Co-founders of the GreenBox—a patented pizza box that separates into four plates and yet can still store any leftovers—will appear on ABC’s “Shark Tank” Jan. 30, at 9 p.m. eastern time.

This is the second unique packaging idea this week that Packaging Digest has reported will be featured on the popular show. Inventors of the patented The Friend End lip balm container will pitch their products and packaging on “Shark Tank” next Tues., Feb. 3 at 8 p.m. ET.

But tonight, GreenBox principals Jennifer Wright-Laracy and Ned Kensing will go tooth to tooth with the show’s ferocious investors to convince them that eco-conscious alternatives to traditional food packaging not only have merit for the planet, but they have profit potential.

President Wright-Laracy calls their “Shark Tank” experience a once-in-a-lifetime opportunity: “With our GreenBox design, our goal is to make the world a greener place—one pizza box at a time. National exposure on a hit show like ABC’s 'Shark Tank' will help us make this dream a reality—and to share our vision for a greener tomorrow.”
