Metacoat®
In-Chamber Coating and Metallizing

  • Lower Capital and Operating Costs
  • Excellent, predictable barrier properties
  • Possibilities for new laminated and unlaminated structures
  • Environmentally reduces: Materials, energy use and Carbon footprint

Metacoat® is the first technology in the world that enables flexo printing of EB curable coatings at production speeds in the high vacuum environment of a metallizing chamber. This technology, covered by several patents, allows for streamlined operations, with the ability to both metallize and coat in a single pass. Also, by protecting the metal layer immediately after the deposition zone, significant barrier improvements can be achieved on a wide variety of substrates.

Inline Coating and Metallizing Process


Lower Capital and Operating Costs

The Economics of One Step vs. Two Step Coating and Metallizing

2 Step Process


Capital Investment:

Two units and two production areas
= Higher fixed costs

Operating Costs:

Requires two sets of operators
Yield losses > 10%
= Higher operating costs

1 Step Metacoat® Process


Capital Investment:

One unit and one production area
= Lower fixed costs

Operating Costs:

Requires one set of operators
Yield losses ~ 5%,
= Lower operating costs


Improved Barrier Properties

The Metacoat® process seals and protects the metallized layer inside the chamber, significantly improving and stabilizing barrier properties.

The causes of defects:

  • Scratches
  • Impurities flaking off

The in-chamber coating protects the metal layer and impurities are trapped.

When comparing coated and uncoated metallized samples under a strong backlight: The uncoated samples have higher levels of pinholes than the coated ones.

WVTR vs. Optical Density

Significantly improve barrier properties of a film without having to work at optical densities greater than 2.0 – 2.2

Reduced Environmental Impact

Reduction of Materials, energy use and Carbon footprint

Converting Operations


Layer Elimination

Potential layer elimination for 2 different structures:

  • Dry powder pouch : Aluminum foil
  • Bag-in-box pouch: Metallized OPP

It also allows us to look at eliminating additional plies of material, that are there primarily to protect the metallized layer

Improve Barrier Properties and Significantly Reduce Your Carbon Footprint with In-Line Metallizing and Top-Coating

The traditional method of preparing a top-coated metallized film using roll-to- roll processes is to carry out two separate, independent steps. This two-step process creates certain inherent disadvantages, such as high operating and capital costs
