On the eve of Earth Month, the SunChips brand officially introduces the world's first 100 percent compostable chip bag at an event in Los Angeles, along with details about a new national consumer education effort to encourage composting and greener lifestyles. The new 100 percent compostable bags are made with plant-based polylactic acid (PLA), a renewable material that also allows the bags to fully compost in approximately 14 weeks when placed in a hot, active compost bin. The new compostable bags, which stand as one of the latest sustainability initiatives from PepsiCo's Frito-Lay division, will be at full distribution in North America in time for the 40th anniversary of Earth Day on April 22.
