Biodegradable Frito-Lay bags getting yanked from shelvesBiodegradable Frito-Lay bags getting yanked from shelves

The snack food giant is pulling most of the polylactic acid (PLA)-packed Sun Chips out of stores because consumers have complained that the material is too loud. As my colleague Tony Deligo reported here, the package used is a six-layer, 20-µm-thick film (PLA-print-adhesive-metal layer-PLA-PLA sealant) that's 90% by weight PLA and fully compostable in approximately 14 weeks when placed in a hot, active compost bin.
