treatment on coil coating: degreasing, cleaning and drying before primer application.
  • Specific tension control in multiple points of the web path (with tension handling elements such as dancer rolls or additional nips for tension isolation of line sections).


  • Single or turret with flying splice at max. production speed for foil aluminium.
  • Shaftless (mostly used) or shafted
  • Roll diameters up to 1600 mm
  • Roll weights up to 6000 kgs
  • Perfect winding accuracy according to material thickness / grammature.
  • Splicing systems:
    • Flying splicing systems for automatic turret unwinders and rewinders processing aluminium foil
    • Cutting and splicing: staple / strip join / welding (in coil coating).
  • High programmable tensions
  • Vertical under tension Accumulators for non-stop process in coil coating lines


  • Multiple coating materials depending on desired properties:
    • On foil aluminium: adhesives for lamination or other isolation or surface treatment
    • On coil aluminium: from primers or lacquers to polyesters, Silicone Modified Polyesters (SMP), Fluorocarbons (PVDF) and Plastisol (PVC),etc…
  • Coating widths of a few millimeters up to 2200mm
  • Coating weights of 0.5 g/m² to 100 g/m²
  • Coating media with a wide range of viscosities and different solvents: Water based / Solvent based / solid 100% (hotmelt)
  • Coating speeds of 0.1 m/min up to 400mts/min
  • Pre or self-metered coating methods
  • Coating systems:
    • Mayer bar
    • Roll over Roll
    • Rotogravure
    • Direct gravure
    • Offset roll
    • Curtain
    • Slot Die
    • Comma bar
    • … others variations


  • Dry laminating for foil aluminium and plastic film
  • Wet laminating for foil aluminium and paper
  • Special laminating materials for new fabrics or construction market (hotmelt, pvc…)
  • Single and multiple layer laminations for construction with special materials such as wood, rock wool, special fabrics, plastics (PVC…).

Drying & Curing

  • Flotation dryers (also called air suspension)
    • Non-contact and sinusoidal web guiding
    • Special nozzles design ensure efficient energy transfer from both sides
  • Roller dryer
    • Driven or not driven guide rollers
    • Laminar air flow
    • High speed air nozzles
    • Water or solvent based coatings
    • Independent and sectorized regulation for air speed, temperature and recirculation in each drying hood and section to optimize drying performance and energy consumption.
  • IR / UVI hood systems
