EarthCoating is a highly mineralized resin alternative to 100% plastic coatings for paper based packaging that’s engineered for recyclability and provides superior barrier, heat seal and print performance.
Ideal for all types of paperboard barrier & high-quality print packaging applications, EarthCoating delivers premium aesthetics, functionality and barrier performance. Paperboards with EarthCoating are also engineered to be easily processed through paper recycling equipment and often qualify as “Widely Recycled” under the How2Recycle* program.
Using up to 60% less plastic, paper packaging with EarthCoating may be repulped through existing paper recycling equipment without any modification or additional infrastructure.
Available in clear or white formulations using various mineralized resin blends, EarthCoating may be customized to meet your specific aesthetic, functional, barrier and environmental needs.

EarthBoard is a premium, bright, white paperboard barrier material that’s engineered for recyclability.
Calcium Carbonate is blended into polyolefin resin, creating a compound called EarthCoating®, which may be extrusion coated onto various papers and paperboards at high commercial line speeds using existing machinery and without any additional capital investment.
Blending low cost minerals into polyolefin resin yields the following benefits:
Traditionally, mixed grade paper barrier packaging applications such as paper cups, plates, etc. are coated with 100% polyethylene and other similar materials, which make the resulting products poor candidates for repulping because of the difficulty recyclers have separating the plastic coating from the paperboard.
By contrast, mixed grade paper barrier packaging applications with EarthCoating® provide a great potential for post-consumer repulpability because they can be processed through the paper recycling stream as if there were no coating on them at all. Paperboards with EarthCoating® offer a repulpable alternative for any polyethylene-coated paper packaging materials. EarthCoating® fragments into small dense particles that are easily removed as part of the recycling process.

Reduction of Plastic
The mineral content in EarthCoating® displaces up to 60% of the plastic by weight that would otherwise be found in a polyolefin coating.
Energy Use Savings
Energy savings are realized whenever paperboards are recycled. Paper tonnage which might otherwise be buried in US landfills may be collected and reused, resulting in reduced greenhouse gas emissions and energy savings.
For example, if the approximately 58 billion paper cups that are buried in US landfills each year were to be recycled, approximately 700,000 tons of paper would be recovered – resulting in energy savings equivalent to removing almost a quarter million cars from our roads.
Source Reduction Enabled by Superior Performance
When switching from traditional plastic coating to EarthCoating®, source reduction may be achieved via lower coat weights, leveraging the superior barrier performance of a mineralized resin coating.
Superior Moisture Barrier
The minerals in EarthCoating® produce a tortuous path for moisture to pass through, resulting in better moisture vapor transmission rates (MVTR).
Superior Heat Seal Performance
Mineralized resins absorb and dispel heat differently than neat polyolefins, resulting in better heat seal performance.
High Quality Print Surface
Unlike traditional polyethylene, EarthCoating® offers a high surface energy complete with a typical post-corona dyne level of 46, providing an excellent print surface for high quality graphics.
Enhanced Adhesion Surface
The high surface energy of EarthCoating® provides enhanced adhesion capabilities.
Post-Industrial Trimmings Rebate
Paper and paperboard packaging applications coated with EarthCoating® are engineered for repulping through existing paper recycling streams, providing premium high value fibers without plastic contamination nor a laborious depolymerization process found in the effort to process traditional paperboards with 100% polyolefin coatings. As a result, industrial EarthCoating trimmings are sought after at a premium value by recyclers, resulting in a potential rebate for supply chain vendors.
Material Cost Savings
The use of low cost minerals in the resin blend, offsetting traditional 100% resin blends, provides a material cost savings.
Source Reduction Enabled by Superior Performance Yields Cost Savings
Compared to traditional plastic coatings, EarthCoating® provides superior barrier performance, which often results in an opportunity to down gauge coat weights, leading to source reduction and potential cost savings.

All environmental claims in the US are subject to FTC Green Guides. Prior to making any environmental claims on your package, we encourage to you to contact Smart Planet Technologies.

Also, despite all of the environmental, performance and economic benefits, innovative technology such as EarthCoating is often referred to as disruptive and may be seen as an opportunity or threat depending on who you are talking to. For example, if your incumbent supplier is currently selling you packaging made of polyethylene-coated paperboard, they may want to keep things as they are for fear that if they introduce something new, they may be increasing their risk of losing your business. At the same time, new vendors trying to earn your business may see EarthCoating as an opportunity and use it as a way to generate your interest. Either way, EarthCoating is worthy of serious consideration in support of your sustainable packaging and cost saving initiatives.
