Abstract
Abstract A place mat is disclosed which comprises a paper sheet and a composition coating comprising a blend of water, a water soluable salt, a wax and a polymeric material which both coats and impregnates the paper sheet, whereby said sheet is rendered substantially hydrophobic and it and items placed on it are rendered substantially slip resistant when resting on a tray or table which may be subject to sudden movement. The non-slip place mat is particularly useful for airline serving trays.
