ABSTRACT:
A non-slip place mat is disclosed which comprises a web such as a paper sheet, and a composition coating comprising a blend of water, a water-soluble salt, a wax and a polymeric material, which both coats and impregnates the web, e.g. 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. The present place mat is characterized by the provision of a generally rectangular planar flexible web, which is indented along two opposed edges. The web is multi-layered, i.e. coated, and the four corners of the web are rounded off, so that each corner is defined by a curved periphery. A plurality of place mats in a roll and arrayed in tandem, i.e. juxtaposed seriatim, is also contemplated, each two adjacent mats being detachably attached to each other by a weakened zone comprising a rectilinear array of spaced-apart and typically circular perforations, each array of perforations extending transverse to the longitudinal axis of the rolled-up line of place mats, i.e. parallel to the central longitudinal axis of the cylindrical roll.
