Alufoil’s total barrier to light, steam, aromas and liquids is a major reason for its use in the kitchen.The same properties can be used to stop evaporation and drying of paint, adhesives and fillers used in home decoration. Also it can deal with the highest temperatures encountered in cooking, whether in a convection oven or under the hottest grill. Another great advantage when used in the kitchen is the ‘deadfold’ characteristic of aluminium foil. Once folded around a joint of meat, or crimped onto the top of a casserole or storage pot, the alufoil stays folded and does not spring back.
