International Paper, Smart Planet Technologies explore sustainable packaging options

Global paper and packaging company International Paper, Memphis, Tenn., has completed a license agreement with Smart Planet Technologies™ to explore the development of products using EarthCoating™, a mineralized barrier coating for paperboard products.

The company’s coated paperboard division plans to create a line of folding carton and cupstock products within its Everest® and Fortress® grade lines that would improve yield and reduce plastic use while offering the same barrier properties available today. Trial work and pilot testing are scheduled for the first quarter of 2013.

The mineralized resins contain less plastic than traditional low-density polyethylene coatings. They are heat-sealable and FDA-compliant for direct food contact.
