Steaplus® Prime Environment friendly minerals for barrier coatings

Working closely with leading brand owners and packaging converters, Imerys has developed Steaplus® Prime, a natural mineral base for water-based barrier coatings for the food and non-food segments of the fiber-based packaging industry. Easily recyclable, Steaplus® Prime based coatings provide an environment-friendly alternative to wax, fluorochemical and petrochemical based polymer coatings.

Steaplus® Prime is ideal for:

  • Moisture vapor barrier coatings
  • Oil and grease barrier coatings
  • Water barrier coatings
  • Mineral oil barrier coatings

It is:

  • Printable
  • Repulpable
  • Recyclable
  • FDA & BfR compliant for direct food contact

We can also fine-tune our coatings grades to match your specific requirements by finding the optimum combination you need in terms of:

  • Oleophobicity
  • Hydrophobicity
  • Moisture vapor resistance
  • Printability
  • Stiffness
  • Opacity
  • Machine runnability
  • And cost-effectiveness

Steaplus® Prime based coatings can be applied using online or offline dispersion coating techniques, or on a printing press. 

They are adapted for varied grades of fiber-based substrates - carton, corrugated or flexible paper.

They are currently being used in multiple packaging segments, including fast food, bakery, confectionary, cosmetics, medicines, electronics and paper sacks.

We offer a full range of bespoke formulation and technical and process support services to help you match the right mineral grade to your application requirement.
