WinCup Vio Biodegradable Straw-Slot Cup Lids - Convenient lids form the perfect complement to Vio™ foam cup selection, for easy sipping on the go. Vio™ lids have been shown to biodegrade 35% after 1087 days under conditions that simulate a wetter, biologically active landfill, using the ASTM D5511-11 test. Note that stated rate and extent of degradation do not mean the product will continue to decompose. Sturdy lids provide a tight seal—perfect for toting along your favorite coffee, tea or soda.
