Stonyfield and clear lam broke significant barriers for a breakthrough use of pla polylactic acid in a highvolume dairy application. The new formfillseal multipack yogurt cups are made of 93 percent pla, a switch from polystyrene hips, believed to be the first for this market. The pla is made by natureworks and results in 48 percent lower greenhouse gas emissions vs. Hips. Compression strength increased by 1520 percent, resulting in fewer damaged products during transit. Stonyfield also overcame the difficult challenge of applying a good lidding seal to a pla cup, as the lidding film needs to withstand heat during application. In addition, using 93 percent plantbased material further drives their reputation as a leader in sustainability.
