Paper and board

Keep grease off your paper packaging

We offer coatings for boxes, trays, and wraps that need to resist oils and grease without relying on traditional plastic lamination.

  • Grease and oil control
  • Cleaner packaging presentation
  • Scalable to water barrier, heat seal, and release
Keep grease off your paper packaging

What your packaging can achieve

If grease is hurting presentation, stiffness, or recyclability today, this solution helps improve those areas without making converting more complex.

Protect the product and the brand better

Avoid stains, halos and grease migration: the first thing consumers see when they open the package.

Move closer to sustainability targets

Lets you explore alternatives to PE laminations and PFAS-based chemistries in food-contact packaging.

Scale without starting over

You can begin with grease resistance and add water barrier, heat seal, or release as the application demands.

What changes in your structure

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

Scale the solution to your application

Not every package needs the same performance level. That is why the barrier can evolve in stages without replacing your entire platform.

What we review with you

We define the right combination based on the food, substrate, and production process.

  • How much grease, oil, or moisture the package must resist
  • Your current substrate: kraft, folding carton, or corrugated
  • Whether you also need water barrier, heat sealing, or release

One platform that grows with your package

Start with grease resistance and add functions when needed

This helps you launch faster, avoid unnecessary supplier changes, and match the solution to the real use case of the pack.

  1. Grease barrierFor boxes, trays, and wraps that must resist oils and grease at a high level.
  2. Grease + waterAdds resistance against moisture or condensation when the application requires it.
  3. Grease + water + heat sealAdds sealing capability for formats that need closure or extra protection.
  4. Grease + water + heat seal + releaseAdds non-stick properties for baked goods, paper plates, and other specialty applications.

How it works in practice

A technical view of the attributes that support performance in food packaging applications.

Technical basis of performance

Our water-based coatings create a functional barrier on paper or board that helps control grease and oil migration while preserving pack performance in food-contact applications.

  • Improves substrate resistance to grease and oils
  • Helps preserve pack appearance, stiffness, and functionality
  • Supports structures more aligned with recyclability goals

Validated grease resistance

Select testing for the coating and food. A Kit value alone does not confirm end-use performance.

Repulpable

It is designed to fit paper recycling processes better than a typical plastic-laminated structure.

PFAS-free

Helps reduce formulation and regulatory concerns in food-contact packaging.

Versatile in converting

Works on folding cartons, corrugated board, and kraft, and can adapt to the barrier level each pack needs.

Where it creates the most value

Especially useful when the food releases grease, oil, or light condensation and the pack still needs to look good.

Fast food

Fast food

Boxes and wraps that need to handle grease during eating, transport, and delivery.

Bakery and pastry

Bakery and pastry

Bases, trays, and boxes for products with butter, fillings, or glazes.

Pizza boxes

Pizza boxes

Reduces stains on the base and helps the board keep its stiffness.

Snacks and frozen foods

Snacks and frozen foods

Can combine grease barrier with other functions for more demanding applications.

Key questions

What does Kit 12 mean?

It is the upper level of the TAPPI T 559 repellency scale. Applicability to film barriers and non-fluorochemical treatments must be validated; supplement with actual food and packaging tests.

Does this replace plastic lamination in every case?

Not always. It depends on the food type, contact time, moisture, sealing needs, and substrate. That is why we review each application before recommending the structure.

Does it contain PFAS?

No. The solution is formulated PFAS-free, which helps address both regulatory and market requirements in food packaging.

How do I know which barrier combination I need?

We review the product, substrate, converting process, and expected performance with you. From there we define whether a grease barrier is enough or whether it should also include water, sealing, or release.
