The packaging industry faces increasing pressure to adopt more circular designs that address tightening packaging regulations, without compromising on performance. The latest edition of the Spotlight sees Dow explain how its liquid RHOBARR™ Barrier Coatings offer excellent barrier properties while meeting challenging recycling thresholds.
RHOBARR™ Barrier Technology can be applied by widely used paper coating equipment, making them attractive to mills, converters and brand owners who seek to transition to more sustainable packaging.
RHOBARR™ Barrier Technology offers solutions tailored to a variety of needs, whether you’re seeking enhanced recyclability for fibre-based on-shelf packaging, ultra-thin coatings for quick-serve food applications, or easy-to-recycle options for non-food consumer goods.
Explore how these innovative coatings support different packaging types, combining sustainability with the protection and appeal that brands and consumers expect. RHOBARR™ Barrier Coatings at Dow.com.
Multi-functional coatings for on-shelf paper food packaging
RHOBARR™ Barrier Coatings enable various types of fibre-based retail and on-shelf packaging. For these packaging types, RHOBARR™ Technology offers features such as heat sealability in combination with a good barrier against oil & grease, water and vapour, oxygen and mineral oil. Such combinations of RHOBARR™ Barrier Coating functionalities still allow high recycling yields, provided these coatings are applied properly.
Coating solutions for foodservice packaging
RHOBARR™ Technology offers cost-efficient yet tailored barrier performance while promoting highly recyclable food-service packaging, which appeals to sustainability-oriented consumers.
Dow offers barrier coatings to withstand a wide variety of foodstuffs offered in the quick serve food industry, including:
- Frozen, chilled and hot substances
- A broad range of greases and oils
- Mineral oils
Paper coating options for non-food consumer goods
RHOBARR™ Barrier Coatings allow consumer products to be packaged in a sustainable and appealing way, without sacrificing product protection and packaging performance. These coatings help protect consumer products during transportation, storage and delivery, while preserving the inherent recyclability and natural appeal of paper.
Key benefits of RHOBARR™ Barrier Technologies
RHOBARR™ Barrier Technologies offer a range of benefits that are highly relevant for various types of fibre-based packaging:
- Highly circular packaging: packaging with RHOBARR™ Barrier Coatings successfully passed repulping tests of multiple renowned institutes. RHOBARR™ Technology therefore enables highly recyclable and well-performing fibre-based packaging. Its coat weight reduction potential can help to meet requirements under the PPWR regulation.
- Coating versatility: RHOBARR™ Technology provides barrier- and heat-sealing functionality. Different RHOBARR™ Barrier Coating products can be combined to produce packaging that offers multi-functional performance. This versatility makes them a great choice to produce a wide variety of packaging types.
- Compatibility with existing equipment: RHOBARR™ Barrier Coatings can be successfully applied on 2D and 3D substrates, using conventional liquid coating methods, eliminating the need for significant investment.
- Lower environmental impact: the reduction in coat weight and efficient production processes can contribute to a reduced environmental footprint of barrier coatings.
- Availability: with an investment made to expand production capacity at Dow’s flagship coatings plant in Lauterbourg, France, Dow is well-positioned to address the growing demand for sustainable packaging solutions.
RHOBARR™ Barrier Coatings offers future-oriented producers a step forward in creating more sustainable fibre-based packaging. Learn more at Dow.com.
