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.
Claims36
A non-slip place mat comprising:
- a. a paper sheet, said sheet comprising a composition coating on both sides;
- and
- b. said composition coating comprising a blend of water, a water soluble salt, a wax and a polymeric material having a molecular weight greater than the wax.
A paper place mat comprising:
- a. a printed sheet;
- and
- b. a composition coating comprising a blend of water, sodium borate, beeswax and a polymeric material having a molecular weight of at least about 5,000.
A method for preparing a coating composition for a paper place mat to render the mat slip resistant, comprising:
- a. heating an amount of water;
- b. melting an amount of wax;
- c. adding to the heated water of step a., an amount of a water soluble salt;
- d. adding the wax of step b. to the mixture of step c.;
- and
- e. adding the mixture of step d. to a polymeric material.
A non-slip place mat comprising;
- a paper sheet, said sheet comprising a coating composition which comprises a blend of water, a water soluble salt, a wax and a polymeric material having a molecular weight greater than the wax on both sides of said sheet, said coating composition comprising means to provide slip resistance between one side of the mat and a tray surface, and slip resistance between the other side of the mat and articles disposed on the other side, and further comprising printing on said other side of said sheet and the composition coating being disposed on the printing and the printing being visible through the coating composition on said other side.
