Smart Planet Technologies launches coating for paper-based flexible packaging

Mar 23, 2025

Smart Planet Technologies has launched HyperBarrier, a ternary nanocomposite coating designed for paper-based flexible packaging.

The technology company said the innovation offers ‘up to twenty-fold’ improvement in oxygen barrier performance and significant enhancement in moisture barrier compared to traditional polyethylene coatings.

This, it said, opens new doors for brands to switch to paper from plastic packaging, where previous barrier options fell short.

Will Lorenzi, president, Smart Planet Technologies, said transitioning from plastic to paper-based packaging has presented significant hurdles:

He said HyperBarrier directly address these issues:

Chris Tilton, co-founder and inventor at Smart Planet Technologies, said: “While the industry has focused on developing new plastics for sustainability, our approach with mineralized coatings has shown superior results in enhancing packaging performance, reducing plastic use, and ensuring recyclability.”
