Plano, TX — SunChips bags that are 100 percent compostable will rollout in the U.S. and Canada in the coming months, according to Frito-Lay North America, Inc.

The new SunChips packaging will comprise more than 90 percent renewable, plant-based material and, according to the company, will totally decompose in about 14 weeks.

In the U.S., prototype bags made from one-third plant-based material are widely available, and the company says it will launch the 90 percent plant-based bags on Earth Day, April 22, 2010.

Bags will be on shelves in Canada in March 2010 in eight-ounce and 15-ounce sizes, while the remaining line will transition in August of this year, the company says.

According to the company, the packaging has also been certified through the Biodegradable Products Institute’s internationally recognized labeling program.
