Fewer plastic layers, the same protection for your packaging.

Water-based barriers, primers and heat seals for paper, flexible packaging and digital printing. We help you choose the right family and trial it on your line before production.

  • Paper and board barriers for food and industrial packaging
  • Flexible packaging primers, barriers, and heat seals
  • Technical validation and application support before scale-up
From barrier target to commercial implementation

Results you can measure in your plant

Reference values from the Michelman technology we represent.

12622–272-min Cobb

Low Cobb, even diluted

HydraBan® keeps Cobb at 22–27 with 80% water in the mix.

100<0.8cc/m²/day

Oxygen out, without EVOH

Michem® Flex Barrier brings a PET film’s OTR below 0.8.

65 °Cseal initiation

Seals at low temperature

Water-based heat seals that start sealing from 65 °C on paper.

Manufacturer reference values (Michelman). Final performance is confirmed with a trial on your material and line.

I need guidance

A portfolio designed for technical decisions

Our product families are built to help packaging teams solve barrier, printability, food-contact, and converting challenges without adding unnecessary complexity to the line.

Circular packaging focus

Solutions built around recyclable, repulpable, and lower-plastic packaging routes.

Compliance-ready evaluation

Support for food-contact, performance, and validation requirements before you scale.

Barrier performance by objective

Water, grease, moisture, oxygen, and sealability options matched to the packaging need.

Application-oriented support

Recommendations shaped by substrate, coating method, converting line, and end use.

Choose faster and validate with less risk

Use the guide and Coaterex support to frame your barrier target, understand the required tests, and shortlist the right product family before running trials.

  1. Define the coating objective

    Start with the substrate, barrier target, print method, sealing needs, and end-market requirements.

  2. Review tests and application variables

    Align on COBB, Kit, MVTR, or other critical measurements together with the intended coating method.

  3. Move into validation

    Advance from the first shortlist to product specifications, trial setup, and production recommendations.

Support around the product decision

When your team needs more than a catalog, Coaterex can help accelerate testing, coating application, and technical validation.

Coating application support

We support pilot-scale application on reels and sheets so your team can validate primers, varnishes, and barriers before committing line time.

  • Application on paper, board, film, reels, and sheets
  • Validation of primers, varnishes, and barriers in production-like conditions
  • Technical basis to adjust parameters and define next steps

Technical validation

We help structure project validation, define application parameters, and interpret the results needed to move forward with confidence.

  • Definition of critical application parameters
  • Support during trials and interpretation of results
  • Recommendations to scale toward commercial validation or production
