Kuraray America, Inc. (Kuraray America), a world leader in performance-based polymers and special materials technology, recently announced a new grade of PLANTIC™, the company’s sustainable, high-performance barrier material.
A plant-based resin designed specifically for converters who perform extrusion coating, PLANTIC™ EP can be used to develop sustainable gas and aroma-barrier solutions with paper, paperboard, or traditional film substrates.
The new resin grade recently passed repulping and recyclability certification from Western Michigan University (WMU), laying the groundwork for sustainable barrier pouch and carton formats for brand owners and converters. With PLANTIC EP, the market now has a high-barrier option that can be fully recoverable and recyclable in the U.S. paper stream.
“Companies recognize the need for packaging to assure product integrity and shelf life, while consumers don’t want to buy products which add to landfills,” said Tom Black with Kuraray’s Plantic division. “We noticed a gap in the market and need for a sustainable material that could be used to produce high-barrier pouches and cartons and knew PLANTIC EP could be a game-changer. The new resin grade not only complements our customers’ and retailers’ dynamic range of products, but with recyclable certification from Western Michigan University, it helps brands achieve their sustainability objectives, enabling us all to leave behind a better world for our children.”
Derived from starch, PLANTIC is the world’s most advanced bio-based plastic. It can be used in both recycle-ready and compostable formats while providing renewable, plant-based content and excellent gas-barrier performance to extend shelf life. It can dramatically reduce the environmental impacts produced by traditional packaging materials while providing the opportunity for materials once considered not recyclable to be reusable.
In designing a high-barrier pouch for recyclability, Kuraray extrusion coated PLANTIC EP to kraft paper and capped it with a tie/heat seal layer with resin from Westlake Polyethylene. When used within a multilayer film, PLANTIC EP helps create a high-barrier, flexible pouch or carton, allowing other layers in the structure to be separated, recovered, and potentially recycled or composted.
“Our collaboration with Kuraray utilized our application development resources to the fullest to create a truly unique offering in the market,” said Amy Moore, vice president, Westlake Polyethylene. “We understand Kuraray’s technology and look forward to working together on further developments as they commercialize the offering across the bandwidth of market segments and categories.”
