Eastman Solus for paper coatings

Single-use food packaging faces increased scrutiny as both regulators and global brands seek to move toward a more sustainable mindset. Many common packaging materials are not accepted into recycling streams and composting facilities. Even paper packaging, such as beverage cups and takeout boxes, is not always accepted for recycling or composting. Consumers are hungry for a change.

Solus performance additives can enable ease of processing for bioplastics on paper and board while maintaining or enhancing end-of-life claims and performance attributes for food-service products.

A sustainable option

There is a growing focus on biopolymers and circular options for food packaging. Unfortunately, many biopolymers are challenging to process, require capital investment to existing lines and have inferior end-use performance. Solus can alleviate these concerns by improving paper adhesion, enabling faster coating speeds, facilitating reduction in coat weight and lowering scrap rate compared to incumbent biopolymers alone while leveraging existing assets.

In addition to these performance benefits, Solus enhances sustainability at the beginning of life with its biobased content and recycled content1 via Eastman’s carbon renewal technology. The use of biobased content enables recyclability of the product at the end of life. This helped Solus earn certification from Western Michigan University for recycling and repulping.

Paper coatings made with Solus are also certified biodegradable and compostable,2 helping keep materials out of landfills. This meets customer standards for sustainability and increasingly stringent regulations around circularity without compromising performance.

Improving processability and coating performance

Solus provides several advantages to coaters, converters and brand owners.

The Eastman Solus 7000 series can improve processability of biobased polymers, enhance end performance and enable sustainable end of life through the recycling or composting of paper-based packaging.

Benefits to coaters

  • Enhances adhesion to paper
  • Reduces coat weight (up to 50% downgauging)
  • Increases line speed for extrusion coaters
  • Reduces scrap rate
  • Reduces overall cost
