If You Care's aluminum foil is made with 100% recycled aluminum, using 95% less energy to produce than more conventional aluminum. Foil protects food against light, oxygen, humidity and bacteria, and helps cover turkeys, roasts, and veggies during roasting or grilling to keep them from burning. It's not recommended for use with acidic or very fatty foods. Heavy Duty Aluminum Foil is thicker, stronger and wider than the regular If You Care foil. 30 square feet of sturdy recycled foil (23 ft x 15.75 in). A great pantry staple!
