Barrier Coatings for Fiber-Based Food Packaging
Food-contact-compliant barrier coatings protect against grease, oil, and moisture while keeping paper packaging recyclable and repulpable.
Solutions for paper-based food packaging
Brand owners and converters face a difficult trade-off: package food safely, meet tightening recyclability regulations, and avoid expensive equipment changes. Dow's RHOBARR™ Barrier Coatings answer all three.
RHOBARR™ Barrier Coatings guard against grease, oil, and hot or cold liquids, so the package performs through filling, shipping, and shelf life. They also deliver heat sealability for clean, reliable seals on cups, pouches, and cartons.
Sustainability is built in. Repulping studies show that select RHOBARR™ grades let mills recover and recycle more than 99% of paper fibers.
Dow’s RHOBARR™ Barrier Coatings for pet food
When buying pet food, the length of time that food stays fresh is as important to consumers as the quality of the ingredients. Pet foods often have a high fat content, meaning that there is a risk of oil and grease bleeding through the packaging. Dow’s RHOBARR™ Barrier Coatings are more than up for the challenge of protecting pet food from such scenarios, as it has been specifically designed to sustainably coat paper packaging requiring multifunctional oil and grease barriers.
RHOBARR™ Barrier Coatings for stand-up pouches
Flexible, stand-up packaging pouches are convenient, self-standing, and often resealable, a perfect fit to meet consumers’ needs. RHOBARR™ Barrier Coatings allow effective protection of products using stand up pouch packaging, while also providing enhanced recyclability and repulpability.
RHOBARR™ Barrier Coatings for boxed dry goods
In some areas, ink on food boxes contains mineral oils that are not safe for consumption, can leech onto the product without a protective barrier coating. Protecting food products from potential mineral oil migration is a critical packaging challenge. RHOBARR™ 214 Emulsion delivers proven oil and grease barrier performance, preventing saturation of the paperboard substrate and helping maintain package integrity and product safety.

Paper-based barrier coatings for food packaging - products
Beyond barrier performance, the right binders and auxiliaries fine-tune coat weight and gloss. Our binders and supporting additives pair with RHOBARR™ Barrier Coatings to balance barrier properties, surface finish, and converting efficiency, so formulators can hit target specs without compromise.
Film formers establish the continuous, defect-free layer that makes a barrier coating work. Dow's resins, binders, and film formers help create durable, flexible films with strong adhesion to paper and board, supporting grease, oil, and moisture resistance across food packaging formats.

Food packaging container coatings FAQs
Common options include water-based dispersion and emulsion coatings (acrylic, styrene-acrylic, polyolefin), extrusion coatings like polyethylene, and traditional wax. RHOBARR™ Technology falls in the water-based category, built for oil, grease, and liquid barrier with recyclability in mind.
Confirm it meets FDA 21 CFR 176.170 for your food types, temperatures, and contact times. Then validate real performance: oil and grease resistance, water resistance, and moisture control. Prioritize recyclable coatings that run on existing equipment.
