We've changed the game.

Unlike traditional plastic-coated paper cups and other paperboard barrier packaging which ends up in our landfills due to the difficulties recyclers have processing these materials through their equipment, packaging made with EarthCoating® uses 51% less plastic and is engineered to be easily pulped into recycled paper using conventional paper recycling equipment. To learn about reCUP® specifically, visit


Did you know?

Paper cups, food trays, folding cartons, take-out boxes, ice cream containers, food wraps and lots of other plastic-coated paperboard packaging materials are sent to the landfill.

The first step to getting paper cups and other paperboard barrier packaging recycled is to make them valuable and easy for recyclers to process through their conventional paper recycling equipment. 



INNOVATIVE mineralized-resin offering significant environmental, performance & economic benefits compared to traditional plastic coatings. 

EarthCoating® addresses three important pillars of sustainable packaging:



EarthCoating® may be used to create paperboard barrier packaging that can be easily pulped into recycled paper 



EarthCoating® provides superior barrier, heat seal and printing performance compared to traditional plastic coatings



EarthCoating® offers significant economic savings compared to PLA and other bio-resin based alternatives

An overview of the Repulpability and Recyclability of paperboards with EarthCoating®

The graphic to the left illustrates the process of paper recycling. A major part of the process includes extracting and cleaning fibers from non-paper contaminants that can found in the recycled paper stream. Unlike traditional plastic coatings, EarthCoating® is engineered for efficient processing in recycling systems. EarthCoating® is designed to fracture into small, dense particles in the pulping process, thereby avoiding the challenges found with traditional plastic coatings.

We’ve recently added additional content to our repulpability report and will continue to update our data as new information becomes available.
