Coatings for flexible packaging that is easier to recycle

Water-based Michelman primers, barriers and heat seals to simplify multilayer structures without losing protection or machine performance.

  • Mono-material structures
  • Food contact by grade
Flexible pouches and films with functional coatings

Fewer different materials, the same protection

Plastic is not the problem; material combinations that cannot be recycled are. Functional coatings move part of that function into thin layers on a simpler structure.

Mono-material structures

Single-material structures (PE, PP or paper) instead of multi-material laminates.

Thinner layers

Barrier and sealing from coatings a few microns thick, instead of extra films or layers.

Food contact

Grades with FDA documentation for direct or indirect contact, depending on product and use.

What changes in your structure

The same protection, with a material recyclers can actually recover.

Today

Multi-material laminate

  1. Printed PET film
  2. Lamination adhesive
  3. Aluminum or EVOH
  4. PE sealant film

Three materials that cannot be separated: not accepted in PE recycling.

With a water-based coating

Coated mono-material structure

  1. Printed MDO-PE film
  2. Michem® Flex oxygen barrier
  3. PE sealant film

All PE, with the barrier in a layer a few microns thick.

Results you can measure in your plant

Reference values from the Michelman technology we represent.

100<0.8cc/m²/day

Oxygen out, without EVOH

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

1.50.03cc/m²/day

High barrier on metallized film

On Met-PET, OTR drops from 1.5 to 0.03.

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.

Example structures

We define the structure first, then the coating.

This is what a package redesigned layer by layer can look like. These are illustrative examples; each case is validated on your line.

High-barrier paper bag

  1. Exterior: OPV Varnish (Thermal Protection + Gloss)
  2. Substrate: Kraft Paper
  3. Core: Oxygen Barrier Coating
  4. Interior: Heat Seal (Sealing + Grease Barrier)

Illustrative structure: validate barrier, sealing and recyclability.

Mono-material PE film

  1. Coating: Michem® Flex Oxygen Barrier
  2. Substrate: MDOPE (Oriented Polyethylene)

Illustrative structure: verify compatibility with the destination recycling stream.

How we work

Michelman technology, local support

We represent Michelman in the region and support trials at your plant.

Decisions based on data

Every recommendation is backed by OTR, MVTR and seal strength measurements.

Samples and pilot trials

Samples, pilot trials and formulation adjustments to reach production sooner.

Frequently asked questions

How do you get an oxygen barrier without EVOH or aluminum?

With a barrier coating such as Michem® Flex Barrier applied to the film or paper. On PET it brings OTR below 0.8 cc/m²/day, which makes mono-material structures possible.

What is a mono-material structure?

A package made from a single material family (all PE, all PP or paper) that can enter the matching recycling stream. The coatings add barrier and sealing in layers a few microns thick.

Do I need to change my equipment?

Usually not. The coatings run on flexo, gravure or coating stations already in the plant. We review your line before proposing a trial.

Let’s talk about your structure

Tell us the substrate, the function you need and your process. We will propose the coating and the trial.

Evaluate my application

Validate with a sample before you decide

Tell us about your application and an engineer will recommend the right coating for your substrate and your process.

  • An engineer replies within 24 business hours

  • Technical recommendation based on your substrate and line

  • Samples to validate on your own line, at no cost
