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 for recyclability 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 special handling.

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.

EarthCoating may be used to create a variety of paper packaging materials. For further information, click each of the logos below:

calcium-carbonate-polyethelene

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:

  • Repulpability

    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.

Smart Planet Technologies offers a variety of custom mineralized blends designed to meet specific criteria such as compostability. To learn more about our compostable barrier coating options, contact Todd Gasparik at 949-610-7063 or Todd@SmartPlanetTech.com
Smart Planet Technologies offers a specific mineralized polypropylene blend designed to handle microwave conditions.
Yes, when compared to 100% LDPE, EarthCoating provides enhanced heat seal capabilities which may be run at standard high line speeds. (3rd party heat seal testing results are available upon request)
When compared to 100% LDPE, EarthCoating provides superior moisture, oil, grease and fatty acid barrier performance. (3rd party barrier testing results are available upon request – i.e. MVTR, Cobb, Canola Oil, 3M Kit Test etc.)
When compared to traditional plastic coatings such as polyethylene, polypropylene, PLA or bio-derived extrusion coatings, EarthCoating may provide immediate material cost savings. In addition, EarthCoating often delivers superior performance benefits resulting in potential source reduction which may lead to further economic savings. Also, unlike traditional polyethylene-coated paperboards, post-industrial EarthCoating trimmings may be sold at a premium to recyclers. For additional questions, please contact Todd Gasparik at 949-610-7063 or Todd@SmartPlanetTech.com
While some vendors may simply not be aware of EarthCoating, we’ve successfully commercialized millions of packages using EarthCoating technology and are happy to bring them up to speed on all of the benefits. To read about some of the products that make use of EarthCoating including Whole Foods trays, High Liner Seafood folding cartons and others, visit our Press web page.

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.
