Packaging for a more sustainable world

Eastman Solus™ for paper coatings

Single-use food packaging faces increased scrutiny as regulators and global brands seek to move toward a more sustainable mindset. Many common packaging materials, including paper items like beverage cups and takeout boxes, are often rejected by recycling and composting facilities. Solus™ performance additives can change that.

A better 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. It also facilitates reduction in coat weight and lowers scrap rate compared to incumbent biopolymers alone while leveraging existing assets.

Beyond these performance advantages, Solus™ enhances sustainability from the start 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. Paper coatings made with Solus™ are certified biodegradable and compostable,2 helping keep materials out of landfills.

Increase productivity

Our Solus™ solution offers 10%–15% higher output compared to PLA (per 1,000 cups).

A paper cup decomposes into compost in four stages — intact, partially broken down, fragmented and fully composted.

Leave nothing behind

Articles made with Solus™ biodegrade in months, while LDPE can take decades.
