If You Care Aluminium Foil is made with 100% recycled aluminium. While traditional foil manufacturing is a power-intensive process, recycled foil uses 95% less energy to produce. Because there is no need to mine, this production creates less waste, while reusing a precious resource. It protects food against light, oxygen, humidity and bacteria. It is not recommended for use with acidic or fatty foods. It can be recycled again, provided that your local recycling centre accepts it.
