Extrusion Coatings & Moisture on Paper / Foil

Why Control Moisture During Production?

The latest technology for extrusion coatings on paper/foil allows for the application of these coatings to modern materials never before coated, such as packaged materials that contain acids, oils, fats, or fragrances. To ensure that these coatings perform well, the extrusion coatings on paper/foil moisture must be precisely controlled at all points of production. MoistTech is the #1 choice for the job!

By controlling moisture in extrusion coatings on paper/foil, not only do manufacturers better protect packaged contents, for example but also reap many production benefits, including:

    • Flat coat weight profiles
    • Optimized coat weight
    • Improved materials usage
    • Improved process efficiency
    • Reduced scrap

Optimize Production: Instant ROI

State-of-the-Art Technology

Inadequate measurements of moisture levels in paper, film, and foil products can have a direct impact on the dimensional properties of your web or sheet, as well as the overall quality of the final product. This can lead to variations in mechanical properties and how the material responds to stress, resulting in issues such as unevenness, stretching, shrinking, bagginess, and length discrepancies. The manufacturing processes involved are often intricate, necessitating specialized measurements and expertise in web gauging applications. The coating combination is typically the most valuable component of converted paper, film, and foil products, making it crucial to employ the right coat weight measurement technique.

MoistTech offers a range of non-contact gauges specifically designed for coat weight measurement in web gauging applications, along with extensive application knowledge. Their expertise covers a wide array of coating techniques, ensuring the most effective moisture measurement system in the industry. These solutions deliver precise coat weight measurements and controls that are not influenced by the characteristics of the substrates. With these tools, line personnel can effectively monitor the coating process and achieve consistent, long-term results.


Our equipment never comes into contact with the product, allowing for less waste

zero drift

Our sensors are guaranteed not to drift over time – which saves time and money

closed loop

Create a closed-loop process by tying a moisture sensor into your PLC. Full control over the line!
