Frequently Asked Questions

EarthCoating® is a suite of mineralized resin formulations that combine calcium carbonate (chalk) with polymer resins. The high mineral content — over 51% — means that during the paper recycling process, the coating behaves like clay rather than plastic, fracturing into small, dense particles that are easily separated from paper fibers.

HyperBarrier is a mineral-polymer nanocomposite technology available as both a coating (for paper substrates) and a film (for flexible packaging). It delivers up to 200x improvement in oxygen barrier and 7x improvement in moisture barrier compared to conventional polyethylene, while remaining recyclable.

Yes. EarthCoating is designed to fracture into small, dense particles in the pulping process, allowing it to be recycled in the standard paper recycling stream. Paper cups with EarthCoating qualify for Path 13, the premium uncoated paper recycling stream, and have received a 95% recyclability rating from Der Grüne Punkt (The Green Dot).

Yes. HyperBarrier Film is a monomaterial polyethylene film, making it fully compatible with existing PE recycling infrastructure (#2 or #4 recycling streams).

No. EarthCoating is a drop-in solution that runs on standard extrusion coating equipment. No capital expenditure or changes to existing manufacturing processes are required.

EarthCoating EC-40 costs 15-25% less than bio-resin alternatives and is cost-competitive with conventional neat polyolefin pricing. The mineral content replaces expensive polymer, reducing overall material costs.

Yes. EarthCoating is compliant with 21 CFR food and drugs, US FDA, and is suitable for contact with all food types under Conditions of use B-H of 21 CFR 176.170(c) Table 2. It also complies with EU food contact regulations.

EarthCoating is used across a wide range of paper-based packaging applications including hot and cold cups, food trays, folding cartons, flexible pouches, sachets, labels, and corrugated packaging.

HyperBarrier Coating is an extrusion coating applied to paper substrates, creating recyclable paper-based packaging with high barrier performance. HyperBarrier Film is a standalone monomaterial PE film that replaces complex multi-layer plastic structures while remaining recyclable in the PE stream.
